Can we override and overload main method?
In short, the main method can be overloaded but cannot be overridden in Java. That's all about overloading and overriding the main method in Java. Now you know that it's possible to overload main in Java but it's not possible to override it, simply because it's a static method.Can we override the overloaded method?
So can you override an overloaded function? Yes, since the overloaded method is a completely different method in the eyes of the compiler.Can we override or overload main method in Java?
Overriding main methodYou cannot override static methods and since the public static void main() method is static we cannot override it.
Can we override and overload static methods?
No, we cannot override static methods because method overriding is based on dynamic binding at runtime and the static methods are bonded using static binding at compile time. So, we cannot override static methods.Can we overload the 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.Can we overload a main() method in Java? || Java Interview Question
Can we override private method?
No, we cannot override private or static methods in Java. Private methods in Java are not visible to any other class which limits their scope to the class in which they are declared.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 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 write static public void main String args?
Yes, we can change the order of public static void main() to static public void main() in Java, the compiler doesn't throw any compile-time or runtime error. In Java, we can declare access modifiers in any order, the method name comes last, the return type comes second to last and then after it's our choice.Can we declare main method as 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 override non static method in Java?
No, we cannot override non static method as static method in java.Why is 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 we make constructor static?
No, we cannot define a static constructor in Java, If we are trying to define a constructor with the static keyword a compile-time error will occur. In general, static means class level. A constructor will be used to assign initial values for the instance variables.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.Can we declare a class as static?
So, Yes, you can declare a class static in Java, provided the class is inside a top-level class. Such clauses are also known as nested classes and they can be declared static, but if you are thinking to make a top-level class static in Java, then it's not allowed.Can we execute a program without 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 constructor be overridden?
Constructor looks like method but it is not. It does not have a return type and its name is same as the class name. But, a constructor cannot be overridden. If you try to write a super class's constructor in the sub class compiler treats it as a method and expects a return type and generates a compile time error.Can default methods be overridden?
Overriding default methodsyou can override a default method of an interface from the implementing class.
Can we inherit main method in Java?
Can we override main method in java ? Short answer is NO, we can not override main method in java. Reason is very simple. As main method is static and we know very well that we can not override static methods in Java, hence main method could not be overridden.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 happens if we write main () inside main () method?
Well,you can call a main() within the main() function ,but you should have a condition that does not call the main() function to terminate the program. Otherwise,the program will never return and run infinitely. It will cause a stack overflow when the stack space is used up.Can abstract method override?
An abstract method is a method that is declared, but contains no implementation. you can override both abstract and normal methods inside an abstract class. only methods declared as final cannot be overridden.Can we extend static class?
Just like static members, a static nested class does not have access to the instance variables and methods of the outer class. You can extend static inner class with another inner class.Can we override protected method as public?
Yes, the protected method of a superclass can be overridden by a subclass. If the superclass method is protected, the subclass overridden method can have protected or public (but not default or private) which means the subclass overridden method can not have a weaker access specifier.Can we use void with constructor?
Note that the constructor name must match the class name, and it cannot have a return type (like void ). Also note that the constructor is called when the object is created.
