In this example, the this keyword is used to refer to the instance variables name and age and the instance methods setName, setAge, getName, and getAge of the Person object. The this keyword is also used to pass the current object as an argument to a method or constructor. For example...
The core philosophy behind its creation—interoperability across disparate devices—remains the strongest argument for favoring Java for new enterprise applications. Java’s object-oriented architecture allows you to create modular programs and reusable code, shortening development cycles and extending the lon...

A new HashMap is created with the capacity specified by the argument 'capacity'. HashMap ( int capacity, float loadFactor ) The constructor creates a new HashMap with the capacity and loadFactor values. Conclusion In this article, we have learned that a hashmap is a key-value pair collect...
Something to remember about overloading is that you can't have more than one method with the same name, number, and type of argument because that declaration doesn't let the compiler understand how they're different. Also, you can't declare two methods as having identical signatures, even ...
