通过try catch是无法捕获子线程异常的，Thread对象提供了setUncaughtExceptionHandler(Thread.UncaughtExceptionHandler eh)方法用来获取线程中产生的异常。

复制代码 代码如下:
package threads;

import java.lang.Thread.UncaughtExceptionHandler;

public class TextException
{
public static void main(String[] args)
{
Test test = new Test();
test.setUncaughtExceptionHandler(new UncaughtExceptionHandler()
{
public void uncaughtException(Thread t, Throwable e)
{
System.out.println(t.getName() + " : " + e.getMessage());
// TODO
}
});
}

public static class Test extends Thread
{
public Test()
{
}

public void run()
{
throw new RuntimeException("just a test");
}
}
}
