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...
It is the technique in which a child object carries all the properties of its parent object. This mechanism is achieved by building a child class over an existing class which we technically call as parent class by using extends keyword in Java. In this process, a child class can add new ...
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; }...
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...

Understanding when not to use abstract classes is as crucial as knowing their benefits. Multiple Inheritance: Java doesn’t support multiple inheritance for classes. If a class already extends another class, it cannot extend an abstract class. In such cases, interfaces are more suitable, as ...
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 ...
java, and ruby. a low-level programming language, on the other hand, is a language that is designed to be more closely tied to the computer's hardware. low-level programming languages are used for tasks that require a high degree of control over the computer's hardware. examples of low-...
