When I try running the program it wont output the determineWinner method, I think there is something wrong with the way i called results. But I am not exactly sure?
public class rpsGame
{
public static void main( String [] args ) {
String userName = getUserName();
String playerChoice, computerChoice;
computerChoice = getComputerChoice();

I was wondering how I could make this code for rock paper scissors repeat itself 10x

im trying to modify the class to include a playerName variable and methods named assignName and getName. The assignName() method has a String parameter name that is assigned to playerName. The getName() method has to return the value of playerName.the problem i have when i run it is that it says there is a problem in the
public static String getName(){
return getName();
but im not sure what it is, this is all of my code:
public class RPS1 {
public static void main(String[] args) {
RPSGame rps = new RPSGame();
RPSPlayer rpsOpponent = new RPSPlayer();
int playerThrow;
Scanner input = new Scanner(System.in);
[code]....
When I try to compile the code it says " method determineWinner in class RPS cannot be applied to given types;" I think there is something wrong with the way i called the determineWinner method but i'm not what exactly is wrong.
public class RPS
{
public static void main( String [] args )
{
String result;
String userName = getUserName();
String playerChoice, computerChoice;
[code]....
I am trying to program a game of RPS.
View Replies View RelatedI'm doing a program where a user enters in exam results for students. Once he's entered the code, the code should split the results in stars in 4 categories.
I am working with a while loop that prints out infinite results. What I want to do is, if the user enters 2 digits, say "12", it should output 1 "*".
If the user enters "21" and "22", it should output "**".
There are 4 categories of marks which are marked with ints range1, range2, range3 and range4, which are user enter digits. Part 1 of the code is to split the user entered digits into its correct ranges. the ranges are 0-29, 30-39, 40-69 and 70-100. I've done the part where when the user enters a digit, it goes into the correct variable. After that when the user enters a digit over 100, the enter results should show up as stars. For example
Enter number =
21
22
44
66
44
23
11
111 (the 111 is where the program breaks and moves on)
So it should then display
0-29 ****
30-39
40-69 ***
70-100
Whatever I'm trying, it displays an infinite amount of stars. If I try to use break, It only outputs a single star, no matter how many digits I enter
Here is the code
int mark = 0;
int range1 = 0, range2 = 0, range3 = 0, range4 = 0;
int count1 = 0, count2 = 0, count3 = 0, count4 = 0;
while (mark >=0 && mark <=100) {

I need to create a Java program that takes an input a color code in HSV and outputs the equivalent RGB code and Vice versa.
Example:
If you test on the color RED in RGB:
Input: (255,0,0)
Output: (0,100%,100%)
If you test on the color RED in HSV:
Input0,100%,100%)
Output: (255,0,0)
I have one code [taking from on line SCJP exam preparation site]. I have 2 question in my mind:
1) addValue() is non static method then why it is running without object inside constructor. By this rule it should show compilation error.
2) With ref variable of parent always non overridden methods of parent run then it must value of 10 [If i forgot 1st point ]
But it is giving 40. Code is as below:
class Base{
int value = 0;
Base(){
addValue();
}
void addValue(){
value += 10;

The code is supposed to output a word from a sentence(from a sample file) with most frequently occurring letter in that word.
Example input: "Therefore, it is this word."
output: therefore
It currently uses 3 loops nested loops, is there a way to improve this?
public static String findWord(String file) throws IOException {
BufferedReader in = new BufferedReader(new FileReader(file));
String text, correctWord = null;
text = in.readLine();
StringTokenizer tokens = new StringTokenizer(text.toLowerCase(), " ,.?"); //split string into tokens of words only
int count = 0, numLetter = 0;

I'm having some trouble with getting this program to read an input of morse code and then produce an output of English. When typing in morse code for the phrase 'the string', the output looks something like this:
- .... .

s
t
r
i
n
The English-->Morse works just fine.

I have created a program that will take in input of paper names and authors. The next step of the program is to make references from paper to paper, and be able to add as well as list those reference, and i am lost as to where to go.I currently hold my instances of my paper class (the different papers I have stored) in a hash map. With the title being the key.
Is there a method as to where I can link keys? Do i need to use a seperate data structure? Or maybe add a new attribute to the paper class? I have attached the program as a zip file, If you open the zip file then its the methods in the Research SupportApp class .
I am having trouble while printing out form. So far I have succeeded to print it out.But my question is that I want jpanel to print out in Landscape rather then portrait.

I am trying to write a program that will generate a QR Code from an input text and also display some information about the input/output bits. So far I have created the frame and what to do next. And I'm not sure if I am on the right track since my level of programming is not that great. By the way, I am using zxing libraries from GitHub. I know, there are plenty of generators online for the QR Code, but that is not what I am looking for. As you can see on the attached image, I am more interested in the efficiency of encoding 2D data. Also, I noticed that almost all the online projects regarding 2D codes are for Android. Which is not very useful.

Some conversions work. For example, 77 will be correctly converted to 63, and 77777777 will be converted to 16777215. However, some conversions do not work. An example of this is 775002 gets converted to 74898.
I'm working on a simple site for my friend, and he asked me to link to his other site. I need to have the link to a specific search. For example, if I search for "Heathrow," I need to be able to link a button on the other site so that it can be clicked and directed to the search results on this page. Problem is that this is apparently all Java (which I know nothing of) and how to just copy a link to the results page.

Writing an program to add any 2 given Roman numerals together and return the results.
[I don't want to convert Roman numbers to decimal numbers & then add together, then convert in to Roman numerials ]
Is there any direct way to add roman numerials?
For example: I + I = II
III + I = IV
