Which of the following are not valid overloaded methods?
i. public void somemethod(int number1) public void somemethod(string number3) public int somemethod(int number2)
ii. public int somemethod(int number1) public double somemethod() public string somemethod(string number3)
iii. public void somemethod() public double somemethod(double number1) public double somemethod()

statement i only.
statement ii only.
statement iii only.
statements i and iii only.
statements ii and iii only.

Statement I and III only

Explanation:

Firstly what is method overloading in programming in general. Method overloading is the process of having more than one method bearing the same name in a class. Java for example is a programming language that has no problem with method overloading if some conditions are met.

For method overloading to be used the arguments that each method with the same must require must be different.

Java for example uses the argument used with the method  to determine which of the identical methods (that is methods with the same) is being referred to by the USER.

So if two methods with similar names also require arguments of the same type like in Statement I where two methods require an "int" type argument the programming language will be unable to know the method to implement.

Similarly in Statement III two methods require no argument which is also a type of arguments, the programming language will be unable to decide which of the methods to implement.

Finally, Statement II contains three methods each with requiring a different type of argument, this explicitly separates the method for the programmming language and helps to identify the right one to implement.
