Study Notes

Java Basics

Key difference between an applet and an application in Java: an applet is a small program that runs in a web browser, while an application is a standalone program.

Java Tools

The Applet Viewer in Java is used to test and run applets in a controlled environment.
Javac is the Java compiler that converts Java source code into an intermediate form, called bytecode.
Java Interpreter (also known as JVM, Java Virtual Machine) is responsible for executing the bytecode generated by Javac.

Applet Limitations

An applet uses the Java Virtual Machine (JVM) for the execution of the code.
An applet cannot perform certain file operations on the local computer, such as writing to the local file system, due to security restrictions.
A limitation of an applet in terms of network communication is that it can only connect back to the server it was downloaded from.

Other Java Tools

The Java Disassembler (javap) is a tool that reverses the compilation process, generating a Java source file from a .class file.
Javah is a tool used in the Java development process to generate C header and stub files, allowing Java code to call native methods.
