This is an Algorithm Simulator coded in Java as my Design Analysis and Algorithm Project (2nd Year). It simulates Selection Sort and Insertion sort using animations which are written from scratch using java threads. It also supports both Ascending and Descending sorting.

Student Information System (Github Project) This system is developed in Java and mySQL as a group project by me and 3 other members during a period of 1 month. The system allows the administrator to,  enroll students to the system  update enroll information  add/update course and degree program details  generate reports  create exams and edit relevant information  calculate gpa of the relevant exam  assign lecturers to courses  add lecturers/update details Lecturers to,  assign course grades  view their feedback  generate reports  view student / course / degree program details Students to,  view their profile  view their grading information  give feedback to lecturers   view lecturer / course / degree program details and other features. Below are some interfaces of the project. (Splash Screen) (Login) (Admin View) (Student Registration) (Update Student Record) (Add Exam) ` (Assign Gr
