Answer:

Three ways to overload a method

In order to overload a method, the argument lists of the methods must differ in either of these:

1. Number of parameters.

For example: This is a valid case of overloading

add(int, int)

add(int, int, int)

2. Data type of parameters.

For example:

add(int, int)

add(int, float)

3. Sequence of Data type of parameters.

For example:

add(int, float)

add(float, int)
