Java Unique Interview Questions in Tamil | Part 1 | JAVA | DinaTechy

In this video,

1. Can we override static method in java?
No, we cannot override static method in Java as it is bound to the class and not to the instance of the class. Subclasses can define a static method with the same signature as the parent class, but this is not considered an override.

2. Can you overload main method in java?
Yes, we can overload the main method in Java. This means we can define multiple main methods in a class with different parameter types or numbers, but only the main method with the signature "public static void main(String[] args)" will be executed when the program is run.

3. Can we override private methods in java?
No, we cannot override private methods in Java as they are not accessible to subclasses. Private methods are only accessible within the class they are defined in and cannot be accessed or overridden by other classes, including subclasses.


4. What is the base class for all the classes?
The base class for all the classes in Java is the Object class. Every class in Java is a subclass of the Object class, either directly or indirectly. This means that all classes inherit certain methods and properties from the Object class, such as the toString() method and the equals() method.

5. Can you list down some of important method from object class?
Some of the important methods from the Object class in Java include:

toString(): returns a string representation of the object
equals(Object obj): compares the object with another object for equality
hashCode(): returns a hash code value for the object
getClass(): returns the runtime class of the object
wait(): causes the current thread to wait until another thread notifies it
notify(): wakes up a single thread that is waiting on the object's monitor
notifyAll(): wakes up all threads that are waiting on the object's monitor
