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 it extends class A & class B. In this scenario, suppose A & B classes have the method with ...
A program that contains multiple flows of control is known as a multithreaded program. The ability of language to support multithread is referred to as concurrency. Since threads in Java are subprograms of the main application and share the same memory space, they are also known as lightweight...
Inheritance in javais a mechanism in which one object acquires all the properties and behaviors of parent object. Types of Inheritance 1- single 2- multilevel 3- hierarchical Note: Java does not support multiple inheritance // Example of Inheritance package programs; class emp{ int sal=1000; }...

Java doesn’t support multiple-class inheritance. Subclasses of an abstract class in Java must implement all the abstract methods unless the subclass is also abstract. In interfaces, all methods are inherently abstract, except for static or default methods, which were introduced in Java 8. Java ...
In more concrete terms, an object is able to pass on its state and behaviors to its children. For inheritance to work, the objects need to have characteristics in common with each other. InJava, classes can be taken from other classes, which can be taken from others, and so on. This ...

While polymorphism is commonly associated with inheritance, it is not solely dependent on it. Polymorphism can also be achieved through interfaces or abstract classes, where multiple unrelated classes implement a common interface or extend the same abstract class. This allows objects of different types...
when you delete an instance, the system frees up the memory that was allocated to it. if you're using a language with garbage collection, like python or java, this process is usually automatic. however, in languages without garbage collection, you have to manually deallocate memory. can an ...
