Java deadlock生成的示例分析

Java deadlock生成的示例分析，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。

Java deadlock生成需要我们注意的关键点有很多，其实有不少的问题都能在源代码中寻找到不少的答案。下面我们就看看如何才能更好的做出Java deadlock生成。

public class Deadlock extends Object ...{  private String objID;  public Deadlock(String id) ...{  objID = id;  }  public synchronized void checkOther(Deadlock other) ...{  print("entering checkOther()");  // simulate some lengthy process  try ...{  Thread.sleep(2000);  } catch (InterruptedException x) ...{  }  print("in checkOther() - about to " + "invoke 'other.action()'");  other.action();  print("leaving checkOther()");  }  public synchronized void action() ...{  print("entering action()");  // simulate some work here  try ...{  Thread.sleep(500);  } catch (InterruptedException x) ...{  }  print("leaving action()");  }  public void print(String msg) ...{  threadPrint("objID=" + objID + " - " + msg);  }  public static void threadPrint(String msg) ...{  String threadName = Thread.currentThread().getName();  System.out.println(threadName + ": " + msg);  }  public static void main(String[] args) ...{  final Deadlock obj1 = new Deadlock("obj1");  final Deadlock obj2 = new Deadlock("obj2");  Runnable runA = new Runnable() ...{  public void run() ...{  obj1.checkOther(obj2);  }  };  Thread threadA = new Thread(runA, "threadA");  threadA.start();  try ...{  Thread.sleep(200);  } catch (InterruptedException x) ...{  }  Runnable runB = new Runnable() ...{  public void run() ...{  obj2.checkOther(obj1);  }  };  Thread threadB = new Thread(runB, "threadB");  threadB.start();  try ...{  Thread.sleep(5000);  } catch (InterruptedException x) ...{  }  threadPrint("finished sleeping");  threadPrint("about to interrupt() threadA");  threadA.interrupt();  try ...{  Thread.sleep(1000);  } catch (InterruptedException x) ...{  }  threadPrint("about to interrupt() threadB");  threadB.interrupt();  try ...{  Thread.sleep(1000);  } catch (InterruptedException x) ...{  }  threadPrint("did that break the deadlock?");  }  }

以上就是对Java deadlock生成的详细介绍，希望大家能有所领悟。
