List at least three reasons why Java is used by companies such as Sun and IBM to develop their major applications. Why might a programmer choose another language?
What will be an ideal response?
Four possible reasons to use Java are:
1. It is a modern object-oriented programming language that uses the best features of languages such as C++ and Smalltalk.
2. Java is secure (tamper- and virus-free), robust (programs do not overwrite memory), and portable (programs can be run on different computer types).
3. Java uses advanced programming concepts, such as threads.
4. Java resembles C++, making it easy for C++ programmers to learn Java and vice versa.
Why a programmer might choose another lanugage:
Java runs more slowly than other modern programming languages because it must be interpreted using a JVM.
