# Java named lock
### 1 Quick Reference.
The named-lock is a utility for acquiring named locks.
#### 1.1 Named factory.
Main class
```java
public class Test {
public static void main(String[] args) throws InterruptedException{
NamedLockFactory lockFactory = new NamedLockFactory();
System.out.println("start test");
Lock lock = lockFactory.getLock("lock_name");
lock.lock();
try{
Task task = new Task(lockFactory);
task.start();
Thread.sleep(1000);
System.out.println("1");
}
finally{
lock.unlock();
}
Thread.sleep(1000);
System.out.println("end test");
}
}
```
Task class
```java
public class Task extends Thread{
private NamedLockFactory lockFactory;
public Task(NamedLockFactory lockFactory){
this.lockFactory = lockFactory;
}
public void run(){
Lock lock = lockFactory.getLock("lock_name");
lock.lock();
try{
System.out.println("2");
}
finally{
lock.unlock();
}
}
}
```
output:
```
start test
1
2
end test
```
#### 1.2 Named lock.
```java
NamedLock namedLock = new NamedLock()
Serializable refLock = namedLock.lock("lock_name");
try{
// manipulate protected state
}
finally{
namedLock.unlock(refLock, "lock_name");
}
```
