No, after the start method is called, the thread only becomes the ready state, not the running state - then the JVM arranges when the thread runs (that is, executes the run method of Thread)
Since thread concurrency is used, the key issue to consider is not the order of execution. If you have to do it on a first-come, first-served basis, then use the join method
