How to Convert Integer to String in Java ?

Answer

To convert an integer to a string in Java, you can use the String.valueOf() method or concatenate the integer with an empty string.

✐ Examples

1 Convert Integer to String using String.valueOf()

In this example,

We declare an integer variable named num and assign it a value of 42.
We then convert the integer num to a string using the String.valueOf() method and store the result in the variable strNum.
The String.valueOf() method converts the integer to its string representation.
Finally, we print the string representation of the integer to the console.

Java Program

// Convert Integer to String using String.valueOf()
public class Main {
    public static void main(String[] args) {
        int num = 42;
        String strNum = String.valueOf(num);
        System.out.println("String representation of integer: " + strNum);
    }
}

Output

String representation of integer: 42

2 Convert Negative Integer to String using Concatenation

In this example,

We declare a negative integer variable named negativeNum with a value of -10.
We then concatenate the negative integer negativeNum with an empty string and store the result in the variable strNegativeNum.
The concatenation operation converts the integer to its string representation.
Finally, we print the string representation of the negative integer to the console.

Java Program

// Convert Negative Integer to String using Concatenation
public class Main {
    public static void main(String[] args) {
        int negativeNum = -10;
        String strNegativeNum = negativeNum + "";
        System.out.println("String representation of negative integer: " + strNegativeNum);
    }
}

Output

String representation of negative integer: -10
