Causes the current thread to wait, if necessary, until the process represented by this Process object has terminated.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    String fileName = "c:\\temp\\test.bmp";
    String[] commands = { "cmd.exe", "/c", "start", "\"DummyTitle\"", "\"" + fileName + "\"" };
    Process p = Runtime.getRuntime().exec(commands);
    p.waitFor();
    System.out.println("Done.");
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    Process process = Runtime.getRuntime().exec("ls -al");
    process.waitFor();

    int exitValue = process.exitValue();
    System.out.println("exitValue = " + exitValue);
    BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()));
    String line = "";
    while ((line = reader.readLine()) != null) {
        System.out.println(line);
    }/*from  w ww  .  java  2 s  . c  o m*/
}

From source file:ProcessBuilderDemo.java

    environ.put("PATH", "/windows;/windows/system32;/winnt");
    builder.directory(new File(System.getProperty("user.home")));

    final Process godot = builder.start();

    try {
        System.out.println("Exit status = " + p.waitFor());
    } catch (InterruptedException e) {
    }
}

From source file:Main.java

    try {/* ww  w.  j ava2  s.c om*/
        // create a new process
        Process p = Runtime.getRuntime().exec("notepad.exe");

        // cause this process to stop until process p is terminated
        p.waitFor();

        // when you manually close notepad.exe this program will continue
        System.out.println("Waiting over.");
