        public String reverse(String x) {
     
    	String result = "";
     
    	for (int i = 0; i < lenght(); i++) {
     
    	    result = x.charAt(i) + result;
    	}
    	return result;
    	    }
     
        public static void main(String args[]) {

    Default Re: Reverse a String

    you must use for (int i=0;i<result.length();i++)
    then your problem will be solved

    Where is the method: lenght() defined? The compiler can not find it in the code.
    What value do you want to use to control the for loop?

    @maz3r Did you test the code you posted?
