Answer 1

The wait is the method owned by Object, to use the method, you must get the lock of the object, change your code to,

try
{
    Runtime runtime = Runtime.getRuntime();
    String cmd = new String(C:\\abc.bat);
    process = runtime.exec("\"" + cmd + "\"");
    synchronized (process){
       try{
          process.wait();
       } catch (InterruptedException e) {
          e.printStackTrace();
       }
    }
}
catch (Exception e)
{
   e.printStackTrace();
}
