Reversing a String - Practice

Problem: The output should be reverse of a string input.

For example, Input:  greatlearning;

Output: gninraeltaerg;

Input: to;

Output: ot;

public class reversingString {

public static void main(String[] args) {

// TODO Auto-generated method stub

String original = "greatlearning";

reversingString obj = new reversingString();

char [] get_result = obj.mirrorstring(original);

System.out.println(get_result);

   

}

public char[] mirrorstring(String original){

char [] chars = original.toCharArray();

for (int i=0,j=0; i<chars.length && j<chars.length/2; i++,j++){

char ch = chars[chars.length-1-j];

chars[chars.length-1-j] = chars[i];

chars[i]= ch;

}

return chars;

}

}
