两个线程交替打印1到100
1 两个线程交替打印1到100
static volatile int falg = 0;
@Test
public void test001()
Thread threadA = new Thread(new Runnable()
@Override
public void run()
int i = -1;
while(i < 100)
if(KinglexCompanyExecutorApplicationTests.falg == 0)
i = i + 2;
System.out.println(i);
KinglexCompanyExecutorApplicationTests.falg = 1;
);
threadA.start();
Thread threadB = new Thread(new Runnable()
@Override
public void run()
int i = 0;
while(i < 100)
if(KinglexCompanyExecutorApplicationTests.falg == 1)
i = i + 2;
System.out.println(i);
KinglexCompanyExecutorApplicationTests.falg = 0;
);
threadB.start();
2 三个线程交替打印a、b、c
static volatile int falg = 0;
@Test
public void test001()
Thread threadA = new Thread(new Runnable()
@Override
public void run()
int i = 0;
while(i < 100)
if(KinglexCompanyExecutorApplicationTests.falg == 0)
i = i + 1;
System.out.println('a');
KinglexCompanyExecutorApplicationTests.falg = 1;
);
threadA.start();
Thread threadB = new Thread(new Runnable()
@Override
public void run()
int i = 0;
while(i < 100)
if(KinglexCompanyExecutorApplicationTests.falg == 1)
i = i + 1;
System.out.println('b');
KinglexCompanyExecutorApplicationTests.falg = 2;
);
threadB.start();
Thread threadC = new Thread(new Runnable()
@Override
public void run()
int i = 0;
while(i < 100)
if(KinglexCompanyExecutorApplicationTests.falg == 2)
i = i + 1;
System.out.println('c');
KinglexCompanyExecutorApplicationTests.falg = 0;
);
threadC.start();
