@ASNM: You can get it a few shortener by modifying your 'while' statement ;) while (len--) { reverseText+=text.charAt(len); }

public class Program { public static void main(String[] args) { String text="Hello World"; String reverseText=""; int len=text.length(); while (len>0){ len--; reverseText +=text.charAt(len); } System.out.println(reverseText); } }

You can use a simple "for" loop to iterate from the back of the string to the front. String test = "Test"; String rev = ""; for (int i = test.length(); i>0; i--) { rev += test.charAt(i); }
