Difference Between Java and .NET

  • Last Updated : 28 Jan, 2021

Java is an object-oriented and platform-independent high-level programming language which is developed by Sun Microsystem. It is considered as the foundation for virtually every type of networked application. With the help of the Java programming language, we can develop and deliver global standard embedded applications, mobile applications, enterprise applications, games, and web-based content, etc.

Advantages of Java:

  • Simple programming language
  • Object-Oriented Programming
  • Platform-Independent
  • Distributed computing
  • Secure language
  • Multi-threaded
  • Cheap and economical to maintain

Disadvantages of Java:

  • Single-Paradigm Language
  • Memory consuming and slower than natively compiled languages
  • Slow and has a poor performance
  • No Unsigned Types
  • Does not provide so attractive look and feels of the GUI
  • Less machine interactive

.NET is a cross-platform, open-source software framework used for developing software applications that are developed by Microsoft. It supports the building and running of next-generation applications and web services. With the help of .NET, we can create reusable modules, as a result, it makes the application code error-free and improves productivity.

Advantages of .NET :

  • Multi-tiered software architecture
  • Cross-platform design
  • Object-Oriented Programming
  • Great Caching System
  • Universal .NET Standard
  • Flexible Deployment and Easy Maintenance
  • Automatic monitoring in ASP.NET

Disadvantages of .NET:

  • Limited Object-Relational Support
  • Memory Leaks
  • Slower than Native Code
  • Vendor lock-in
  • Migrating applications is expensive
  • Stability Issues for New Releases

Difference between Java and .NET :



Java is an object-oriented and platform-independent high-level programming language..NET is a cross-platform, open-source software framework used for developing a software applications.
It is developed by Sun Microsystem.It is developed by Microsoft.
Java requires JVM (Java Virtual Machine) for execution means during runtime..NET requires CLR (Common Language Runtime) for execution means during runtime.
It supports multiple Operating Systems a third-party system.It only supports Windows Operating System.
Java provides a less efficient manner of garbage collection as compared to .NET..NET provides a more efficient manner of garbage collection as compared to Java.
In Java JDBC (Java Data Base Connectivity) is used for the database connection.In .NET ADO (ActiveX Data Objects (ADO) is used for database connection.
For Java multiple third-party IDEs (Integrated Development Environment) are available.It has a standard IDE (Integrated Development Environment) i.e. Microsoft Visual Studio.
It supports connected architecture.It supports disconnected architecture.
It is a step behind .NET in case of providing security.It is a step ahead in case of providing security.
It provides a little harder exception handling concept than .NET.It provides an easier exception handling concept than Java.
