Multithreading Foundation (XI) -- prevent CPU from occupying 100%

sleep Realization

Without using cpu To calculate , Don't let while(true) Idling waste cpu, You can use yield or sleep Come out cpu The right to use is given to other programs

while(true) {
    
	try {
    
		Thread.sleep(10);
	} catch (InterruptedException e) {
    
		e.printStackTrace();
	}
}

• It can be used wait Or conditional variables to achieve similar effects
• The difference is , The latter two need to be locked , And the corresponding wake-up operation is required , It is generally applicable to the scene to be synchronized
• sleep It is suitable for scenarios without lock synchronization
