double click on it, a program editor will be open, erase the code and type your program coding. How you create, compile and execute a program in Java or BlueJ? Explain your answer?Īns: Create: Click on new class button from BlueJ editor, then type the class name a program icon will be created. It is an IDE (Integrated Development Environment), which includes an editor a debugger and a viewer. Open Product.Īns: BlueJ is a Java development environment. Write the five characteristics of Java/BlueJ?Īns: 1. Actually this Java interpreter is known as Java Virtual Machine (JVM).Īns: The Java development kit comes with a collection of tools that are used for developing and running java programs.Īns: The Java APIs (Application Program Interface) consist of libraries of pre-compiled code that programmers can use in their application. Programs written in Java are compiled into Java byte-code, which is then interpreted by a special java Interpreter for a specific platform. It hides the underlying OS from Java application. Instead of interacting with the Operating System directly, Java programs runs on a virtual machine provided by Java, therefore Java is often referred to as a platform also.Īns: Bytecode is a set of pseudo mechanic language instructions that are understood by the JVM (Java Virtual Machine) and are independent of the underlying hardware.Īns: JVM or Java Virtual Machine is an abstract machine designed to be implemented on top of existing processors. Why is Java often termed as a platform?Īns: Platform is the environment in which programs execute. but these questions are must be known by students.
