    Default stuck on a "for" loop

    I want the code to print 3 lines of '@' with the same length.
    In the second line it will have text inside. I have a problem when [text%2] != 0.
    Tried to fix it with a for loop, but it will print 1 less or more '@' when [text % 2] = 1.
    If something isn't clear please ask me to explain, thanks a lot to helpers.

    package sos;
    public class triangle {
    	public static void main(String[] args) {
     
     
    	int x,y,z = 5; //z*2 = first and second lines / total.length
    	char w = '@';
    for (int j=0; j<z*2; j++) { //first line
    System.out.print(w);
    	}
    System.out.println();
    	String txt = " 312 ";
    	x = txt.length();
    	y = x/2;
    	z-=y;
    for (int i = 0; i < z; i++) { // second line (first half)
    System.out.print(w);
    }
    		System.out.print(txt.toUpperCase()); //middle TEXT
    			if (z%2==0) { //second line (second half)
    for (int i = 1; i < z; i++) {
    System.out.print(w);
    }
    		}
    			else {
    for (int i = 0; i < z; i++) {
    System.out.print(w);
    }	
    		}
    System.out.println();
    		z+=y;
    for (int j=0; j<z*2; j++) { //last line
    System.out.print(w);
    }
    System.out.println();
     
    System.out.println(txt.length());
    int d = txt.length();
    d%=2;
    	System.out.println(d);
     
    	}
    }

    Can you post the program's current output that shows what you are talking about?
    Also post what you want the output to look like.

    Can you fix the formatting of the source code you posted so it has proper indentations?
    If you don't understand my answer, don't ignore it, ask a question.

    Default Re: stuck on a "for" loop

    That is given back right now:
    @@@@@@@@@@
    @@@ 312 @@@
    @@@@@@@@@@

    Ssecond line (now) = @*3, space, '312', space, @*3. A total of 11 chars.

    That what i want to achive:
    @@@@@@@@@@
    @@@ 312 @@
    @@@@@@@@@@

    *Because the lines has to be exact in the same length by letters (including the spaces).

    Didn't quite understand your last request, Im just beginning.

    Is the problem that the second line has 3 @ after the 312 and you only want to have 2?


    Source code should have proper indentations on each line to make it easier to read and understand.
    For example only the first and last lines of the source code should start in the first column.
    The amount of indentation should show the nesting of the logic.
    Look at the posted code in other threads or anywhere. Most posted code has proper indentations.
    If you don't understand my answer, don't ignore it, ask a question.
