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.
