1. Create an object of the class (if the method is non-static). 2. Use dot notation: objectName.methodName(parameters); or ClassName.methodName(parameters); for static methods.

1. Declare the method signature (access modifier, return type, method name, parameters). 2. Write the method body (the code that performs the task).

1. Create an object of the class (if non-static). 2. Use dot notation: objectName.methodName(parameters); or ClassName.methodName(parameters); for static methods. No return value is assigned.

1. Create an object of the class (if non-static). 2. Use dot notation: objectName.methodName(parameters); or ClassName.methodName(parameters); for static methods. 3. Store or use the return value.

1. Declare the class using the class keyword. 2. Define instance variables (attributes). 3. Define methods (behaviors). 4. Optionally, define constructors to initialize objects.

1. Write the Java code in a .java file. 2. Compile the code using javac YourFile.java. 3. Run the compiled code using java YourFile.

1. Declare a variable of the class type. 2. Use the new keyword followed by the class constructor to create a new object. 3. Assign the new object to the variable.

1. Specify the data type. 2. Provide a name for the variable. 3. Optionally, initialize the variable with a value. Example: int age = 25;

1. Write the if keyword followed by a boolean expression in parentheses. 2. Write the code to be executed if the expression is true within curly braces. 3. Optionally, add else or else if blocks for alternative conditions.

1. Write the for keyword followed by initialization, condition, and increment/decrement statements in parentheses. 2. Write the code to be executed in each iteration within curly braces.

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.

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.
