Is main method compulsory in Java?
Yes, it is required for any executable program.
If you try to execute a Java class, the JVM will look for a main method to invoke it.
Not all classes need a main , only the one that serve as “entry point” for execution..
How can I print hello without main method?
Java Program to Print any Statement Without Using the Main Methodpublic class Without_Main.System. out. println(“Hello World!!”);System. exit(0);//Does not work with JDK7.
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 override private method in Java?
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 inherit private method in Java?
You can only call a private member method in its definition class. … say() because derived classes can’t inherit private methods from its base class. Only protected and public methods/variables can be inherited and/or overridden.
Can we create a program without main method in Java?
A Java program can run without the main method. You need a static block for that, and You need to put your executable code in that static block and execute it.
Can you override 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.
Why we Cannot override static method?
Static methods cannot be overridden because they are not dispatched on the object instance at runtime. The compiler decides which method gets called. Static methods can be overloaded (meaning that you can have the same method name for several methods as long as they have different parameter types).
Can you make a constructor final?
No, a constructor can’t be made final. A final method cannot be overridden by any subclasses. As mentioned previously, the final modifier prevents a method from being modified in a subclass. … In other words, constructors cannot be inherited in Java therefore, there is no need to write final before constructors.
What does string  args mean?
The String args parameter is an array of Strings passed as parameters when you are running your application through command line in the OS. … String args means an array of sequence of characters (Strings) that are passed to the “main” function. This happens when a program is executed.
Can we have 2 main methods in Java?
The answer is no; there can only one “main” method – where “main” means an entry point you can “run”. You can code overloaded versions as in your example, but they can’t be “run”. There can be more than one main method in a single program. But JVM will always calls String argument main() method.
Can we override static method?
Can we Override static methods in java? We can declare static methods with the same signature in the subclass, but it is not considered overriding as there won’t be any run-time polymorphism. Hence the answer is ‘No’.
