private int idx;

private String text, revText;

public static void main(String[] args) {

Scanner sc=new Scanner(System.in);

System.out.print("Enter a string :");

String input=sc.nextLine();

ReverseString greeting = new ReverseString(input);

System.out.println(" Enterd String :"+input);

greeting.Revers(input);

System.out.println("Reversed String :"+greeting.getText());

}

public void Revers(String input) {

if (idx == text.length())

return;

revText = text.charAt(idx) + revText;

idx++;

Revers(input);

public ReverseString(String _text) {

idx = 0;

text = _text;

revText = "";

}
