States of thread
A thread can be in one of the following states - ready, waiting for some action, running, and dead. These states are explained below.
Ready State A thread in this state is ready for execution, but is not being currently executed. Once a thread in the ready state gets access to the CPU, it gets converted to running state.
Running State A thread is said to be in running state when it is being executed. This thread has access to CPU.
Dead State A thread reaches "dead" state when the run method has finished execution. This thread cannot be executed now.
Waiting State In this state the thread is waiting for some action to happen. Once that action happens, the thread gets into the ready state. A waiting thread can be in one of the following states - sleeping, suspended, blocked, waiting for monitor.
0 A dead Thread cannot be restarted.
0 If you call its start() method after its death, IllegalThreadStateException will be thrown.
0 Even the Thread is dead, but you still can call its other method. Why? Simple, the Thread is just another Java Object. For example, if you call its run() method again, it will be just a sequential procedure call, no concurrent execution at all.
thread.join(): The effect of calling jobT.join() statement is that current thread waits for jobT to complete.
thread.isAlive(): The isAlive method returns true if the thread has been started and not stopped. If the isAlive method returns false, you know that the thread either is a New Thread or is Dead.

Oi, achei seu blog pelo google está bem interessante gostei desse post. Gostaria de falar sobre o CresceNet. O CresceNet é um provedor de internet discada que remunera seus usuários pelo tempo conectado. Exatamente isso que você leu, estão pagando para você conectar. O provedor paga 20 centavos por hora de conexão discada com ligação local para mais de 2100 cidades do Brasil. O CresceNet tem um acelerador de conexão, que deixa sua conexão até 10 vezes mais rápida. Quem utiliza banda larga pode lucrar também, basta se cadastrar no CresceNet e quando for dormir conectar por discada, é possível pagar a ADSL só com o dinheiro da discada. Nos horários de minuto único o gasto com telefone é mínimo e a remuneração do CresceNet generosa. Se você quiser linkar o Cresce.Net(www.provedorcrescenet.com) no seu blog eu ficaria agradecido, até mais e sucesso. If is possible add the CresceNet(www.provedorcrescenet.com) in your blogroll, I thank. Good bye friend.
