How to convert int to String in java?

package govind;

public class StringToIntConversion

{

public static void main(String[] args) {

int x=100;

String s1 = String.valueOf(x);

System.out.println(s1);//Now it will return "100"

System.out.println(x+400);//500 because + is binary plus operator

System.out.println(s1+400);//100400 because + is string concatenation operator

int y=200;

String s2 = Integer.toString(y);

System.out.println(s2);//"200"

System.out.println(s2+400);//200400 because + is string concatenation operator

int z=300;

String s3 = String.format("%d", z);

System.out.println(s3);//"300"

System.out.println(s3+400);//300400 because + is string concatenation operator

}
