Declaring a Java Method

The syntax to declare a method is:

modifier static returnType nameOfMethod (type parameter1, type parameter2, ...) {
  // method body
}

Tip

• returnType - It specifies what type of value a method returns For example if a method has an int return type then it returns an integer value.
• methodName - It is an identifier that is used to refer to the particular method in a program
• modifier - It defines access types whether the method is public, private, and so on. To learn more, visit Java - Access Modifier
• parameter1/parameter2 - These are values passed to a method. We can pass any number of arguments to a method.
• static - If we use the static keyword, it can be accessed without creating objects.
  • For example, the sqrt() method of standard Java Math class is static. Hence, we can directly call Math.sqrt() without creating an instance of Math class.

oss

• If the method does not return a value, its returnType is void.
• il modifier di metodo è tipicamente pubblico, ovvero visibile a tutti
