in java, you cannot explicitly declare a method as constant like in c++. however, you can achieve similar behavior by using the final keyword for method parameters or local variables to ensure they are not modified within the method. what is the purpose of a declaration file in javascript?

declared in outer class. Since a method can be declared as static or non-static, similarly nested classes can be static and non-static. Static class is like a static method, it can only access outer class members through objects. Non-static class can access any member of the outer class....
public static void main(String args[]){ Square r=new Square(); r.draw(); r.sides(); }} Multiple Inheritance in Java We can’t achieve multiple inheritances in Java through the class. It gives a compile-time error. Let me explain to you why! suppose there is a child class C and...
resolved at compile-time based on the class type rather than at runtime based on the object type. Therefore, static methods cannot be overridden or exhibit polymorphic behavior. When you call a static method, it is always the version defined in the class in which it is declared that gets ...
