Lesson: Access modifiers

 There are four access modifiers: public, private, protected, default

1. Public -> access from everywhere

2. Private -> access only inside the same class

3. Protected -> access from the same package and inherited class

4. Default -> also called package private, access from the same package

-- Default

package org.package1;

public class Access1 {
    int hours = 1;
    int minutes = 60;
}

package org.package1;

public class Access2 {
    public static void main(String[] args) {
        Access1 access1 = new Access1();
        System.out.println(access1.hours);
        System.out.println(access1.minutes);
    }
}
