Java Program to Convert int to String

What is int in Java ?

“int” is a primitive data type in Java that is used to represent integers (whole numbers) within a certain range of values. The range of values that can be stored by an “int” is from -2^31 to 2^31-1. The “int” data type is commonly used in mathematical operations and to represent arrays of integers.

What is String in Java ?

In Java, the “String” data type is a class that represents a sequence of characters. It is used to store and manipulate text-based data. Unlike primitive data types, such as “int” or “float”, which hold a single value, a String object can hold multiple characters.

Ways to Convert int to String  : 

Syntax :

int myInt = 123;
String myString = String.valueOf(myInt);

Syntax :

int myInt = 123;
String myString = Integer.toString(myInt);

Syntax :

int myInt = 123;
String myString = "" + myInt;

Example 1 : 

Run
public class Main {
    public static void main(String[] args) {
        int myInt = 123;
        String myString = String.valueOf(myInt);
        System.out.println("My int value as a String is: " + myString);
    }
}

Output :

My int value as a String is: 123

Example 2 : 

Run
public class Main {
    public static void main(String[] args) {
        int myInt = 123;
        String myString = Integer.toString(myInt);
        System.out.println("My int value as a String is: " + myString);
    }
}

Output :

My int value as a String is: 123

Example 3 :

public class Main {
    public static void main(String[] args) {
        int myInt = 123;
        String myString = "" + myInt;
        System.out.println("My int value as a String is: " + myString);
    }
}
