memory leak

A memory leak is when allocated memory that is no longer needed is not deallocated. Eventually, the memory pool is unable to satisfy an allocation request, and the program fails. A memory leak is a programming bug.

When class libraries leak memory, they need to be fixed, just like any other piece of code that has bugs. If they came from a vendor, then that vendor needs to fix them.

That means a memory leak in a program written in Java. A memory leak means that as the program runs, more and more memory is wasted - usually by being assigned and not de-assigned again. In Java this is not as usual as in other languages, since unused memory is normally reclaimed automatically by the garbage collector.

Memory leaks do not occur in Java as the garbage collector clears the memory which has no references.
