java program have only one public class should main method only be part of that public class then any other class of that program?

Question

program running fine when main method is inside class QNA but give error when defined inside class test error: Main method not found in class QNA, please define the main method as: public static void main(String[] args) or a JavaFX application class must extend javafx.application.Application

import java.util.Scanner;
 public class QNA{
   Scanner scan= new Scanner(System.in);
   private int a;
   private int b;
   public void get_value(int x,int y)
   {
    a=x;
    b=y;
   }
   public int set_data()
   {
     int a=scan.nextInt();
     return a;
   }
   public int set1_data()
   {
     int b=scan.nextInt();
     return b;
   }   
}
class test
{
  public static void main(String[] args) {
         QNA q1= new QNA();
         int p=q1.set_data();
         int p1=q1.set1_data();
         int c=p+p1;
         System.out.println(c);
       }
}

It only work when we make the test class public and file save as test.java — Pooja Choudhary, Jul 31 '20 at 08:52

Class "test" is not an inner class of "QNA". The class "test" should be an inner class of "QNA" or it should be in its own file. And you need to target class "test", not class "QNA".
