Why is main method static?
Java main() method is always static, so that compiler can call it without the creation of an object or before the creation of an object of the class.
Static method of a class can be called by using the class name only without creating an object of a class..
Can we override public method?
If a method cannot be inherited, then it cannot be overridden. A subclass within the same package as the instance’s superclass can override any superclass method that is not declared private or final. A subclass in a different package can only override the non-final methods declared public or protected.
What is method overriding explain with example?
Method overriding, in object-oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes.
What does override mean?
to prevail or have dominance over; have final authority or say over; overrule: to override one’s advisers. to disregard, set aside, or nullify; countermand: to override the board’s veto. to take precedence over; preempt or supersede: to override any other considerations. to extend beyond or spread over; overlap.
Can we override method in same class?
No , You can override a method in subclass only. In your case you are overriding Object’s toString() method not Test class method. In one class we can not have method with same signature. this is because there is no need to have override method in same class.
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.
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’.
How do I override toString method?
Overriding toString() in Java The default toString() method in Object prints “class name @ hash code”. We can override toString() method in our class to print proper output. For example, in the following code toString() is overridden to print “Real + i Imag” form.
What is not type of inheritance?
Explanation: Multiple inheritance in java is implemented using interfaces. Multiple interfaces can be implemented by a class. … Explanation: All classes in java are inherited from Object class. Interfaces are not inherited from Object Class.
What is the use of @override?
@Override @Override annotation informs the compiler that the element is meant to override an element declared in a superclass. Overriding methods will be discussed in Interfaces and Inheritance. While it is not required to use this annotation when overriding a method, it helps to prevent errors.

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.
How do you override a method?
If subclass (child class) has the same method as declared in the parent class, it is known as method overriding in Java. In other words, If a subclass provides the specific implementation of the method that has been declared by one of its parent class, it is known as method overriding.
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).
What is overriding and overloading?
Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding occurs when two methods have the same method name and parameters. One of the methods is in the parent class, and the other is in the child class.
Can we call method from constructor?
Calling a method using this keyword from a constructor Yes, as mentioned we can call all the members of a class (methods, variables, and constructors) from instance methods or, constructors.
What is the difference between inheritance and overriding methods?
Inheritance enable us to define a class that takes all the functionality from parent class and allows us to add more. Method overriding occurs simply defining in the child class a method with the same name of a method in the parent class .
Can we override final method?
You can declare some or all of a class’s methods final. You use the final keyword in a method declaration to indicate that the method cannot be overridden by subclasses.
