Java Convert int to String

public class IntToStringExample1{  
public static void main(String args[]){  
int i=200;  
String s=String.valueOf(i);  
System.out.println(i+100);//300 because + is binary plus operator  
System.out.println(s+100);//200100 because + is string concatenation operator  
}}  

Output:

300
200100
