透過try catch是無法捕捉子執行緒異常的,Thread物件提供了setUncaughtExceptionHandler(Thread.UncaughtExceptionHandler eh)方法用來取得執行緒中產生的例外狀況。
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"); } } }
