Java Program to Convert int to String

by

In the previous article we have discussed Java Program to Convert String to Boolean

In this article we will see how to convert a character to string.

Program to Convert int to String

Before starting the actual program, let’s see some examples of both the types.

Example-1: int type

int a = 4;
int b = 78;
Example-2: String type 

String a = "BtechGeeks"; 
String b = "B";

Let’s see different ways to do.

Our website provided core java programs examples with output aid beginners and expert coders to test their knowledge gap and learn accordingly.

Method-1 : Java Program to Convert int to String Using valueOf() method

Integer can be converted to string by using  valueOf() , let’s see how it actually works.

String.valueOf() is a method which will simply typecasts below-given parameter to strings always. It is an inbuilt method of String class in java.

Approach :

  1. Take a Integer value and store it in a Integer variable input1.
  2. Then pass that input1 variable as parameter to String.valueOf( ) method which will convert the Integer to string value and return it .
  3. Store that string value in a variable output.
  4. Display the result .

Program :

import java.util.Scanner;

public class Main
{
    public static void main(String[] args)
    {
        // creating scanner object
        Scanner sc = new Scanner(System.in);
        // input a integer value through scanner class
        System.out.print("Enter a Integer number : ");
        int input1=sc.nextInt();
        // converting to string
        String output = String.valueOf(input1);
        System.out.println("Converted String is : "+output);
    }
}
Output : 

Enter a Integer number : 5
Converted String is : 5

Method-2 : Java Program to Convert int to String Using toString() method

Integer can be converted to string by using  toString() , let’s see how it actually works.

Approach :

  1. Take a Integer value and store it in a Integer variable input1.
  2. Then pass that input1 variable as parameter to Integer.toString() method which will convert the Integer to string value and return it .
  3. Store that string value in a variable output.
  4. Display the result.

Program :

import java.util.Scanner;

public class Main
{
    public static void main(String[] args)
    {
        // creating scanner object
        Scanner sc = new Scanner(System.in);
        // input an integer value through scanner class
        System.out.print("Enter a Integer number : ");
        int input1=sc.nextInt();
        // converting to string
        String output = Integer.toString(input1);
        System.out.println("Converted String is :"+output);
    }
}
Output : 

Enter a Integer number : 5
Converted String is  :5

Method-3 : Java Program to Convert int to String Using “+” operator

Integer can be converted to string by using  “+” operator.Let’s see how it works.

Approach :

  1. Take a Integer value and store it in a Integer variable input1.
  2. Take a string variable and concatenate “+” with the input variable which will treated as String.
  3. Display the result.

Program :

import java.util.Scanner;

public class Main
{
    public static void main(String[] args)
    {
        // creating scanner object
        Scanner sc = new Scanner(System.in);
        // input an integer value through scanner class
        System.out.print("Enter an Integer number : ");
        int input1=sc.nextInt();
        // converting to string
        String output = " " + input1;
        System.out.println("Converted String is :"+output);
    }
}
Output : 

Enter a Integer number : 5
Converted String is :5

Method 4 : Java Program to Convert int to String Using format() method

Integer can be converted to string by using format() method. Let’s see how it actually works.

Approach :

  1. Take a Integer value and store it in a Integer variable input1.
  2. Then pass that input1 variable as parameter to String.format() method which will convert the Integer to string value and return it .
  3. Store that string value in a variable output.
  4. Display the result.

Program :

import java.util.Scanner;

public class Main
{
    public static void main(String[] args)
    {
        // creating scanner object
        Scanner sc = new Scanner(System.in);
        // input an integer value through scanner class
        System.out.print("Enter an integer number : ");
        int input1=sc.nextInt();
        // converting to string
        String output =String.format("%d", input1);
        System.out.println("Converted String is :"+output);
    }
}
Output:

Enter a Integer number : 5
Converted String is :5
