Question 1.
Define method overloading.
Show hintHide hint
Think of different parameters for the same method.
Question 2.
What does the compiler use to resolve overloaded methods?
Show hintHide hint
Recall that the method signature includes the method name and parameters.
3Question 3.
What is method overloading?
- It is a feature allowing a method to have multiple names.
- It allows methods to have the same name with different parameters.
- It's a way to define generic methods.
Show hintHide hint
Recall the concept of multiple signatures for the same method name.
4Question 4.
True or False: Method overloading is resolved at runtime.
- True
- False
Show hintHide hint
Think about when the method calls are evaluated.
Question 5.
Create a Calculator class that overloads 'multiply' for different data types – int, double, String (to concatenate strings as well).
Show hintHide hint
Consider the operations for each type and their return values.
Question 6.
Discuss potential errors when method overloading is attempted with conflicting data types, like Integer vs. Double.
Show hintHide hint
Think about how method signature resolution works with implicit casting.
