What are method signatures?

A method signature can be very simply defined as the method name followed by the parameter types. Say, for example, we have a method that adds two numbers. This is the method signature of this kind of method:

addNum(int, int)

The actual method is shown in the following code block. This method has to be invoked from another method or from the main() method, as in the following:

public int addNum(int num1, int num2) {    int result = num1 + num2;    return result;}Method call: addNum(10,20)Output: 30

In the sections that follow, we will be looking at the method signatures of various important methods. But first, let's understand a concept of Java called List, which we will see in the findElements method.
