Java Program to convert int type variables to String
In the following example of Java program to convert int type variables to String :
Program :
public class Main {
    public static void main(String[] args) {
        int num = 123;
        
        // convert int to String using Integer.toString()
        String str = Integer.toString(num);
        
        System.out.println("Number: " + num);
        System.out.println("String: " + str);
    }
}

This program uses the Integer.toString() method to convert an int variable num to a String variable str. The output of the program will be:

Output :
Number: 123
String: 123

Note that there are also other ways to convert an int variable to a String variable in Java, such as using the String.valueOf() method or concatenation with an empty string.


Using String.valueOf() method :

Program :
public class Main {
    public static void main(String[] args) {
        
        // Initialize an int variable
        int number = 42;
        
        // Convert int to String using String.valueOf()
        String strNumber = String.valueOf(number);
        
        // Print both the int and String values
        System.out.println("Int value: " + number);
        System.out.println("String value: " + strNumber);
    }
}
Output :
Int value: 42
String value: 42


Using concatenation with an empty string :

public class Main {
    public static void main(String[] args) {
        
        // Initialize an int variable
        int number = 42;
        
        // Convert int to String using concatenation with an empty string
        String strNumber = "" + number;
        
        // Print both the int and String values
        System.out.println("Int value: " + number);
        System.out.println("String value: " + strNumber);
    }
}

Output :

Int value: 42
String value: 42
