Java 线程死锁
java中的死锁是多线程处理的一部分。当线程正在等待由另一个线程获取的对象锁而第二个线程正在等待由第一个线程获取的对象锁时，可能会发生死锁。由于两个线程都在互相等待释放锁，因此该条件称为死锁。
Java中的死锁示例
public class TestDeadlockExample1 {
public static void main(String[] args) {
final String resource1 = "ratan jaiswal";
final String resource2 = "vimal jaiswal";
// t1 tries to lock resource1 then resource2 Thread t1 = new Thread() {
public void run() {
synchronized (resource1) {
System.out.println("Thread 1: locked resource 1");
try {
Thread.sleep(100);
}
catch (Exception e) {
}
synchronized (resource2) {
System.out.println("Thread 1: locked resource 2");
}
}
}
}
;
// t2 tries to lock resource2 then resource1 Thread t2 = new Thread() {
public void run() {
synchronized (resource2) {
System.out.println("Thread 2: locked resource 2");
try {
Thread.sleep(100);
}
catch (Exception e) {
}
synchronized (resource1) {
System.out.println("Thread 2: locked resource 1");
}
}
}
}
;
t1.start();
t2.start();
}
}
Output: Thread 1: locked resource 1 Thread 2: locked resource 2
