asked how to print "kim chong" backwards; and are right to think about reversing the character order. A shorter, idiomatic option in Java is to use the standard library; for full Unicode safety use a code-point aware approach.

Quick one-liner (works well for ASCII and simple text):

String reversed = new StringBuilder("kim chong").reverse().toString();
System.out.println(reversed); // prints "gnohc mik"

For text that may include surrogate pairs (emoji, rare scripts) prefer reversing by code points so pairs are preserved:

String s = "kim chong";
int[] cps = s.codePoints().toArray();
StringBuilder sb = new StringBuilder();
for (int i = cps.length - 1; i >= 0; i--) {
    sb.appendCodePoint(cps[i]);
}
String reversed = sb.toString();

Note: even the code-point approach can split grapheme clusters made of base characters plus combining marks. For true user-visible character reversal look into Java's BreakIterator or ICU4J, and see the standard API docs for StringBuilder and String.codePoints() for details.

first convert the string to char array and display the elements of that array backwards. There is a method in the String class which converts that string into char array.

JoCamps is correct, as a hint for how to display the array backwards, consider writing a for loop that starts at the ending index of the array and goes backwards, printing out the element at each index.
