package com.tutorialspoint; import java.lang.*; public class ThreadLocalDemo { public static void main(String[] args) { ThreadLocal<Integer> tlocal = new ThreadLocal<Integer>(); /* sets the current thread's copy of this thread-local variable to the specified value. */ tlocal.set(50); // returns the current thread's value of this thread-local System.out.println("value = " + tlocal.get()); // removes the current thread's value tlocal.remove(); // returns the current thread's value of this thread-local System.out.println("value = " + tlocal.get()); } }
Let us compile and run the above program, this will produce the following result −
value = 50 value = null
