在现代的程序开发中，多线程是必不可少的，熟练使用多线程能够极大的提高项目并发，本篇文章我们就来看看一些多线程编程案例。
例1：
package com.kelin1314;
public class TestObject
{
private String name;
private boolean flag = true;
public TestObject(String name)
{
this.name = name;
}
public synchronized String getName()
{
try
{
System.out.println("begin get");
while (!flag)
{
wait();
}
flag = true ? (flag = false) : (flag = true);
System.out.println("over get");
notify();
}
catch (Exception e)
{
e.printStackTrace();
}
return name;
}
// public synchronized static void setName(String name) {
public synchronized void setName(String name)
{
try
{
System.out.println("begin set");
while (flag)
{
wait();
}
flag = true ? (flag = false) : (flag = true);
System.out.println("over set");
notify();
}
catch (Exception e)
{
e.printStackTrace();
}
}
}

package com.kelin1314;
/**
* This thread is used to test the variable scope of key word "synchronized".

* @author Administrator

*/
public class TestThreadOne extends Thread
{
private TestObject object;
public TestThreadOne(TestObject object)
{
this.object = object;
}
@Override
public void run()
{
while (true)
{
object.getName();
}
}
}
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
package com.kelin1314;
public class TestThreadTwo extends Thread
{
private TestObject object;
public TestThreadTwo(TestObject object)
{
this.object = object;
}
@Override
public void run()
{
while (true)
{
object.setName("two");
}
}
}
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -
package com.kelin1314;
public class Main
{
/**
* @param args
*/
public static void main(String[] args)
{
TestObject object = new TestObject("object");
TestThreadOne testThreadOne = new TestThreadOne(object);
TestThreadTwo testThreadTwo = new TestThreadTwo(object);
testThreadOne.start();
testThreadTwo.start();
}
}例2：
from threading
import Thread
msg_l = []
format_l = []
def talk():
while True:
msg = input('>>: ')
.strip()
if not msg: continue
msg_l.append(msg)
def format_msg():
while True:
if msg_l:
res = msg_l.pop()
format_l.append(res.upper())
def save():
while True:
if format_l:
with open('db.txt', 'a', encoding = 'utf-8') as f:
res = format_l.pop()
f.write('%s\n' % res)
if __name__ == '__main__':
t1 = Thread(target = talk)
t2 = Thread(target = format_msg)
t3 = Thread(target = save)
t1.start()
t2.start()
t3.start()以上就是本篇文章的所有内容，更多java经典实例内容可以关注奇Q工具网了解详情。
