(throughput) collector? The throughput collector uses a parallel version of the new generation garbage collector, which is used for medium-sized and large-scale data applications. The serial collector is sufficient for most small applications, which require about 100M of memory on modern processors. 41. In Java, when can objects be garbage collected? This object can be recycled when the object becomes inaccessible to applications that currently use t

do not need to use the Futuretask class, it becomes very useful when we intend to rewrite some methods of the future interface and keep the original base implementation.
