Method Declaration and Syntax in Java

Introduction​

Methods in Java are blocks of code that perform a specific task and can be called upon whenever needed. They help in organizing code, improving reusability, and making programs more modular and maintainable.

Method Declaration​

A method declaration in Java defines a method's name, return type, and parameters. Here's the basic syntax for declaring a method:

Syntax​

accessModifier returnType methodName(parameters) {
    // method body
}

Example​

public int add(int a, int b) {
    return a + b;
}

Explanation​

  • Access Modifier: Defines the visibility of the method. Common access modifiers include public, private, protected, and the default (package-private).
  • Return Type: Specifies the type of value the method returns. If the method does not return any value, use void.
  • Method Name: The name of the method. It should be a valid identifier and follow camelCase naming convention.
  • Parameters: A comma-separated list of input parameters. Each parameter consists of a data type and a variable name.
