Attributes

Remarks

Runs the garbage collector.

Calling the gc method suggests that the Java Virtual Machine expend effort toward recycling unused objects in order to make the memory they currently occupy available for quick reuse. When control returns from the method call, the Java Virtual Machine has made a best effort to reclaim space from all discarded objects.

The call System.gc() is effectively equivalent to the call: <blockquote>

Runtime.getRuntime().gc()

</blockquote> At API level 34 and lower, this does nothing unless it is preceded or followed by a runFinalization call. Runtime.getRuntime().gc() always attempts to reclaim space.

Calling this indiscriminately is likely to severely degrade performance. Intended primarily for testing.
