java.lang.Process.waitFor()方法将导致当前的线程等待，如果必要的话，直到由该Process对象表示的进程已经终止。此方法将立即返回，如果子进程已经终止。如果子进程尚未终止，则调用线程将被阻塞，直到子进程退出。public class ProcessDemo {public static void main(String[] args) {try {// create a new processSystem.out.println("Creating Process...");Process p = Runtime.getRuntime().exec("notepad.exe");// cause this process to stop until process p is terminatedp.waitFor();// when you manually close notepad.exe program will continue hereSystem.out.println("Waiting over.");} catch (Exception ex) {ex.printStackTrace();}}
