Simple Thread Blocking Method
When this method is called, it tells the thread dispatching mechanism that I can execute without being busy, although this scenario may not necessarily execute.
Local method public static native void yield(); join()When this method is called, threads A call B.join() on thread B, and threads A are suspended until B.isAlive() returns false.We can also call the interrupt method on our own and the terminal join () method
public final void join() throws InterruptedException { this.join(0L); } //Default incoming parameter 0L public final synchronized void join(long var1) throws InterruptedException { long var3 = System.currentTimeMillis();//Get Current Time Assumption 1513000171971 long var5 = 0L; if (var1 < 0L) { throw new IllegalArgumentException("timeout value is negative"); } else { if (var1 == 0L) { //The default is 0, so enter this method while(this.isAlive()) { //If this thread has always been alive, it will wait this.wait(0L); } } else {//If there is a value, it represents a timeout parameter, and if it exceeds that time, it returns itself if it has not finished while(this.isAlive()) { //Let's assume var1=1000 long var7 = var1 - var5; //The first var5 is 0, var1==var7==1000 if (var7 <= 0L) {//1000<=0L-—>false break;//Until run to break } this.wait(var7);//Waiting for 1000L //var5 = 1513000191262-1513000171971=19291 var5 = System.currentTimeMillis() - var3; } } } }Sleep()
