Java Convert Integer to Hexadecimal String

In this Java core tutorial we learn how to convert an Integer value into a hexadecimal String in Java programming language.

How to convert Integer to Hex String in Java

In Java, with a given Integer value we can use the Integer.toHexString(int i) static method to convert it to a hexadecimal String as the example Java code below.

ConvertIntegerToHexExample.java

public class ConvertIntegerToHexExample {
    public static void main(String... args) {
        int intValue = 1024;

        // Convert Integer to Hexadecimal String
        String hexString = Integer.toHexString(intValue);

        System.out.println("int value: " + intValue);
        System.out.println("hexadecimal value: " + hexString);
    }
}

int value: 1024
hexadecimal value: 400

Happy Coding 😊
