Java语言的关键字,当它用来修饰一个方法或者一个代码块的时候,能够保证在同一时刻最多只有一个线程执行该段代码. 1.方法声明时使用,放在范围操作符(public等)之后,返回类型声明(void等)之前.这时,线程获得的是成员锁,即一次只能有一个线程进入该方法,其他线程要想在此时调用该方法,只能排队等候,当前线程(就是在synchronized方法内部的线程)执行完该方法后,别的线程才能进入.例如: public synchronized void synMethod() { //方法体} 2.

1.方法声明时使用,放在范围操作符(public等)之后,返回类型声明(void等)之前.即一次只能有一个线程进入该方法,其他线程要想在此时调用该方法,只能排队等候,当前线程(就是在synchronized方法内部的线程)执行完该方法后,别的线程才能进入. 例如: public synchronized void synMethod() { //方法体 } 2.对某一代码块使用,synchronized后跟括号,括号里是变量,这样,一次只有一个线程进入该代码块.例如: public int sy

android开发之synchronized的用法 在android开发中synchronized主要有四种用法.第一是在方法声明时使用:第二是在对某一代码块时使用:第三是对某一对象使用:第四是对某一类使用.具体的实现代码如下: 1.方法声明时使用 放在范围操作符(public等)之后,返回类型声明(void等)之前.这时,线程获得的是成员锁,即一次只能有一个线程进入该方法,其他线程要想在此时调用该方法,只能排队等候,当前线程(就是在synchronized方法内部的线程)执行完该方法后,别的线
