Why Java does not support multiple inheritances? tccicomputercoaching.com

The main reason is that when we declared a same method in different class and at the time of calling the method present at these classes the compiler gets confused which class method would be called so this may result the ambiguity occur in program and compiler throw a compile-time error. This is the main reason that java doesn’t support multiple inheritance.

What are the advantages of Inheritance in C++? tccicomputercoaching.com

Definition:

Inheritance is mechanism to build a new class from existing one.

Advantage of Inheritance:

One of the key benefits of inheritance is to minimize the amount of duplicate code in an application by sharing common code amongst several subclasses, where equivalent code exists in two related classes. This also tends to result in a better organization of code and smaller, simpler compilation units.

advantage of inheritance in cplus

Inheritance can also make application code more flexible to change because classes that inherit from a common super class can be used interchangeably.

Reusability-> facility to use public methods of base class without rewriting the same.

Extensibility-> extending the base class logic as per business logic of the derived class

Data hiding-> base class can decide to keep some data private so that it cannot be altered by the derived class

Overriding-> With inheritance, we will be able to override the methods of the base class so that meaningful implementation of the base class method can be designed in the derived class.

TCCI is located in Bopal and Satellite in Ahmedabad. We teach all programming Languages to school- Engineering- BCA – MCA students, and Employee of Industry.

What is JVM, JRE and JDK? tccicomputercoaching.com

How Java Compiler Works?

Java has compiler name as javac which convert source code to intermediate code which is known as java bytecode. This java bytecode is not dependent on any platform that is if you compile your source code in windows platform by using javac compiler so you can run this code in any other platforms like Linux, Mac.

Java-JDK-JRE-and-JVM

What is JVM?

JVM (Java Virtual Machine) is an abstract machine. It is called virtual machine because it doesn’t physically exist. It is a specification that provides runtime environment in which java bytecode can be executed. It can also run those programs which are written in other languages and compiled to Java bytecode.

JVMs are available for many hardware and software platforms. JVM, JRE and JDK are platform dependent because configuration of each OS is different from each other. But, Java is platform independent. There are three notions of the JVM: specification, implementation, and instance.

The JVM performs following main tasks:

  • Loads code
  • Verifies code
  • Executes code
  • Provides runtime environment

What is JRE?

JRE is an acronym for Java Runtime Environment. It is also written as Java RTE. The Java Runtime Environment is a set of software tools which are used for developing java applications. It is used to provide runtime environment. It is the implementation of JVM. It physically exists. It contains set of libraries + other files that JVM uses at runtime.

Implementation of JVMs is also actively released by other companies besides Sun Micro Systems.

What is JDK?

JDK is an acronym for Java Development Kit. The Java Development Kit (JDK) is a software development environment which is used to develop java applications and applets. It physically exists. It contains JRE + development tools.

JDK is an implementation of any one of the below given Java Platforms released by Oracle corporation:

  • Standard Edition Java Platform
  • Enterprise Edition Java Platform
  • Micro Edition Java Platform

The JDK contains a private Java Virtual Machine (JVM) and a few other resources such as an interpreter/loader (Java), a compiler (javac), an archiver (jar), a documentation generator (Javadoc) etc. to complete the development of a Java Application.

What is User Defined Function? tccicomputercoaching.com

function is a set of instructions that performs a specific task.

In Programming there are two types of functions:

1. Built in Function

2. User defined function

Built in Function is already written, tested and stored in source file. User just uses them in programme. So, related library file have to include in programme.

user defined function

User Defined Function is developed by User at a time and no need to include source file in programme.

There are 3 sections of User Defined Function:

1. Function Declaration

2. Function Definition

3. Function Call

To learn more in detail about function in Programming Language.

Join TCCI in Bopal and Satellite in Ahmedabad. We conduct Online coaching also.
