Method chaining, also known as named parameter idiom, is a common syntax for invoking multiple method calls in object-oriented programming languages. Each method returns an object, allowing the calls to be chained together in a single statement.

How do you call an interface method in Java?

In order to call an interface method from a java program, the program must instantiate the interface implementation program. A method can then be called using the implementation object.

How do methods work in Java?

A method is a block of code which only runs when it is called. You can pass data, known as parameters, into a method. Methods are used to perform certain actions, and they are also known as functions.

Can you call multiple methods on one line?

Method Chaining is the practice of calling different methods in a single line instead of calling different methods with the same object reference separately. Under this procedure, we have to write the object reference once and then call the methods by separating them with a (dot.).

Can two methods have the same name?

Having two or more methods named the same in the same class is called overloading. Two methods may share the same name, provided the number of parameters are different, or if they both have the same parameters, then there is at least one position, i where the parameter types differ.

What is Java Lambda?

Java lambda expressions are Java’s first step into functional programming. A Java lambda expression is thus a function which can be created without belonging to any class. A Java lambda expression can be passed around as if it was an object and executed on demand.

What is default method in Java?

To overcome this issue, Java 8 has introduced the concept of default methods which allow the interfaces to have methods with implementation without affecting the classes that implement the interface. Default methods are also known as defender methods or virtual extension methods.
