Methods in Programming

Which of the following best describes a method signature?

A class contains a private method. Which of the following statements is true regarding access to this method?

Which access specifier allows a method to be accessed from anywhere, including outside the class and its subclasses?

Consider a base class Animal and a derived class Dog that inherits from Animal. If a method in Animal is declared as protected, who can access this method?

Assume you are designing a class and want certain methods to only be used by the class itself, and not by any other class that inherits from it. Which access specifier should you use?

Which of the following is the most significant advantage of using methods in programming?

What does 'defining a method' primarily entail in the context of programming?

Consider the following method definition: public double calculateArea(int length, int width). Which statement is most accurate?

In what scenario would dividing a complex task into multiple methods be LEAST advantageous?

What is the primary role of a return statement in a function?

Which statement about the placement of a return statement within a method block is correct?

If a method does not return any value, what return type should be specified in the method header?

What is the purpose of the parameter list in a method definition?

What is the correct syntax for a return statement that returns the value of a variable result?

A function is designed to calculate the area of a rectangle. Which function name would be most appropriate?

Consider a function defined as int Multiply(int x, int y). What does int signify in this function definition?

Which type of function performs actions like input/output operations but does not return any output value?

Which characteristic is NOT a typical feature of a return statement in programming?

Consider a scenario where you need to return a value conditionally based on whether x is greater than y. How would you structure the return statements?

Why is placing executable statements after a return statement generally considered bad practice?

In Java, what happens if a method is defined with a return type (e.g., int, String) but does not include a return statement in every possible execution path?

What is the primary purpose of the return statement in the following code snippet?

int calculateSum(int a, int b) {
  int sum = a + b;
  return sum;
}

What is the term used to describe the process of utilizing a method within a program?

Which action represents the 'invocation' of a method?

Which programming concept is most closely related to the idea of 'invoking a method'?

What must be done before a method can be 'invoked' in a program?

What is the primary purpose of 'invoking' a method in programming?

In a method definition, what is the primary role of formal parameters?

Consider the code snippet: result = calculate(x, y); Which term accurately describes x and y in this context?

How do formal and actual parameters relate to each other during a method call?

In the context of method parameters, what is the significance of the order in which actual parameters are passed?

If a method multiply(int a, int b) is defined, and called with multiply(5, 10), which are the formal parameters?

Which of the following is true about a method declared as public void calculate()?

What does an empty parenthesis () signify in a method declaration?

Given the code snippet int x = 10; void modify(int x){ x = x + 5; }. What is the value of x after calling modify(x)?

Which of the following code blocks correctly calculates the factorial of a number n without returning any value?

If a method process() is defined with an empty parameter list and a void return type, which of the following actions can it perform?

What is the key distinction between 'pass by value' and 'pass by reference' when applied to method parameters in Java?

Consider the following scenario: A method receives an array as a parameter. Inside the method, the first element of the array is modified. What happens to the original array passed to the method?

In a 'pass by reference' context, what is the significance of the term 'alias'?

Given the following Java code:

class Test {
    void modifyArray(int arr[]) {
        arr[0] = 100;
    }

    public static void main(String[] args) {
        int myArray[] = {1, 2, 3};
        Test t = new Test();
        t.modifyArray(myArray);
        System.out.println(myArray[0]);
    }
}

What will be the output of this program?

Which of the following statements is NOT a characteristic of 'pass by reference'?

Which of the following statements best describes the core concept of polymorphism as it relates to function overloading?

What is the primary benefit of using function overloading, especially when performing similar operations?

Consider two methods with the same name in a class. Which of the following scenarios would invalidate function overloading?

Which term accurately describes the process by which the appropriate overloaded function is selected during compilation?

Which of the following method declarations would be a valid overload of the method int calculate(int x, double y)?

If a class contains the following two method declarations, what will happen when the code is compiled? int process(int a, double b); double process(int p, double q);

Which of the following scenarios benefits MOST from using function overloading?

Which of the following statements is true regarding function overloading and the concept of "best match"?
