Understanding Method Overloading

What is the definition of method overloading?

• Method overloading is the process of overriding a method in a subclass.

• Method overloading refers to defining methods with different names in a class.

• Method overloading is the ability to define multiple methods with the same name but different parameter lists in a class.

• Method overloading is the ability to change the return type of a method without changing its name.

How does method overloading differ from method overriding?

• Method overloading is about multiple methods with the same name but different parameters; method overriding is about redefining a superclass method in a subclass.

• Method overloading requires the same number of parameters; method overriding does not involve inheritance.

• Method overloading changes the return type of a method; method overriding does not affect the method signature.

• Method overloading is used for private methods only; method overriding is for public methods.

In Java, what is required for two methods to be considered overloaded?

• Methods must have the same name but different parameter lists.

• Methods must have different return types but the same parameter lists.

• Methods can have the same name and parameter types.

• Methods must have different names but the same parameter types.

Can method overloading occur in the same class?

• No, method overloading can only occur in subclasses.

• Yes, but only if the methods have the same name and return type.

• Yes, method overloading can occur in the same class.

• No, method overloading is not allowed in any class.

What is an example of method overloading with different parameter types in Java?

• public void display(String text) { System.out.println(text); }

• public void display() { System.out.println("No parameters"); }

• public void display(int number, String text) { System.out.println(number + text); }

• public void display(int number) { System.out.println("Integer: " + number); } public void display(double number) { System.out.println("Double: " + number); }

How does method overloading improve code readability?

• Method overloading makes code execution faster by optimizing function calls.

• Method overloading improves code readability by allowing the use of the same function name for similar operations, making the code more intuitive and easier to understand.

• Method overloading reduces the number of functions needed in a program.

• Method overloading eliminates the need for comments in the code.

Can you overload a method by changing the return type only?

• You can overload a method by changing the parameter types only.

• Overloading is possible by changing the method name and return type.

• No, you cannot overload a method by changing the return type only.

• Yes, you can overload a method by changing the return type only.

What is a real-world example of method overloading?

• A 'print' method that accepts different data types (string, integer, list) in a class.

• A 'save' method that writes data to a file without parameters.

• A 'display' method that shows a fixed message regardless of input.

• A 'calculate' method that only adds two integers.

How does method overloading relate to polymorphism in Java?

• Method overloading is a form of compile-time polymorphism in Java.

• Method overloading is a type of inheritance in Java.

• Method overloading is unrelated to polymorphism in Java.

• Method overloading is a form of runtime polymorphism in Java.

What happens if you try to overload methods with the same name and parameters?

• The method is ignored and not executed.

• A compilation error occurs due to ambiguous method definitions.

• The program runs successfully without any issues.

• The method is automatically overridden without errors.
