A method is a set of statements that collectively perform a specific task and can be invoked any number of times by using its name. In other words, these lines of code are grouped together to form a method and this defined method can be used any number of time. It reduces the length of the code and improves readability.
Syntax:
return_type method (parameter/ Argument) { // set of statements or body }
Explanation:
return_type: It means what type of value would a method be returned. It can be Boolean, integer, floating, char and even objects. If the method name is followed by void, then it would return nothing.
method_name: It is basically an identifier which represents the name of the method.
parameter or argument: These are nothing but a set of inputs where each input is separated by a comma and defined with a datatype preceded with the identifier.
class square{ int area; int area(int side){ area = side*side; return area; } void display(int area) { System.out.println(" Area of the Square = "+area); } } public class Box { public static void main(String[] args) { square obj = new square(); int output; output= obj.area(5); obj.display(output); } }
Output:
