   Jan 27, 2023 · Welcome to Geeks. Let us understand the real compilation and execution process. Step 1: Let us create a file writing simple printing code in a text file and saving it with “.java” extension. Step 2: Open the terminal (here we are using macOS)and go to the Desktop directory using the below command as follows.

   Apr 7, 2013 · 2. The main method is the entry point to your program. If the class that contains the "main" method has static members that need to be initialized or a static code block, this will be executed BEFORE the "main" method. Look at this sample code: public class Test {. private static Object obj = new Object();

   Sep 21, 2021 · Java's main() method is the starting point from where the JVM starts the execution of a Java program. JVM will not execute the code, if the program is missing the main method. Hence, it is one of the most important methods of Java, and having a proper understanding of it is very important. The Java compiler or JVM looks for the main method when it

   Oct 20, 2022 · Execution Lifecycle. The execution lifecycle of a Java application can be broadly divided into three phases: Compilation: The source code of the application is converted into bytecode 1 using the “javac” compiler. Class Loading: The bytecode is loaded into memory and the necessary class files are prepared for execution.

   java fileName: After successfully compiling a Java source file with javac, you can run the compiled bytecode with the java command. In this case, "fileName" should be replaced with the name of the class containing the public static void main (String [] args) method. This is the entry point of your Java program.

   When does execution start in a Java program?

   • I said in viva that execution starts from static block in a java program. The static blocks are executed when the class is initialized. For the class containing main method it will be before calling this method, because class has to be initialized before any of it's method is used.

   What is execution phase in Java?

   • This step maps the optimized intermediate code to bytecode instructions, encapsulating the essence of the original source code while accommodating the idiosyncrasies of the JVM. The execution phase takes place when you run your Java program.

   Does execution start from a static block in a Java program?

   • I said in viva that execution starts from static block in a java program. You are right if the static code is part of the class that contains the "main" method. This is the only case that you're right that I can think of. If the answer was satisfying, please accept it (and you can also vote-up). Thanks! This is the start method of a java program:

   How do I start a Java application without a main method?

   • A Java application will be normally initialised by the main method: System.out.println("Executing my application..."); The static block will be executed when the JVM loads the class. You cannot start your application without a main method or the JVM will appear an error message.
