Thread.currentThread().getName 和 this.getName有什么区别？5
直接上代码吧import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import java.util.concurrent.ThreadFactory; class UnCatchExceptionThread extends Thread{ public UnCatchExceptionThread(String name){ this.setName(name); } @Override public void run() { System.out.println("Thread name is: " + this.getName()); throw new RuntimeException(); } } class UnCatchExceptionHandler implements Thread.UncaughtExceptionHandler{ @Override public void uncaughtException(Thread t, Throwable e) { System.out.println("catch " + e + " from " + t.getName()); } } class HandlerFactory implements ThreadFactory{ @Override public Thread newThread(Runnable r) { Thread t = new Thread(r); t.setUncaughtExceptionHandler(new UnCatchExceptionHandler()); return t; } } public class CaptureException { public int i; /** * @param args */ public static void main(String[] args) { ExecutorService exec = Executors.newCachedThreadPool(new HandlerFactory()); exec.execute(new UnCatchExceptionThread("Gemoji")); } }
输出如下：引用
Thread name is: Gemoji
catch java.lang.RuntimeException from Thread-1
而把System.out.println("Thread name is: " + this.getName());
换成System.out.println("Thread name is: " + Thread.currentThread().getName());
之后，输出就变成了：引用
Thread name is: Thread-1
catch java.lang.RuntimeException from Thread-1
这是为什么呢？2011年12月28日 21:56
