Java Code Example :

This java example source code demonstrates the use of toString() method of Integer class. Basically we ask for an int input from the console, and then we use the scanner to get the value. After that we assign the value to an Integer wrapper class and then get the string equivalent using the toString() method of Integer class.

package com.javatutorialhq.java.examples;

import java.util.Scanner;

import static java.lang.System.*;

/*
 * This example source code demonstrates the use of 
 * toString() method of Integer class.
 */

public class IntegerToString {

	public static void main(String[] args) {
		// Ask user input
		System.out.print("Enter Desired Value:");
		// declare the scanner object
		Scanner scan = new Scanner(System.in);
		// use scanner to get the value from user console
		int intValue = scan.nextInt();
		// close the scanner object
		scan.close();
		Integer myValue = new Integer(intValue);
		String value = myValue.toString();
		out.println("String Value is " + value);

	}

}
