Particle Simulator

This is a simple particle simulator implemented in Java. It uses Swing for the graphical user interface and Java's built-in concurrency utilities for the simulation logic.

How to run the program

• Open the jar file in the src directory, two windows should pop-up (canvas + inputs)

• Click on the dropdown to change input type Single Particle, Constant Velocity + Varying Angle, Constant Start Points + Varying Angle, Constant Start Points + Varying Velocity, Add Wall

  • As for all types, simply input the required fields (X, Y, angle, velocity, etc.)
  • Click on the Add button after completing the inputs

• Clear all of the Particles by clicking on the Clear Particles button

• Clear all of the Walls by clicking on the Clear Walls button

• Close either of the windows to stop the program

For Developers

Prerequisites

• Java Development Kit (JDK) 8 or later

Compiling the Program

1. Open a terminal/command prompt.
2. Navigate to the directory containing the src folder.
3. Compile the Java files using the javac command:

javac src/*.java

This will compile all the Java files in the src directory and create corresponding .class files.

Running the Program

After compiling the program, you can run it using the java command. The main class of the program is ParticleSimulator.

java src/ParticleSimulator

This will start the particle simulator. You can interact with the program using the graphical user interface.

Creating a JAR File

1. After compiling the program, navigate to the src directory:

cd src

2. Create a manifest file named Manifest.txt with the following content:

Main-Class: ParticleSimulator

Note the extra newline at the end of the file.

This tells the JAR file which class to run when it's executed.

3. Create the JAR file using the jar command:

jar cvfm ParticleSimulator.jar Manifest.txt *.class

This will create a JAR file named ParticleSimulator.jar that includes all the .class files in the current directory and uses the manifest file you created.

Running the JAR File

After creating the JAR file, you can run it using the java command:

java -jar ParticleSimulator.jar

This will start the particle simulator just like before, but now you're running it from a single JAR file instead of multiple .class files.

Features

• Add particles with fixed velocity and angle.
• Add particles with a fixed start point and varying angle.
• Add particles with a fixed start point and varying velocity.
• Add walls for the particles to bounce off.
• Clear all particles or walls.
