Java Beginners Tutorial in Tamil | Internal Working or Execution of Java Program in Tamil.....
Step 1: Writing the code in NetBeans IDE. As you can see in the diagram step 1 is to actually type the code. In this image above you can see we have our code file as abc.java
Step 2: Once you have written the code you save itand click Run (if you are using Netbeans IDE otherwise you compile the code in the command prompt by using the command javac abc.java). This invokes the Java Compiler. The compiler checks the code for syntax errors and any other compile time errors and if no error is found the compiler converts the java code into an intermediate code(abc.class file) known as bytecode. This intermediate code is platform independent (you can take this bytecode from a machine running windows and use it in any other machine running Linux or MacOS etc). Also this bytecode is an intermediate code, hence it is only understandable by the JVM and not the user or even the hardware /OS layer.
Step 3: This is the start of the Run Time phase, where the bytecode is loaded into the JVM by the class loader(another inbuilt program inside the JVM).
Step 4: Now the bytecode verifier(an inbuilt program inside the JVM) checks the bytecode for its integrity and if not issues are found passes it to the interpreter.
Step 5: Since java is both compiled and interpretted language, now the interpreter inside the JVM converts each line of the bytecode into executable machine code and passed it to the OS/Hardware i.e. the CPU to execute.
