Reverse String

In this example we are demonstrating the command line argument and displaying it in its backward direction on the console.

Description of program:

In the example given below, we are taking a command line argument and storing it in a string type array passed into the main method. Then we are taking a loop backward through the array of arguments and one more loop backwards through the characters in each argument and then printing out character j of argument i, adding the space at the end of each argument and at the end terminating the line when we're done.


public class ReverseString {

  

  public static void main(String[] args) {  

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

  for(int j=args[i].length()-1; j>=0; j--) {

  System.out.print(args[i].charAt(j));

  }

  System.out.print(" ");

  }

  System.out.println();

  }

}

Here is the output:
