The students are studying for a degree (such as BA, M.Sc., etc.) within the framework of the modular system. The college provides a number of modules, each being characterized by its code, title, and credit value, module leader, teaching

An exception is an abnormal condition that arises in a code sequence at run time. Java provides powerful features for exception handling. Although Javas builtin exceptions handle most common exceptions, you will probably want to create your own exception types to handle situations specific to your applications. This is quite easy to do just define

Consider a closed vessel initially containing 1 mol of tetrahydrofuran at 50C and 52 kPa. Imagine that pure chloroform is slowly added at constant temperature and pressure until the vessel contains 1 mol tetrahydrofuran and 9 mol chloroform. Describe the evolution of phases and phase compositions during this process. Comment on the practical

Assume that you have created a mechanical arm that can hold a pen. The arm can perform the following tasks: Lower the pen to a piece of paper. Raise the pen from the paper. Move the pen 1 inch along a straight line. (If the pen is lowered, this action draws a 1-inch line from left to right; if the pen is raised, this action just repositions the

Object-Oriented Design and Programming Programming Assignment 2 - Mini Twitter Problem Description In this programming assignment, you will build a Java-based Mini Twitter with graphical user interface (GUI) using Java Swing. This is going to be a pure desktop program, without web or mobile components. The goal of this assignment is to let you

Grades are mapped to a grade point as follows: A:10, B:8, C:6, D:4 and F:0. Create a table to store these mappings and write a query to find the CPI of each student, using this table. Make sure students who have not got a non-null grade in any course are displayed with a CPI of null.

Part 3 Coding Exercise Decoding a Message from a Text File In this exercise, you will develop a function named decode(message file). This function should read an encoded message from a .txt file and return its decoded version as a string. Note that you can write your code using any language and IDE you want (Python is preferred if possible, but
