Write a Java Program to reverse a string without using String inbuilt function reverse().

Method 1:

1	public class FinalReverseWithoutUsingInbuiltFunction {

2	public static void main(String[] args) {

3	String str = "Saket Saurav";

4	char chars[] = str.toCharArray();  // converted to character array and printed in reverse order

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

6	System.out.print(chars[i]);

7

}

8

}

9

}

Output:

varuaS tekaS

Method 2:

1	import java.util.Scanner;

2

3	public class ReverseSplit {

4

5	public static void main(String[] args) {

6	// TODO Auto-generated method stub

7	String str;

8	Scanner in = new Scanner(System.in);

9	System.out.println("Enter your String");

10	str = in.nextLine();

11	String[] token = str.split("");    //used split method to print in reverse order

12	for(int i=token.length-1; i>=0; i--)

13

{

14	System.out.print(token[i] + "");

15

}

16

17

}

18

19

}

Output:

Enter your String
