Program Plan Intro
Compiler:
In
- Complier completely reads the program once and compiles the entire code.
- The complier displays all warnings and errors.
- If the program does not contain any error, the source code will be translated into byte code.
- Java Compiler is the tool, which is used to compile Java programs, and the command that is used for compilation is “javac”.
Explanation of Solution
b. Contents of the file:
The compiler translates the Java source code into byte code. The extension of Java source code program is ".java" and the extension of java byte code program is ".class"...
Explanation of Solution
c. Run the program:
The compiler translates the Java source code into byte code. The extension of Java source code program is ".java" and the extension of java byte code program is ".class".
Java Bytecode program runs on any machine that has a JVM (Java Virtual Machine) interpreter.
- The JVM (Java Virtual Machine) interpreter is designed to execute the bytecode program produced by the compiler...

Question3: (30 MARKS) Passenger Rail Agency for South Africa Train Scheduling System Problem Statement Design and implement a train scheduling system for Prasa railway network. The system should handle the following functionalities: 1. Scheduling trains: Allow the addition of train schedules, ensuring that no two trains use the same platform at the same time at any station. 2. Dynamic updates: Enable adding new train schedules and canceling existing ones. 3. Real-time simulation: Use multithreading to simulate the operation of trains (e.g., arriving, departing). 4. Data management: Use ArrayList to manage train schedules and platform assignments. Requirements 1. Add Train Schedule, Cancel Scheduled Train, View Train Schedules and Platform Management 2. Concurrency Handling with Multithreading i.e Use threads to simulate train operations,...
