Convert infix to postfix, and evaluate postfix using custom Stack created using a singly linked list. This is only supposed to use THAT method, calling a normal Stack will give me a zero. I do have the conversion to postfix, but there may be error in there. But the main problem currently is the evaluation of postfix. I keep getting an error that I made for an empty stack, which I will include. For testing it is only supposed to...

Assume that you have a String "name" attribute in a Java class definition. Write a public method to return this "name" attribute. public String getName() { return name; } 1.) Write a statement that throws an IllegalArgumentException with the error message “Argument cannot be negative”. 2.) The method getValueFromFile is public and returns an int. It accepts no arguments. The method is capable of throwing an IOException and a FileNotFoundException. Write the header for this method.

File Factorials.java contains a program that calls the factorial method of the MathUtils class to compute the factorials of integers entered by the user. In this program, two things can possibly occur: The program always returns 1 if negative integers are entered by the user. Returning 1 as the factorial of any negative integer is not correct. The program also returns negative numbers when the user enters integers greater than 16. Returning a negative number for values over 16 also...
