Question

Answer 1

You can create a static void function and then call it on your created class. Maybe it can help?

Answer 2

One way is to accept input in the static method.

import java.io.BufferedReader;
import java.io.InputStreamReader;

class HelloWorld {
  public static void main(String[] args) {
    System.out.println("Hello, World!"); 
  }

  static {
    try {
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        int num1 = Integer.parseInt(br.readLine());
        int num2 = Integer.parseInt(br.readLine());
        System.out.println("Sum of two numbers is " + (num1 + num2));
    } catch (Exception e) {
        System.out.print(e.toString());
    }
  }
}
