Question

i have a 2 array with that display value of a matrix .I have use 2 for loops and a string builder to display the values.The problem is that the values are displayed in a single line i want it to display it as a matrix format.

I my program i use string 1=”bbabb” and string 2=”aaabb” i compare each value and build a matrix accordingly with give me 25 values…but when displayed in my text area it show it like that “0000000100001000102101013” but i want to display it like that

0 0 0 0 0 
0 0 1 0 0
0 0 1 0 0
0 1 0 2 1
0 1 0 1 3

I am quite new to java.Can someone explain me the logic or give me a sample code where i can change the first string format to the second one.Thank you

You need to append a newline "\n" in between each row, when using your StringBuilder, e.g.

StringBuilder sb = new StringBuilder();
sb.append("row1");
sb.append("\n");
sb.append("row2");
System.out.println(sb.toString());

Obviously, adapt the above to fit in with your nested for loops…
