Just a quick question, how do you set something == to char and int in an if statement (java)
Write a method checkCharacter() which has 2 parameters: A String, and a specified index (an int). Method checkCharacter() checks the character at the specified index of the String parameter, and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character.
Ex: The method calls below with the given arguments will return the following Strings:
checkCharacter("happy birthday", 2) returns "Character 'p' is a letter"
checkCharacter("happy birthday", 5) returns "Character ' ' is a white space"
checkCharacter("happy birthday 2 you", 15) returns "Character '2' is a digit"
checkCharacter("happy birthday!", 14) returns "Character '!' is unknown"
Your program must define the method:
public String checkCharacter(String word, int index)
this is what i got to but im stuck on how to find out if its a char or int
public class TollCalculation {
public double calcToll(int hour, boolean isMorning, boolean isWeekend) {
Scanner scnr = new Scanner(System.in);
int timeHour; // Time of travel hour (24 hour format)
int timeMinute; // Time of travel minute
int inputColon; // Used to read time format
String userInput; // User specified time
double tollAmount;
}
public static void main(String[] args) {
TollCalculation tollObj = new TollCalculation();
// Test the three samples from the specification.
System.out.println(tollObj.calcToll(7, true, false));
System.out.println(tollObj.calcToll(1, false, false));
System.out.println(tollObj.calcToll(3, true, true));
}
}
This is the requested code in java.
public class CharTest {
public static String checkCharacter(String text, int index) {
if (0 <= index && index <= text.length()) {
char ch = text.charAt(index);
if (Character.isLetter(ch)) {
return ch + " is a letter";
} else if (Character.isDigit(ch)) {
return ch + " is a digit";
} else if (Character.isWhitespace(ch)) {
return ch + " is a whitespace character";
} else {
return ch + " is an unknown type of character";
}
} else {
return "index " + index.toString() + " is out of range";
} // end if
} // end function checkChar()
public static void main(String[] args) {
// Test the three samples from the specification.
System.out.println(checkCharacter("happy birthday", 2));
System.out.println(checkCharacter("happy birthday", 5));
System.out.println(checkCharacter("happy birthday 2 you", 15));
} // end function main()
} // end class CharTest
The function checkcharacter(text, index) returns a string value describing the kind of character found at the position in text specified by index; whether it was a letter, digit, whitespace, or an unknown kind of character.
How it does that is to make use of respective functions defined within the Character class in java. That is
isLetter(char) returns a bool specifying if the char parameter is a letter.isDigit(char) returns a bool specifying if the char parameter is a digit.isWhitespace(char) returns a bool specifying if the char parameter is a whitespace character.It calls these functions in an if statement. These else part of the if statement is then executed if the character is neither a letter, digit, or whitespace.
Finally, the function main() calls checkCharacter() three times to test the function and return the results to the console.

Turtle graphics windows do not automatically expand in size. What do you suppose happens when a Turtle object attempts to move beyond a window boundary
When a turtle object attempts to move beyond a window boundary, the turtle object stops because it cannot move outside the window boundary.
The turtle graphics window is simply a graphics window that is used as a playground when drawing turtles.
A turtle object is always in the turtle graphics window.
This in other words mean that, the turtle object cannot exceed the boundaries of the turtle graphics window
An attempt to move the turtle object outside its window will stop the turtle object;

In order to send and receive packets in the Internet, hosts require an IP address. What are the 2 ways a host can obtain an IP address
Answer:
Explanation:
An IP address is a 32-bit number. It uniquely identifies a host (computer or other device, such as a printer or router) on a TCP/IP network.
IP addresses are normally expressed in dotted-decimal format, with four numbers separated by periods, such as 192.168.123.132. To understand how subnet masks are used to distinguish between hosts, networks, and subnetworks, examine an IP address in binary notation.
For example, the dotted-decimal IP address 192.168.123.132 is (in binary notation) the 32-bit number 110000000101000111101110000100. This number may be hard to make sense of, so divide it into four parts of eight binary digits.
These 8-bit sections are known as octets. The example IP address, then, becomes 11000000.10101000.01111011.10000100. This number only makes a little more sense, so for most uses, convert the binary address into dotted-decimal format (192.168.123.132). The decimal numbers separated by periods are the octets converted from binary to decimal notation.
For a TCP/IP wide area network (WAN) to work efficiently as a collection of networks, the routers that pass packets of data between networks don't know the exact location of a host for which a packet of information is destined. Routers only know what network the host is a member of and use information stored in their route table to determine how to get the packet to the destination host's network. After the packet is delivered to the destination's network, the packet is delivered to the appropriate host.
For this process to work, an IP address has two parts. The first part of an IP address is used as a network address, the last part as a host address. If you take the example 192.168.123.132 and divide it into these two parts, you get 192.168.123. Network .132 Host or 192.168.123.0 - network address. 0.0.0.132 - host address.
The second item, which is required for TCP/IP to work, is the subnet mask. The subnet mask is used by the TCP/IP protocol to determine whether a host is on the local subnet or on a remote network.
In TCP/IP, the parts of the IP address that are used as the network and host addresses aren't fixed. Unless you have more information, the network and host addresses above can't be determined. This information is supplied in another 32-bit number called a subnet mask. The subnet mask is 255.255.255.0 in this example. It isn't obvious what this number means unless you know 255 in binary notation equals 11111111. So, the subnet mask is 11111111.11111111.11111111.00000000.
Lining up the IP address and the subnet mask together, the network, and host portions of the address can be separated:
11000000.10101000.01111011.10000100 - IP address (192.168.123.132)
11111111.11111111.11111111.00000000 - Subnet mask (255.255.255.0)
The first 24 bits (the number of ones in the subnet mask) are identified as the network address. The last 8 bits (the number of remaining zeros in the subnet mask) are identified as the host address. It gives you the following addresses:
11000000.10101000.01111011.00000000 - Network address (192.168.123.0)
00000000.00000000.00000000.10000100 - Host address (000.000.000.132)
So now you know, for this example using a 255.255.255.0 subnet mask, that the network ID is 192.168.123.0, and the host address is 0.0.0.132. When a packet arrives on the 192.168.123.0 subnet (from the local subnet or a remote network), and it has a destination address of 192.168.123.132, your computer will receive it from the network and process it.
Almost all decimal subnet masks convert to binary numbers that are all ones on the left and all zeros on the right. Some other common subnet masks are:
Decimal Binary 255.255.255.192 1111111.11111111.1111111.11000000 255.255.255.224 1111111.11111111.1111111.11100000
Internet RFC 1878 (available from InterNIC-Public Information Regarding Internet Domain Name Registration Services) describes the valid subnets and subnet masks that can be used on TCP/IP networks.

Describe the two problems that appear in the construction of large programs that led to the development of encapsulation constructs.
Two problems that can lead to the development of encapsulation constructs when creating large programs are the complexity of data and the lack of security in sensitive data.
We can arrive at this answer because:
Encapsulation constructs are designed to prevent data from being invaded by unauthorized person.These constructions must be done without causing inconsistencies in the system, interfering with codes, and increasing the complexity of data. For this reason, large programs that present high complexity and difficult codes, demand the use of encapsulation constructs, so that their data does not become more complex.Encapsulation constructs are also necessary when there are flaws in data security and it is not possible to keep them away from the attack by intruders.Although there are other ways to accomplish these goals, encapsulation constructs are widely used because of their simplicity and efficiency.

If you were a hackathon team manager, how could you best address the conflict created by having more volunteers than open roles
There are various ways to resolve conflict. Addressing conflict by the team manage is by:
Control conflict by expanding the resource base Eliminate conflict by assigning volunteers to another project team.There are a lot of ways an individual can handle conflict. One of which is to expand the resource base.
Example: Supporting team manager receives 4 budget requests for $150,000 each. If he has only $200,000 to distribute, there will be conflict at this stage because each group will believe its proposal is worth funding and will not be happy if not fully funded. So the best thing to do is to expand the resources allocated.
The right way to fix this conflict is to tell your volunteers in advance that some of them will not be doing different tasks etc.

In this tutorial you will learn how you to build and setup a home or small area network and connect it to the Internet.
Explanation:
Choosing a Wired or Wireless Network
Do You Build a wired or Wireless Network? which is best?
Early (pre 2008) home networks were predominately wired networks.
Wired networks use Ethernet over UTP cable and tend to be faster than wireless networks, which is an important consideration if you are a gamer. The simple wired home network diagram below shows a minimum setup with a switch and broadband router.

Wired Network Advantages
Fast typically 100 Mbps to 10 Gbps
Secure and reliable.
Wired Network Dis-Advantages
Doesn’t work with devices that don’t have an Ethernet port e.g. tablets and smart phones.
Not so easy and fast to setup as it requires running cables. However Homeplug or powerline adapters can be used instead.
Not so easy for visitors and mobile devices (laptops) to connect to.
Main Uses
It Is best used for network backbone i.e. connecting between router,network switches and wireless access points on different levels (floors).
