Packages 6 - Create a Java program to create a package with 4 public classes, create the object in another file and call the function created in those classes.


            MyPackage/Class1.java
            package MyPackage;
            
            public class Class1 {
                public void function1() {
                    System.out.println("Function 1 from Class1");
                }
            }
            
             MyPackage/Class2.java
            package MyPackage;
            
            public class Class2 {
                public void function2() {
                    System.out.println("Function 2 from Class2");
                }
            }
            
             MyPackage/Class3.java
            package MyPackage;
            
            public class Class3 {
                public void function3() {
                    System.out.println("Function 3 from Class3");
                }
            }
            
            MyPackage/Class4.java
            package MyPackage;
            
            public class Class4 {
                public void function4() {
                    System.out.println("Function 4 from Class4");
                }
            }
            /MainApp.java
            import MyPackage.Class1;
            import MyPackage.Class2;
            import MyPackage.Class3;
            import MyPackage.Class4;
            
            public class Packages_6 {
                public static void main(String[] args) {
                    Class1 obj1 = new Class1();
                    Class2 obj2 = new Class2();
                    Class3 obj3 = new Class3();
                    Class4 obj4 = new Class4();
            
                    obj1.function1();
                    obj2.function2();
                    obj3.function3();
                    obj4.function4();
                }
            }
