Question:
Is it necessary to check return value after a “new” statement?Does it return null when it cannot allocate any more memory?

Answer:
You do not have to check the return value of the new operator.Unlike C, where malloc() will return NULL if it fails, the Javanew operator will throw an OutOfMemoryError. OutOfMemoryError is aRuntimeException so you are not forced to catch it.

However, ifyour program needs to be able to recover from running out of memory,you should place a try block at a strategic point where recovery canbe performed.
