There are a couple ways you can reverse a string to make it backwards.
String code = "code";
System.out.println(code);
StringBuilder sb = new StringBuilder(code);
code = sb.reverse().toString();
System.out.println(code);String code = "code";
System.out.println(code);
char[] array = code.toCharArray();
for (int index = 0, mirroredIndex = array.length - 1; index < mirroredIndex; index++, mirroredIndex--) {
char temp = array[index];
array[index] = array[mirroredIndex];
array[mirroredIndex] = temp;
}
// print reversed
System.out.println(new String(array));
