Exception in thread “Thread-1” java.lang.
Exceptions in thread Thread-1 java.lang.
Exception in thread Thread-1 java.lang.NullPointerException in thread Thread-1 java.lang.
The thread started by the exception in question is the first thread that gets created in the run method of the class. In this case, the first thread that gets created is Thread-1.
There are some exceptions that are specific to the Java™ programming language that we have to be aware of. This one is actually one of those exceptions. It is the only exception that is specific to Java™ and not a part of the Java™ Runtime.
The first thread that gets created in the run method of the class (the one where the exception is thrown) is the thread that creates the run method. The run method is only called once, and every time it is called, the thread that was the thread that runs it will get the exception thrown. The thread that causes the exception is the one that gets the run method called. The thread that gets the called method is the one that is called to execute the run method.
The most common cause of this exception is that a value of the specified type is null. That is typically because an object was passed into the run method that was not of the specified type. It can also be caused by not calling the run method before the first thread executes that method. The exception is thrown if the specified Thread has not been executed yet, but is waiting to execute the run method.
