If two classes are within the same package you dont have to use import statement

(a)

package pack1;

public class ClassA extends ClassB {

    public static void main(String[] args) {

        /*

          You can see from here when we are importing a class within the same package

          say pack1 you need not explicitly import the package say import pack1.ClassB

          also in the class A if you see we have not given any declaration for the integer

          variable i (without any declaration it will take it as default or else protected or public)

        */

        ClassB obj = new ClassB();
        System.out.println("The Output in Class A is " + obj.i);

    }

}

(b)

package pack1;

public class ClassB {

    //Note : If you declare it as private it will show error in ClassA as the classes are not same

    //Can be declared protected, public or (just like that..that is default)

    int i=10;

}

Answer

----------

The Output in Class A is 10
