** Week1 Discussion [#ga621d0d]

- Question

Languages can be fully compiled, fully interpreted or partially compiled and then interpreted. Choose a language from the list of the top 20 currently most popular languages at http://www.tiobe.com/tpci.htm. Choose one that has not already been chosen by one of your classmates. Discuss which of the three translations mechanisms is used with that language. Offer some rationale for why that mechanism was chosen.

- Answer

I chose Java. When you run a Java program, your source code is partially compiled by the Java compiler and then interpreted by Java Virtual Machine (JVM). The JVM allows you to develop programs without dependence on operating systems.

A major function of JVM is supporting garbage collection, which automatically frees dynamically allocated memory on the heap. When you create a instance of an object by using new operator, memory is automatically allocated on the heap. Therefore, you don't have to care about memory allocation and deallocation unlike C.
