What is Java?
Java is an object-oriented programming language introduced with the feature of "write code once, and run the program anywhere." The applications written in Java are compiled to bytecode that runs on Java Virtual Machine. As a result, the machine installed with Java Virtual Machine can run the Java code. The syntax of Java is similar to the programming language of C++ and C.
Compared to other languages, Java is secure. It does not allow unauthorized access to functions and data, as it has built-in variables and private methods. Java is also a multithreaded language, as it can run multiple tasks simultaneously. It is mainly designed to build object-oriented applications. Java is network-centric. Therefore, it facilitates distributed computing.
Structure of Java
public static void main(String args)
System.out.println("Structure of Java");
The above code demonstrates the structure of the Java program. The variables and methods are enclosed in the black of the class. The statement System.out.println is an output statement.
Advantages of Java
The advantages of Java object-oriented programming language are as follows.
The application designed in Java can run on the operating system or device it supports cross-platform. Java has many frameworks, tools, and libraries to develop any application. Java programming language is reliable, and the errors in the program are checked in the early stage. The compiler can also detect an error that other programming languages cannot detect. Java does support complex features such as multiple inheritances, pointers, and operator overloading.
Disadvantages of Java
The disadvantages of Java object-oriented programming language are as follows. Although Java programming languages have many features, compared to other languages, Java lacks performance. It consumes more memory and runs more slowly than C++ and C.
Application of Java
Java language can be used to develop enterprise software, android apps, big data analytics application, and application related to scientific computing, to develop hardware devices of java programs, and also to develop server-side technologies.

What is C#?
C# programming language is a multi-paradigm. The syntax of C# is expensive. The syntax is similar to other languages like Java, C++, and C. C# language has rectified many complex problems of C++. It also includes many additional features: direct memory access, lambda expression, enumerations, and null value types.
Features of C#
The language C# is based on the current trend and is simple as it has a structured approach with a rich set of data types and library functions. The type-safe code of C# can alone access the location of the memory. Using C#, the developer can develop more scalable applications using predominant software development methods. The time taken for execution and compilation of C# is faster.
Structure of C#
The above code prints the statement C# in the output screen. The system namespace is used in the program—the statement Console.Writeline prints the message on the screen. C# is case-sensitive; hence, all the expressions and statements need to be terminated with the semicolon.
Advantages of C#
The main advantage of C# is it supports the concept of polymorphism, encapsulation, and inheritance. The XML documentation inline comments are supported. The application developed by C# will run if the machine has a .NET framework. It provides support for the distributed system. It is a purely object-oriented language.
Advantages of C#
The disadvantages of C# are as follows:
· C# does not provide interface support directly connecting with firmware and hardware.
· C# language has its byte come and the compiler integrated into the .NET framework, and it does not support single inheritance.
