Question

Discuss the 3 major steps when writing and running program in Java

Answer 1

To write and run a program in Java, one must write the code, compile it into bytecode, and then run the program using the Java Virtual Machine.

Step-by-step explanation:

The Three Major Steps of Writing and Running a Program in Java

Writing and running a program in Java involves several steps, but the three major ones are as follows:

1. Writing the Code: The first step is to write the source code using a text editor or an Integrated Development Environment (IDE). This code is written in the Java programming language and contains the set of instructions that the computer will execute.
2. Compiling the Code: Once the code is written, the next step is to compile it. This process translates the human-readable Java code into bytecode that the Java Virtual Machine (JVM) can understand and execute. This is done using the Java compiler, 'javac'.
3. Running the Program: After compilation, the bytecode can be run on any platform that has a JVM. This is typically done using the 'java' command followed by the name of the class containing the 'main' method, which is the entry point of the program.

By following these steps, Java developers can write, compile, and execute their programs, creating applications that can run on a variety of platforms.
