What is a thread-local variable in Java?

A thread-local variable in Java is a variable that is local to each individual thread. This means that each thread has its own separate copy of the variable, and changes made to the variable in one thread do not affect the value of the variable in other threads. Thread-local variables are typically used to store data that is specific to each thread, such as thread-specific configurations or thread-specific state.
