To break down complex tasks into smaller, manageable, and reusable components, improving code organization and maintainability.

Utility functions like `Math.random()` or helper methods in a class that don't depend on object state.

To handle events like button clicks or menu selections, performing actions without returning a value.

To perform calculations or transformations on data and return the result, such as calculating the average of a list of numbers.

To define the actions and behaviors of game objects, such as moving a character or firing a weapon.

To handle user input, process data, and generate dynamic content on web pages.

To implement the functionality of app features, such as displaying data, handling user interactions, and managing device resources.

To perform operations on database records, such as inserting, updating, deleting, and querying data.

To implement mathematical algorithms and simulations, such as solving equations or modeling physical phenomena.

To implement machine learning algorithms, such as training models, making predictions, and evaluating performance.

It indicates that the method does not return a value.

Use the class name and dot notation: `ClassName.methodName();`

Use the object name and dot notation: `objectName.methodName();`

It's crucial for the compiler to identify and call the correct method.

The program jumps to the method's code, executes it, and returns to the point where it was called.

Organizing code into reusable blocks and making programs more modular.

They allow methods to accept input values, modifying their behavior.

The method name and the parameter list.

They belong to the class and act as general tools for any object of the class.

They operate on a specific object, with each object having its own version.

A block of code that performs a specific task.

A method that performs an action but does not return a value.

A method that performs an action and returns a value.

A method that belongs to the class itself, not to any specific object.

A method that operates on a specific object.

The method name and the parameter list (types and names of inputs).

Input values that a method can accept to modify its behavior.

The way to call methods using the class/object name, a dot, and the method name.

To organize code into reusable blocks, making programs more modular and easier to manage.

The actions an object can perform.
