What is the process of dividing a large program into smaller, manageable, and reusable parts called?

• Compilation

• Debugging

• Modularization

• Execution

Which of the following is not an advantage of modular programming?

• Increased code reusability

• Improved program reliability

• More difficult collaboration among programmers

• Better abstraction and maintainability

What is the value that a method receives when it is called?

• Argument

• Parameter

• Return value

• Variable

When a method receives data as a parameter, what must be specified?

• Only the parameter name

• Only the parameter type

• Both the parameter type and name

• Neither the parameter type nor name

Which of the following is the correct way to call a method in Java?

• call methodName();

• methodName[]();

• methodName();

• invoke methodName();

When passing data as an argument in the method call, is it necessary to specify the data type?

• No, the data type is only specified when defining the method, not when calling it.

• Yes, the data type must be specified each time the method is called to ensure proper handling.

• Yes, the data type must match the return type of the method being called.

• No, the data type is automatically inferred when passing the argument in the method call.

What is the purpose of the return statement in a method?

• It prints the return value to the console.

• It pauses the method execution until additional input is provided.

• It defines the method’s input parameters.

• It ends the method execution and sends a value back to the calling method.

What does the void keyword indicate in a method declaration?

• The method will return a value of type void.

• The method does not return any value.

• The method will return a value of any type.

• The method is only used for debugging purposes.

What happens to a local variable after the method in which it is declared finishes executing?

• It remains available for other methods to use.

• It is saved globally and can be accessed by any part of the program.

• It ceases to exist and cannot be used outside the method.

• It becomes a parameter in other methods that are called afterward.

Why do we make external methods private in a program?

• To allow other classes to access and modify the method freely.

• To restrict access to the method and ensure it is only used within the class, maintaining encapsulation.

• To improve performance by limiting the method's functionality.

• To make the method accessible only to subclasses and prevent its use by other classes.
