Integer to two digits hex in Java

Integer to two digits hex in Java

To convert an integer to a two-digit hexadecimal representation in Java, you can use the String.format method with the %02X format specifier. Here's an example:

public class IntegerToHexExample { public static void main(String[] args) { int number = 42; // Replace with your integer // Convert the integer to a two-digit hexadecimal string String hexString = String.format("%02X", number); System.out.println("Hexadecimal representation: " + hexString); } }

In this code:

  • We define an integer called number with the value you want to convert to a hexadecimal representation (in this case, 42).

  • We use String.format("%02X", number) to convert the integer to a two-digit hexadecimal string. The %02X format specifier ensures that the output has at least two digits and is in uppercase.

  • We then print the hexadecimal representation using System.out.println.

When you run the code with number set to 42, the output will be:

Hexadecimal representation: 2A

You can replace the number variable with any integer value you want to convert to a two-digit hexadecimal representation.
