		File scriptFile = new File("/home/java2novice/test.sh");
		System.out.println("Current file permissions:");
		System.out.println("Can Execute? "+scriptFile.canExecute());
		System.out.println("Can Read? "+scriptFile.canRead());
		System.out.println("Can Write? "+scriptFile.canWrite());
		scriptFile.setExecutable(true);
		scriptFile.setReadable(true);
		scriptFile.setWritable(true);
		System.out.println("Now file permissions:");
		System.out.println("Can Execute? "+scriptFile.canExecute());
		System.out.println("Can Read? "+scriptFile.canRead());
		System.out.println("Can Write? "+scriptFile.canWrite());

What is race condition?
A race condition is a situation in which two or more threads or processes are reading or writing some shared data, and the final result depends on the timing of how the threads are scheduled. Race conditions can lead to unpredictable results and subtle program bugs. A thread can prevent this from happening by locking an object. When an object is locked by one thread and another thread tries to call a synchronized method on the same object, the second thread will block until the object is unlocked.
