Teachers

Simple

• Java derives its syntax from C and object oriented features from C++.
• If you are good in C and C++ programming then you can learn Java easily. Hence Java is Simple.

Secure

• Java provides its own execution environment and hence do not allow any malicious program to access other parts of computer.
• Java Virtual Machine (JVM) verifies the code before execution (sandbox security).

 Portable

• Java is platform independent i.e. Write Once and Run Anywhere (WORA).
• When java program is compiled a .class file (bytecode) is created. This .class file can run on any platform (linux, windows, mac). You just need JVM of that platform.

Robust

• Automatic Memory Management
• Automatic Exception Handling

Object-Oriented

• Java is object oriented programming language same as C++.
• It means focus on the data and methods that manipulate that data instead of taking care of procedures.

Multithreaded

• Java supports multithreaded programming.
• It allows you to write programs that do many things simultaneously.

Architecture-Neutral

• Java is machine independent.
• It was made with goal “write once; run anywhere, anytime, forever”.

Interpreted

• Java enables the creation of cross-platform program i.e. bytecode.
• This code can be executed on any platform that has JVM.

High Performance

• Java bytecode can be easily executed on any machine for very high performance by using a just-in-time (JIT) compiler.

Dynamic

• Java programs carry with them substantial amounts of run-time type information that is used to verify and resolve accesses to objects at run time.

Distributed

• Java enables the creation of distributed applications which can be accessed on the internet.
