No, all classes MUST have a main method.
We can't call a class. We always call a method in java.
No, main() class is required to execute the program as that's the starting point of the program.
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.
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 driver class is often the class that contains the "Main" method.
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
Yes. Every Java class can have a main method
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.
You cannot do that. The main method of a java class is the point where the execution begins. You can print messages only after a main method is invoked.
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.
No. It is a user defined function which the person who is creating the java class has to code by himself.
no
