"complementary angles" or "supplementary angles" as per the user's choice.
(Complementary angles sum of angles = 90°, Supplementary:- Sum of angle = 180°)

If you have any problem related to it ask me in the comments...

package com.company;

import java.util.Scanner;

public class Main {

   public static void main(String[] args)

   {

       Scanner sc = new Scanner (System.in);

       System.out.println("Enter angle 1: ");

       double a1 = sc.nextDouble();

       System.out.println("Enter angle 2: ");

       double a2 = sc.nextDouble();

       if (a1+a2==90) {

           System.out.println("Supplementary angles");

       }

       else if (a1+a2==180) {

           System.out.println("Complementary angles");

       }

       else {

           System.out.println("Neither supplementary nor complementary angles");

       }

   }

}
