Reversing a String In Java

Reversing a String In Java | How to Reverse a String in Java uisng charAt() Method.
Hello Readers...

In this post we are going to learn how to reverse a String in Java using for loop and charAt() method of String class. see example.

public class Reverse_String {

     public static void reverseString(String str) {

           String rev="";

           for(int i=str.length()-1;i>=0;) {

                rev=rev+str.charAt(i);

                i--;

           }

           System.out.print("Reverse of "+str+" is : "+rev);

     }

     public static void main(String[] args) {

          

           reverseString("DCBA");

     }

}

Output

Reverse of DCBA is : ABCD

In the above example i have created a simple class named as Reverse_String with main method. I have created a method named as reverseString() which takes String as an argument and declared a String empty/blank variable rev and performing the task of reversing of given String and print reverse of string. For any query use comment box, thanks.
