What is the difference between paint and repaint methods of java?
The paint method is where actual painting occurs. If you want to change the way a Component is drawn, you should override this method.

The Java API warns not to ever directly call the paint method, mostly for efficiency reasons.
How do you call a method from inside the main method?
I assume the question is about Java. How you call a method from inside the main method depends on whether this is an instance method or a static method. To call an instance method, you need to have a valid instance. Say foo is an instance of class Foo, which was created inside the main method. Then to call the instance method implode() use foo.implode() To call the static method bar() of class Foo, use Foo.bar().
What is dynamic method dispatch in java?
Dynamic Method Dispatch in Java is when a method call is resolved at runtime based on the actual object the reference points to. For example, if a parent class has a method and a child class overrides it, a parent reference pointing to a child object will execute the child’s version of the method. This allows Java to decide which method to run during execution, enabling runtime polymorphism. To dive deeper into this topic, visit the Uncodemy blog for detailed insights.
