Can we write main method without static in Java?

You can write the main method in your program without the static modifier, the program gets compiled without compilation errors. But, at the time of execution JVM does not consider this new method (without static) as the entry point of the program.

What if main method is not static in Java?

Static method of a class can be called by using the class name only without creating an object of a class. The main() method in Java must be declared public, static and void. If any of these are missing, the Java program will compile but a runtime error will be thrown.

What happens if I remove static from main method?

1 Answer. If you don't add the 'static' modifier in your main method definition, the compilation of the program will go through without any issues but when you'll try to execute it, a "NoSuchMethodError" error will be thrown.

What happens if the main () isn't declared as static?

Bootstrap class loader searches for main function in the class file, if main function is not declared as static, it will trough an error because declaring function as static allows it to be called without instantiating that class file where the main function is.

Can we write main method without void?

Yes. Things like libraries don't have a main method. The main method is the entry point for the program, so you'll have to have a main method somewhere or the code won't execute, but not necessarily in any given Java file.

Can I write main method without static?

You can write the main method in your program without the static modifier, the program gets compiled without compilation errors. But, at the time of execution JVM does not consider this new method (without static) as the entry point of the program.

Is the main method static?

The main() method is static so that JVM can invoke it without instantiating the class. This also saves the unnecessary wastage of memory which would have been used by the object declared only for calling the main() method by the JVM.

Can main method be final?

Yes, we can declare the main () method as final in Java. The compiler does not throw any error. If we declare any method as final by placing the final keyword then that method becomes the final method. The main use of the final method in Java is they are not overridden.

Can we overload main method?

Yes, we can overload the main method in Java, but When we execute the class JVM starts execution with public static void main(String[] args) method.

What is need static before main method?

Before the main method is called, no objects are instantiated. Having the static keyword means the method can be called without creating any objects first.

Can we write method without class in Java?

No you cannot make a java program without class! Because without a class you cannot make objects!

Why do we use static before main in Java?

Java program's main method has to be declared static because keyword static allows main to be called without creating an object of the class in which the main method is defined. If we omit static keyword before main Java program will successfully compile but it won't execute.

Why main method is void in Java?

Java main method doesn't return anything, that's why it's return type is void . This has been done to keep things simple because once the main method is finished executing, java program terminates. So there is no point in returning anything, there is nothing that can be done for the returned object by JVM.

Why main method is always public in Java?

Why is main method public in Java? We know that anyone can access/invoke a method having public access specifier. The main method is public in Java because it has to be invoked by the JVM. So, if main() is not public in Java, the JVM won't call it.

Can we have 2 main methods in Java?

From the above program, we can say that Java can have multiple main methods but with the concept of overloading. There should be only one main method with parameter as string[ ] arg.

Can we execute a class without a main method?

Yes, we can execute a java program without a main method by using a static block. Static block in Java is a group of statements that gets executed only once when the class is loaded into the memory by Java ClassLoader, It is also known as a static initialization block.

Can we declare main method as private?

Yes, we can declare the main method as private in Java. It compiles successfully without any errors but at the runtime, it says that the main method is not public.

Can main method be abstract?

Yes, you can use the main() method in abstract class. The main() method is a static method so it is associated with Class, not with object or instance. The abstract is applicable to the object so there is no problem if it contains the main method.

Can we write main method in subclass?

Yes. If you run it, It'll execute parent class' main method. The static method will'be inherited but can't be overriden. If you define any static method with same name in subclass it'll only hide the parent method not override it.

Why main method is overloaded?

Yes, main method can be overloaded. Overloaded main method has to be called from inside the "public static void main(String args[])" as this is the entry point when the class is launched by the JVM. Also overloaded main method can have any qualifier as a normal method have. Show activity on this post.

Can we override a main method in Java?

No, we cannot override main method of java because a static method cannot be overridden. The static method in java is associated with class whereas the non-static method is associated with an object.

Who calls main method in Java?

2. main() method in java is always called by JVM (Java Virtual Machine) before any objects are created.

Can we override static method?

Overloading is the mechanism of binding the method call with the method body dynamically based on the parameters passed to the method call. Static methods are bonded at compile time using static binding. Therefore, we cannot override static methods in Java.

Can we call non-static method in static method?

Solution 1. A static method provides NO reference to an instance of its class (it is a class method) hence, no, you cannot call a non-static method inside a static one. Create an object of the class inside the static method and then call the non-static method using such an object.

How do you make a non-static method?
