Discussion :

The string valueOf(int i) method is simply to get a String equivalent of int method parameter. This method be statically accessed which means we should call the method like String.valueOf(int i).

Java Code Example :

This example source code demonstrates the use of valueOf(int i) of String class. Below are different examples of getting a value of int. As you would noticed we have used the unboxing functionality to transform an Integer object into primitive int datatype and then get the string equivalent using the valueof method.

package com.javatutorialhq.java.tutorial.string;

/*
 * Java example source code to get the value of int data type
 */

public class StringValueOfInteger {

	public static void main(String[] args) {

		int val = 1;
		Integer i = 100;
		System.out.println(String.valueOf(val));
		System.out.println(String.valueOf(i));
		System.out.println(String.valueOf(-3));
	}

}
