## Java字符串常量池 ##

            System.out.println(str1==str1.intern());//true
            System.out.println();
    
            /* sum.misc.Version类会在JDK类库的初始化中被加载并初始化,而在初始化时它需要对静态常量字 段根据指定的常量值(ConstantValue)做默认初始化,此时sum.misc.Version.launcher静态常 量字段所引用的"java"字符串字面量就被intern到HotSpot VM的字符串常量池 - StringTable 里了 str2对象是堆中的 str.intern()是返回的是JDK出娘胎自带的,在加载sum.misc.version这个类的时候进入常量池 */
            String str2=new StringBuilder("ja").append("va").toString();
            System.out.println(str2);
            System.out.println(str2.intern());
            System.out.println(str2==str2.intern());//false ，只有jdk自带的字符串如"java"字符串是false,其他字符串都是true
    
        }
    }

显示(收动挡)是指：需要自己显示的lock和unLock

### sychronized ###

隐式锁:(即synchronized关键字使用的锁)默认是可重入锁(同步块、同步方法)  
原理如下：

*  每个锁对象拥有一个锁计数器和一个指向持有该锁的线程的指针
 *  当执行monitorenter时,如果目标锁对象的计数器为零,那么说明它没有被其他线程持有,Java虚拟机会将该锁对象的持有线程设置为当前线程,并且将其计数器加1,否则需要等待,直至持有线程释放该锁
 *  当执行monitorexit时,Java虚拟机则锁对象的计数器减1。计数器为零代表锁已经被释放

//1.同步代码块

//1.同步代码块
    public class SychronizedDemo { 
        Object object=new Object();
    
        public void sychronizedMethod(){ 
           new Thread(()->{ 
               synchronized (object){ 
                   System.out.println(Thread.currentThread().getName()+"\t"+"外层....");
                   synchronized (object){ 
                       System.out.println(Thread.currentThread().getName()+"\t"+"中层....");
                       synchronized (object){ 
                           System.out.println(Thread.currentThread().getName()+"\t"+"内层....");
                       }
                   }
               }
           },"A").start();
        }
        public static void main(String[] args) { 
            new SychronizedDemo().sychronizedMethod();
            /* 输出结果： A 外层.... A 中层.... A 内层.... * */
        }
    }

//2.同步方法

public class ReEnterLockDemo { 
        public synchronized void m1() { 
            System.out.println("=====外");
            m2();
        }
        public synchronized void m2() { 
            System.out.println("=====中");
            m3();
        }
        public synchronized void m3() { 
            System.out.println("=====内");
        }
    
        public static void main(String[] args) { 
            new ReEnterLockDemo().m1();
        }
    
    }

输出结果

=====外
    =====中
    =====内

### ReentrantLock ###

显示锁:(即lock)也有ReentrantLock这样的可重入锁  
(注意：有多少个lock,就有多少个unlock,他们是配对使用的；如果多一个或者少一个会使得其他线程处于等待状态)

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lhbmdzaGVuZ3dlaTIzMDYxMg_size_16_color_FFFFFF_t_70_pic_center 12]

class Phone2{ 
       static ReentrantLock reentrantLock=new ReentrantLock();
    
        public static void sendSms(){ 
            reentrantLock.lock();
            /* //reentrantLock.lock(); 注意有多少个lock,就有多少个unlock,他们是配对使用的 如果多了一个lock(),那么会出现线程B一直处于等待状态 * */
            reentrantLock.lock();
            try { 
                System.out.println(Thread.currentThread().getName()+"\t"+"sendSms");
                sendEmails();
            }catch (Exception e){ 
                e.printStackTrace();
            }finally { 
                reentrantLock.unlock();
            }
        }
    
        private static void sendEmails() { 
            reentrantLock.lock();
            try { 
                System.out.println(Thread.currentThread().getName()+"\t"+"sendEmails...");
            }catch (Exception e){ 
                e.printStackTrace();
            }finally { 
                reentrantLock.unlock();
            }
        }
    }
    public class ReentrantLockDemo { 
        public static void main(String[] args) { 
            Phone2 phone2=new Phone2();
            new Thread(()->{ phone2.sendSms();},"A").start();
            new Thread(()->{ phone2.sendSms();},"B").start();
        }
    }

### LockSupport ###

**LockSupport就是对线程唤醒机制(wait/notify)的升级加强版**  
![在这里插入图片描述][20201025151647514.png_pic_center]  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lhbmdzaGVuZ3dlaTIzMDYxMg_size_16_color_FFFFFF_t_70_pic_center 13]  
**3种让线程等待唤醒的方法：**  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lhbmdzaGVuZ3dlaTIzMDYxMg_size_16_color_FFFFFF_t_70_pic_center 14]

#### synchronized -->wait( )和notify( ) ####

Object类中wait( )和notify( )实现线程的等待唤醒  
wait( )：阻塞线程  
notify( )：唤醒线程

**1. wait和notify方法必须要在synchronized 同步块或同步方法里且成对出现使用。**  
**2. 必须先wait后再notify(如果先notify后wait会出现另一个线程一直处于等待状态)**

正常使用  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lhbmdzaGVuZ3dlaTIzMDYxMg_size_16_color_FFFFFF_t_70_pic_center 15]

*  wait和notify方法必须要在synchronized 同步块或同步方法里且成对出现使用。 wait和notify方法两个都去掉同步代码块后看运行效果出现异常情况:

Exception in thread “A” Exception in thread “B”
    java.lang.IllegalMonitorStateException

wait和notify方法不能脱离synchronized 同步块或同步方法使用  
![在这里插入图片描述][20201025153417732.png_pic_center]  
不是synchronized 同步块或同步方法使用  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lhbmdzaGVuZ3dlaTIzMDYxMg_size_16_color_FFFFFF_t_70_pic_center 16]

*  先notify后wai  
    先wait后notify才可以(如果先notify后wait会出现另一个线程一直处于等待状态)

#### ReentrantLock–>await()和signal() ####

Condition接口中的await和signal方法实现线程等待和唤醒  
(出现的问题和object中wait和notify一样)

**1. await()和signal()方法必须要在lock和unLock同步块或同步方法里且成对出现使用。**  
**2. 必须先await后再signal(如果先signal后await会出现另一个线程一直处于等待状态)**

![在这里插入图片描述][20201025154655248.png_pic_center]

public class LockDemo { 
        static Object object=new Object();
        public static void main(String[] args) { 
            Lock lock=new ReentrantLock();
            Condition condition = lock.newCondition();
    
            new Thread(()->{ 
                //如果把下行这句代码打开,先signal后await,会出现A线程一直处于等待状态
                //try { TimeUnit.SECONDS.sleep(3); } catch (InterruptedException e) {e.printStackTrace();}
                lock.lock();
                try { 
                    System.out.println(Thread.currentThread().getName()+"\t"+"coming....");
                    condition.await();
                }catch (Exception e){ 
                    e.printStackTrace();
                }finally { 
                    lock.unlock();
                }
                System.out.println(Thread.currentThread().getName()+"\t"+"END....");
            },"A").start();
    
            new Thread(()->{ 
                lock.lock();
                try { 
                    System.out.println(Thread.currentThread().getName()+"\t"+"唤醒A线程****");
                    condition.signal();
                }catch (Exception e){ 
                    e.printStackTrace();
                }finally { 
                    lock.unlock();
                }
            },"B").start();
        }
    }

#### LockSupport–>park()和unpark() ####

1.  不用必须写在锁代码块中
2.  先unpark()，唤醒再park()阻塞，阻塞无效
