I cant seem to figure out how to change this to using a char input instead of an int. Can someone please help with this ?

I have made a basic stack class utilizing a linked list for data storage and \$O(1)\$ push and pop and just want some basic feedback on the class to see if there is anything basic I missed. It seems to be working perfectly and I know there are no memory leaks. I'm just being cautious and wonderin...

Question: Root to leaf path sum equal to a given number
Given a binary tree and a number, return true if the tree has a root-to-leaf path such that adding up all the values along the path equals the given number. Return false if no such path can be found.

This following code executes correctly.I was wondering if there are better ways to write this code instead of using while(true) and break.For example using expressions,flags, do-while,etc.

I have created a simple system to get hands on experience with OOPS design and some features in java.

A Student can be a PartTimeStudent or FullTimeStudent
A score is valid only if it is between 20 and 100 ...

I would love my component to be reviewed. I am looking forward to responses mainly answering the questions:
Is my code violating the SOLID principals? If so, where and how?
Does my component contain any flaws?
Does my code contain any security issues?
Does my code follow the OOP principals?

I just finished my first PyGame project here (GitHub), and would like to get some reviews on the code.
It's multiple files of code and few images for graphics, so I figured it's easier if I just link the GitHub project. Let me know if you guys prefer pasting huge amounts of code here directly!

I (rather hastily) put together a class that can convert to and fro from Roman Numerals and Decimals. I would appreciate critical points on everything, especially:
Shortening my code.
Choosing a better approach.
Using better/new features of Java 8.
And so on...
I didn't bother to add JavaDoc...
Problem here.
It's not exactly the brute force approach but I'm not using any sort of pre-calculated primes table, and I'm definitely not using the coprimality trick shown in the PE pdf. I'm finding the divisor count for each triangle number via its representation as a product of primes. More on...
I was thinking a bit and came up with an interesting problem, suppose we have a configuration (input) file with:
x -> x + 1
x -> x * 2
x -> x * x
x -> -x
And furthermore we have a list of Integers:
List<Integer> list = new ArrayList<>();
list.addAll(Arrays.toList(1, 2, 3, 4, 5));

The temporary.put calls might be better by starting from static array and use a loop to put items.
