    Can you define a "word rectangle" and show an example?

    When you enter a word it will display it as a regular word then shift a letter to the right, and it will be in rows and columns for the amount of letters the word has. Example:

    COMPUTERS
    OMPUTERSC
    MPUTERSCO
    PUTERSCOM
    UTERSCOMP
    TERSCOMPU
    ERSCOMPUT
    RSCOMPUTE
    SCOMPUTER

    If the project is only changing the position of characters in a String, look at the String class's methods.
    And the StringBuilder and StringBuffer classes.

    Start by removing one character from the start of the String.
    Concatenate that character at the end of the String.
    Print it.
    Do it again until done.

    Um, I am sorry, I understand the methods, really I do, this is all I have so far, could you please show me how to do it. My teacher doesn't teach us at all how to do these things and I am so stuck on how to do it, please if you can. Here is what I have so far:

    package wordrectangle;
    import javax.swing.JOptionPane;
    import java.lang.String;

    public class WordRectangle {

    /**
    * @param args the command line arguments
    */
    public static void main(String[] args) {

    //Declare variables
    int word, str;

    //Ask the user to enter a word from a string and convert to a double
    String inputWord = JOptionPane.showInputDialog("Enter a word and this "
    + "program will make a word rectangle with it:");

    }
    }

    I understand the methods,
    If you understand the methods and how to use them and what they do, what are you waiting for to use some of them to solve the problem?
    A hint:
    1)extract two Strings from the one String. One with a single character, the other with the rest of the characters.
    abcd -> a and bcd
    2) concatenate the single character String at the end of the other String ->bcda

    Solve the problem one small step at a time.
    Take a String and move its first character to the end of the String. Can you do that?

    When that is done, what next?

    Ok I'm trying to figure this out......
    Here is what I have so far.... can you show me an example of what to do?

    package wordrectangle;
    import javax.swing.JOptionPane;
    import java.lang.String;
     
    public class WordRectangle {
     
        /**
         * @param args the command line arguments
         */
        public static void main(String[] args) {
     
            //Declare variables
            int count = 0;
            char firstLetter;
     
            //Ask the user to enter a word from a string and convert to a double
            String word = JOptionPane.showInputDialog("Enter a word and this "
                    + "program will make a word rectangle with it:");
     
            //Declare the length that will find the number of vowels in the sentence
            for (int i = 0; i < word.length(); i++) {
            firstLetter = word.charAt(0);
            word = word.substring(1, word.length());
            System.out.println(firstLetter + word);        
                }
            }   
        }

    What prints out when you execute the program? Is the output what you want?

    It outputs:

    computers
    omputers
    mputers
    puters
    uters

    And, no that is not what I want.

    It looks like you are getting the second part of the String OK. what is happening to the first letter that is supposed to be concatenated to the end of the String? It looks like you remove it and throw it away

    Use the + operator:
    "sdd" + "e" -> "sdde"

    Have you tried it yet to see what happens? See posts #6 & #8 where I gave the steps the code should do.

    Default Re: How to Create a Word Rectangle

    All I got it to work but... how would I loop it to make that word only have to right rows and columns for the specific word. Ex computers, 9 rows, 9 columns? Here is the code so far:
    package wordrectangle;
    import javax.swing.JOptionPane;
    import java.lang.String;

    public class WordRectangle {

    /**
    * @param args the command line arguments
    */
    public static void main(String[] args) {

    //Declare variables
    int count = 0;
    char firstLetter;

    //Ask the user to enter a word from a string and convert to a double
    String word = JOptionPane.showInputDialog("Enter a word and this "
    + "program will make a word rectangle with it:");

    //Declare the length that enable the word to be mixed up in the sentence

    for (int i = 0; i < word.length(); i++) {
    firstLetter = word.charAt(0);
    word = word.substring(1, word.length());
    System.out.println(firstLetter + word);
    i = word.indexOf(word);
    i = word.indexOf(firstLetter);
    word += firstLetter;
    */

    Please post the output from the program and add some comments describing what you want to change.

    Please Edit your post and wrap your code with[code=java]<YOUR CODE HERE>[/code] to get highlighting. You did not use code tags.


    Why does the code change the value of i two times inside of the loop?
    It is dangerous to change the loop control variable inside the loop.

            //Declare variables

            char firstLetter;
     
            //Ask the user to enter a word from a string and convert to a double
            String word = JOptionPane.showInputDialog("Enter a word and this "

            //Declare the length that enable the word to be mixed up in the sentence 
     
            for (int i = 0; i < word.length(); i++) {
            firstLetter = word.charAt(0);
            word = word.substring(1, word.length());
            System.out.println(firstLetter + word);
            i = word.indexOf(word);
            i = word.indexOf(firstLetter);
            word += firstLetter;
     
     
     
     
                }
            }   
        }

    I want the program to stop when it makes a 9 x 9 rectangle. (Depending on the word, using a "computers" as an example. The program keeps running so its 9 x Inifinity.) If you could change it that would be awesome.

    If your are not sure, then remove them.
