What is purpose of method overloading?

Method overloading increases the readability of the program. This provides flexibility to programmers so that they can call the same method for different types of data. This makes the code look clean. This reduces the execution time because the binding is done in compilation time itself.

What is the benefit of overloading?

Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).

What is constructor overloading explain with example?

The constructor overloading can be defined as the concept of having more than one constructor with different parameters so that every constructor can perform a different task. Consider the following Java program, in which we have used different constructors in the class.
