我需要创建一个基类,它实现了许多方法的接口,例如下面的例子.

是否有更简单的方法来委派这些方法调用而无需创建大量重复方法？

public class MultipleInterfaces implements InterFaceOne, InterFaceTwo {

    private InterFaceOne if1;
    private InterFaceTwo if2;

    public MultipleInterfaces() {
      if1 = new ImplementingClassOne();
      if2 = new ImplementingClassTwo();
    }

    @Override
    public void classOneMethodOne { if1.methodOne(); }
    @Override
    public void classOneMethodTwo { if1.methodTwo(); }
    /** Etc. */


    @Override
    public void classTwoMethodOne { if2.methodOne(); }
    @Override
    public void classTwoMethodTwo { if2.methodTwo(); }
    /** Etc. */

}

我正在研究用于并行计算JavaSeis.org的软件开发框架.我需要一个强大的机制来报告线程异常.在开发过程中,了解异常的来源具有很高的价值,因此我想在过度报告方面犯错误.我也希望能够在线程中处理Junit4测试.方法是否合理或有更好的方法吗？

import java.util.concurrent.Callable;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;

public class TestThreadFailure {

  public static void main(String[] args) {
    int size = 1;
    ExecutorService exec = Executors.newFixedThreadPool(size);
    ThreadFailTask worker = new ThreadFailTask();
    Future<Integer> result = exec.submit(worker);
    try {
      Integer value = result.get();
      System.out.println("Result: " + value);
    } catch (Throwable t) {
      System.out.println("Caught failure: " + t.toString());
      exec.shutdownNow();
      System.out.println("Stack Trace:");
      t.printStackTrace();
      return;
    }
    throw new RuntimeException("Did not catch failure !!");
  }

  public static class ThreadFailTask implements Callable<Integer> {
