An example of understanding wait () and Policy () The following is a post I saw on the csdn forum, which involves the understanding of synchronization, wait (), notify (), and other concepts, I tried to analyze the wait () and Policy () methods based on some original replies and related concepts in think in Java. Thank you for your advice.The problem is as follows:// Analyze this program and explain it, foc
