Getter and setter

Question

Is it possible to use the Setter method only in java like this code?

public class GettersAndSetters {

public static void main(String[] args) {

TestSetter setter2 = new TestSetter();

setter2.setNumber(10); 

System.out.println(num);

}
}

public class TestSetter {

    private int number;

    public void setNumber(int num) {

        this.number = num;

    }

}

Answer 1

System.out.println(num); // error

This is where the getter would be used.

System.out.println(setter2.getNumber());

You can get and set the variable if it were public or package protected, without the getters/setters.
But just keep it private for encapsulation.

But yes, if you don't need to get the variable from an outside class, then you don't need a getter.
