Answer 3

• It is Simple & Portable: Memory Management using Pointers is not allowed.

• It is Secured & Dynamic: Designed to execute code from remote sources securely.
• It contains language facilities and libraries for Networking.
• High Performance: With the use of JIT (Just-In-Time) compilers, Java achieves high performance through the use of byte code that can be easily translated into native machine code.
• It is Robust: Java has its own strong memory management system. This helps to eliminate errors as it checks the code during compile and runtime.

-Java is Multithreaded: It supports multiple executions of threads (i.e., lightweight processes), including a set of synchronization primitives.
