Answer 1

public class Program
{
public static void main(String[] args) {
Greetings y = new Greetings();
y.set(6);
System.out.println(y.x);
}
}
public class Greetings
{
int x;
public void set(int num){
x = num;
}
}

Two minor mistake committed by you in this code are,

1) You don't need a return type in a setter because you are getting nothing but only setting a value to a variable. [line 11]

2) You already made an object y of class Greetings, so try to use object "y" to access the property and not the class name itself. [line 6]
