How can you access other members of a class from within a class?

To access the members of a class from other class.

  1. First of all, import the class.
  2. Create an object of that class.
  3. Using this object access, the members of that class.

Can we access a public method from another class in same package?

Note that to use a method of a class from an unrelated class in the same package, the method must not be marked private . It can have no modifier, protected , or public , but it can’t be private . To use it in an unrelated class in a different package, it has to be public .

How can we use variable from another method?

You can’t. Variables defined inside a method are local to that method. If you want to share variables between methods, then you’ll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn’t always applicable).

Can a friend class access private methods?

Friend Class A friend class can access private and protected members of other class in which it is declared as friend. It is sometimes useful to allow a particular class to access private members of other class.

What are three different ways to access members of a class from another package?

The Java language supports four distinct access levels for member variables and methods: private, protected, public, and, if left unspecified, package.

Can two different classes contain methods with the same name?

What is Overloading? For convenience, Java allows you to write more than one method in the same class definition with the same name. For example, you can have two methods in ShoppingCart class named computeCost. Having two or more methods named the same in the same class is called overloading.

How do you call a method from another class without instantiating?

  1. YES, you can use the methods of a class without creating an instance or object of that class through the use of the Keyword “Static”.
  2. If you declare the method as “Static” then you can call this method by : *ClassName.MethodName()*

Can you declare multiple objects in the same class?

The advantage with this method, is that you can declare multiple objects in same class, and access them, without having to create instances for each. This is especially useful for parent- child classes. Or use a getter and setter method, which is actually the best practice.
