THIS IS MY CODE BUT IT IS NOT GIVING THE RIGHT OUTPUT

package main;
import java.util.*;

public class Year_Conversion {
public static void main(String[] args) {
String s1;
System.out.println("Input string in the following format dd-mm-yy:");
Scanner sc=new Scanner(System.in) ;
s1=sc.next();
convertDate(s1);
}
public static String convertDate(String s1)
{
String ans = null;
String[] parts=s1.split("-");
int d=Integer.parseInt(parts[0]);
int m=Integer.parseInt(parts[1]);
int y=Integer.parseInt(parts[2]);
if(d<10)
{
ans=ans+"0"+d;
}
else
{
ans=ans+d;
}
if(m<10)
{
ans=ans+"0"+m;
}
else
{
ans=ans+m;
}
ans=ans+"19"+y;
return ans;
}
}

What output do you get? Rather than convert to integer to determine if you need to prefix a zero why not use strings length, if it is 1 you need a zero...

1. DON'T SHOUT! Typing in all capitals on the internet is considered shouting. Typing your entire message in capitals is rather rude. 2) If you want someone to help you get the "right output", then you need to tell us what the "right output" is. Show us several examples of what you type in, what the expected output is, and what the actual output is. Without that information, we can't help you.

Should be empty string not null Also noting that the code you have is not printing the result.
