Question

The question is about stating the output of the program from output 1 till output 8, each output number is marked on the test class

for example: //output 1, //output 2

Explanation / Answer

Answer)
The given program is :
public class Room{
private int size;
public static int num = 1;
  
public Room(){this(5);}
public Room(int s){size=s;}
public Room(int a, int b){size=a; num = b;}
  
public int getSize(){return size;}
public void change(int x){size=x; num++;}
public static void change(){num++;}
public Room same(){return this;}
  
public String toString(){
return "size ="+size+", id="+num;
}
  
}

public class TestRoom {
   public static void main(String[] args){
Room r1 = new Room(20,4);
System.out.println("r1: "+r1);
System.out.println("Room.num "+Room.num);
Room r2=new Room();
System.out.println("r2: "+r2);
r1.change(35);
System.out.println("r1: "+r1);
System.out.println("r1: "+r2);
Room special = r1.same();
r1.change(15);
System.out.println("special: "+special);
System.out.println("r1: "+r1);
Room.change();
special.change(0);
System.out.println("special: "+special);
}
}

The output of the program is:
r1: size =20, id=4
Room.num 4
r2: size =5, id=4
r1: size =35, id=5
r1: size =5, id=5
special: size =15, id=6
r1: size =15, id=6
special: size =0, id=8

Now let's fillup the output sheet:
Output 1: r1: size =20, id=4
Output 2: Room.num 4
Output 3: r2: size =5, id=4
Output 4: r1: size =35, id=5
Output 5: r1: size =5, id=5
Output 6: special: size =15, id=6
Output 7: r1: size =15, id=6
Output 8: special: size =0, id=8

I hope the answer helps you.
