Compilation in java

In Java, the process of translating legible Java source code into bytecode, or machine code, is referred to as compilation. The Java Virtual Machine (JVM) interprets this bytecode at runtime. It is not immediately performed by the hardware of the machine. The following steps are involved in the compilation process.

Writing source code for Java.

• Using a text editor or an Integrated Development Environment (IDE) like Eclipse, intellij IDEA, or Visual Studio Code, you should first write your Java program.

Saving the Source Code.

• The Source Code being saved, use the.java extension when saving your Java source code. The public class name defined in the source code should be reflected in the filename.

Compiling the Source Code.

• Compiling the Source Code, the source code is converted into bytecode using the Java compiler (javac). Run the following command after opening a terminal or command prompt, going to the directory where your.java file is located, and selecting it.
• If your code is error-free, the compiler will create one or more. Class files that contain the bytecode, javac yourfilename.java.

Bytecode Generation.

• The Java compiler converts your Java source code into bytecode, which is known as bytecode generation. Your code is represented as bytecode, a low-level format that is enhanced for the JVM.

Bytecode Execution.

• When you use the java command to launch a Java program, the JVM interprets the program’s bytecode and runs it. The JVM is in charge of memory management, addressing errors, and guaranteeing platform independence.

Just-In-Time Compilation (JIT).

• JIT, or just-in-time compilation. Many contemporary jvms additionally use Just-In-Time (JIT) compilation in addition to interpretation. This implies that just before to execution, the JVM may transform bytecode into machine code, which can enhance performance by lowering the overhead of repeated interpretation.
