runback to summary
public void run()

Overrides java.lang.Thread.run.

Implements java.lang.Runnable.run.

Doc from java.lang.Thread.run.

This method is run by the thread when it executes. Subclasses of Thread may override this method.

This method is not intended to be invoked directly. If this thread is a platform thread created with a Runnable task then invoking this method will invoke the task's run method. If this thread is a virtual thread then invoking this method directly does nothing.

Annotations
@Override
setContextClassLoaderback to summary
public void setContextClassLoader(ClassLoader cl)

Overrides java.lang.Thread.setContextClassLoader.

Doc from java.lang.Thread.setContextClassLoader.

Sets the context ClassLoader for this thread.

The context ClassLoader may be set by the creator of the thread for use by code running in this thread when loading classes and resources.

If a security manager is present, its checkPermission method is invoked with a RuntimePermission("setContextClassLoader") permission to see if setting the context ClassLoader is permitted.

Parameters
cl:ClassLoader

the context ClassLoader for this Thread, or null indicating the system class loader (or, failing that, the bootstrap class loader)

Annotations
@Override
setUncaughtExceptionHandlerback to summary
public void setUncaughtExceptionHandler(Thread.UncaughtExceptionHandler x)

Overrides java.lang.Thread.setUncaughtExceptionHandler.

Doc from java.lang.Thread.setUncaughtExceptionHandler.

Set the handler invoked when this thread abruptly terminates due to an uncaught exception.

A thread can take full control of how it responds to uncaught exceptions by having its uncaught exception handler explicitly set. If no such handler is set then the thread's ThreadGroup object acts as its handler.

Parameters
x:Thread.UncaughtExceptionHandler

the object to use as this thread's uncaught exception handler. If null then this thread has no explicit handler.
