Method calls and Invocation

[Akirien]

Hello there.. I have these questions taken from Intro To Java Programming by Y.Daniel Liang. I don't understand the question. Hope you will help me.

Write method calls/method invocation for the following method definition:

i. public void x (int y) {}

ii. public int a () {return 100}

iii. public double b(double c) {return 3.14}

iv. public char d (String e) {return 'X'}

v. public double cgpa (char grade) {return 3.9}

vi. public int m (double n, char p) {return 0}

If there are any questions or problems you have for each statement, please post them.
Try doing what the question asks and post your code here with any error messages you get.
Take them one at a time so there aren't too many error messages. Maybe after you write a couple you will see how its done.
