IllegalMonitorStateException on wait() call

Question

I am using multi-threading in java for my program. I have run thread successfully but when I am using Thread.wait(), it is throwing java.lang.IllegalMonit

Answer 1

Those who are using Java 7.0 or below version can refer the code which I used here and it works.

public class WaitTest {

    private final Lock lock = new ReentrantLock();
    private final Condition condition = lock.newCondition();

    public void waitHere(long waitTime) {
        System.out.println("wait started...");
        lock.lock();
        try {
            condition.await(waitTime, TimeUnit.SECONDS);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        lock.unlock();
        System.out.println("wait ends here...");
    }

    public static void main(String[] args) {
        //Your Code
        new WaitTest().waitHere(10);
        //Your Code
    }

}
