Question
Explain the use of the following JVM environment tools. [3 marks]i) Javacii) Javaiii) Appletviewer
Solution
i) Javac: This is the Java compiler tool that translates source code written in Java to Java bytecode. The process involves taking the .java file as input and outputting a .class file which contains the bytecode. This bytecode is what is run on the Java Virtual Machine (JVM).
ii) Java: This is the Java interpreter tool. It takes the Java bytecode (usually found in .class files) and interprets it to be run on the Java Virtual Machine (JVM). The Java tool can also be used to launch Java applications.
iii) Appletviewer: This tool is used to run and debug Java applets without a web browser. It is useful for developers who are creating applets and want to test them quickly without having to load them into a web page. The appletviewer tool takes an HTML file as input, and it displays all the applets that are included in the file.

The idea behind Java’s creation was revolutionary. At that time, most languages were compiled to platform-specific machine code. In contrast, Java is compiled into bytecode that runs on the Java Virtual Machine (JVM), a software-based engine that translates the bytecode into machine code at runtime. This key feature allows Java programs to be written once and run anywhere, a concept abbreviated as WORA. It eradicated the hefty task of rewriting code for different platforms, making software development more streamlined and efficient.
