### Uses of ThreadGroup in java.lang

Methods in java.lang that return ThreadGroup
`ThreadGroup` ThreadGroup.`getParent()` Returns the parent of this thread group.
`ThreadGroup` SecurityManager.`getThreadGroup()` Returns the thread group into which to instantiate any new thread being created at the time this is being called.
`ThreadGroup` Thread.`getThreadGroup()` Returns the thread group to which this thread belongs.

Methods in java.lang with parameters of type ThreadGroup
`void` SecurityManager.`checkAccess(ThreadGroup g)` Throws a `SecurityException` if the calling thread is not allowed to modify the thread group argument.
`int` ThreadGroup.`enumerate(ThreadGroup[] list)` Copies into the specified array references to every active subgroup in this thread group and its subgroups.
`int` ThreadGroup.`enumerate(ThreadGroup[] list, boolean recurse)` Copies into the specified array references to every active subgroup in this thread group.
`boolean` ThreadGroup.`parentOf(ThreadGroup g)` Tests if this thread group is either the thread group argument or one of its ancestor thread groups.

Constructors in java.lang with parameters of type ThreadGroup
Constructor and Description
`Thread(ThreadGroup group, Runnable target)` Allocates a new `Thread` object.
`Thread(ThreadGroup group, Runnable target, String name)` Allocates a new `Thread` object so that it has `target` as its run object, has the specified `name` as its name, and belongs to the thread group referred to by `group`.
`Thread(ThreadGroup group, Runnable target, String name, long stackSize)` Allocates a new `Thread` object so that it has `target` as its run object, has the specified `name` as its name, and belongs to the thread group referred to by `group`, and has the specified stack size.

`Thread(ThreadGroup group, Runnable target, String name, long stackSize, boolean inheritThreadLocals)`
Allocates a new `Thread` object so that it has `target` as its run object, has the specified `name` as its name, belongs to the thread group referred to by `group`, has the specified `stackSize`, and inherits initial values for inheritable thread-local variables if `inheritThreadLocals` is `true`.

`Thread(ThreadGroup group, String name)` Allocates a new `Thread` object.
`ThreadGroup(ThreadGroup parent, String name)` Creates a new thread group.
