Java Integer toHexString Method with Examples

The java.lang.Integer.toHexString() method returns a string representation of the integer argument as an unsigned integer in base 16.

Let us now see an example −

Example

import java.lang.*;
public class Main {
   public static void main(String[] args) {
      int i = 160;
      System.out.println("Number = " + i);
      System.out.println("Hex = " + Integer.toHexString(i));
   }
}

Output

Number = 160
Hex = a0

Example

Let us now see another example for negative number −

import java.lang.*;
public class Main {
   public static void main(String[] args) {
      int i = -160;
      System.out.println("Number = " + i);
      System.out.println("Hex = " + Integer.toHexString(i));
   }
}

Output

Number = -160
Hex = ffffff60
