Core Java Programming Course- Method Overloading

The video tutorial explains the concept of method overloading in Java, highlighting its importance in interviews. It covers the rules for overloading methods, such as differing in data type, number, or order of arguments. Examples demonstrate how to create overloaded methods with different argument types. The tutorial also explains how Java determines which overloaded method to execute based on argument types and addresses common mistakes, emphasizing that argument names do not affect overloading.

What is the primary focus of this session on Java?

• Class inheritance

• Method overloading

• Method overriding

• Data encapsulation

Which of the following is a valid reason for method overloading?

• Changing the method visibility

• Changing the method name

• Changing the return type

• Changing the number of arguments

In method overloading, which aspect is NOT considered for differentiating methods?

• Order of arguments

• Data type of arguments

• Number of arguments

• Name of arguments

How does Java decide which overloaded method to execute?

• By the method name

• By the return type

• By the argument types and order

• By the argument names

What happens if two overloaded methods have the same argument types but different argument names?

• Java will execute both methods

• Java will throw a compile-time error

• Java will ignore the argument names

• Java will choose the first method

Which of the following is NOT a valid method overloading scenario?

• Two methods with different argument types

• Two methods with different argument orders

• Two methods with different argument names

• Two methods with different number of arguments

Why is it important to have different data types for overloaded methods?

• To avoid confusion during method execution

• To ensure methods have unique names

• To allow methods to return different types

• To prevent runtime errors
