yes we can run java program without using main. we can run program by declaring the variable static..
Java program without mainWe need a main method for executing a program.But YES we can write a program without using main() method.TRICK 1 of 2 :: while writing applets in java we don't use main... we use init() method instead.TRICK 2 of 2 :: using 'static' we can write a program whic will execute successfully and output the desired message on screen. Here it is :: class Mohit{ static { System.out.println("This java program has run without the main method"); System.exit(0); } } -->save the program as Mohit.java to compile::javac Mohit.java (in command prompt) to run ::java Mohit(command prompt) output will be ::This java program has run without the main methodWhoa!!!!! we are done.;)
The Main method is the method in which execution to any java program begins. A main method declaration looks as follows: public static void main(String args[]){ } The method is public because it be accessible to the JVM to begin execution of the program. It is Static because it be available for execution without an object instance. you may know that you need an object instance to invoke any method. So you cannot begin execution of a class without its object if the main method was not static. It returns only a void because, once the main method execution is over, the program terminates. So there can be no data that can be returned by the Main method The last parameter is String args[]. This is used to signify that the user may opt to enter parameters to the java program at command line. We can use both String[] args or String args[]. The Java compiler would accept both forms.
without class non of the folder can run so the java program should start in class we can use the class without object in java
Because, the main method is the starting point of the java program and if we need an object of that class even before the main can be invoked, it is not possible. Hence it is declared static so that the JVM Can acess the main method without having to instantiate that particular class
The Java main method of a program is the place where the program execution begins. A main method would look like below public static void main(String[] args){ }

In java need main() method. without main() in java we won't run the java programe main() signals the entry point to the program - it tells the Java Virtual Machine which is the first program that should be executed.
Nothing will happen. There is no restriction that every Java class must have a main method. The only program is that, this class cannot be executed as a standalone java program.

The program Java can be downloaded from the official Java website on the internet. The program is free for personal use, so it can be downloaded without any cost by anyone.

no
The main method is the first method, which the Java Virtual Machine executes. When you execute a class with the Java interpreter, the runtime system starts by calling the class's main() method. Themain() method then calls all the other methods required to run your application. It can be said that the main method is the entry point in the Java program and java program can't run without this method.The signature of main() method looks like this:public static void main(String args[])The method signature for the main() method contains three modifiers:public indicates that the main() method can be called by any object.static indicates that the main() method is a class method.void indicates that the main() method has no return value.
Java's List interface defines the size() method, which can be used to retrieve the length of a list.
The Java main method of a program is the place where the program execution begins. A main method would look like below public static void main(String[] args){ }
The main method is simply an entry point to your executable code. When you run a Java program, it looks for a main method as the first section of code to execute, which is why all of your programs start there.
