20+ of the Most Interesting Projects Source Code in Java [2023]

Java Features

1. Platform Independence.

Java is a platform independent language becoz of the bytecode magic of java. In java when we execute the source code...it generates the .class file comprising the bytecodes. Bytecodes are easily interpreted by JVM which is available with every type of OS we install.

2. Object Oriented.

Object-oriented programming is a method of programming based on a hierarchy of classes, and well-defined and cooperating objects.

3. Robust.

java gives importance to memory management by using the technique called Garbage Collection and Exception handling.

4. Security

since java is used on internet, security is an important issue. A security code is asked before a java code is interpreted on internet.

5. MultiThreading and interactive

Multithreading means handling more than one job at a time. Java supports Multithreading.

Running a Java Project

Running a Java project involves compiling your Java code and executing it using the Java Virtual Machine (JVM). Here's a step-by-step guide on how to run a Java project:

1. Install Java Development Kit (JDK):

Download and install the latest version of JDK from the official Oracle or OpenJDK website.

2. Write Your Java Code:

Create a .java file containing your Java code using a text editor or an Integrated Development Environment (IDE) like Eclipse, IntelliJ IDEA, or Visual Studio Code.

3. Compile Java Code:

Open a command prompt or terminal. Navigate to the directory where your .java file is located. Compile your Java code using the javac command:

javac YourFileName.java

4. Run Java Program:

After compiling, run your Java program using the java command followed by the class name (without the .class extension):

java YourClassName

5. Classpath (if needed):

If your program uses external libraries or packages, you might need to include them in the classpath using the -classpath or -cp option:

java -classpath .;path/to/library YourClassName

Remember that the steps above apply to running Java projects locally on your computer. For more complex projects, you might need to consider build tools like Maven or Gradle to manage dependencies and automate the build process. Additionally, when deploying Java applications to production or distributing them, you would package them into executable JAR files or other suitable formats.

Last but not least, if you're just starting with Java, consider learning the basics of the language, object-oriented programming principles, and how to use development tools effectively.
