public class RTExcept {
  public static void throwit ( ) {
    System.out.print("throwit ");
    throw new RuntimeException( );
  }
  public static void main(String args[]) {
    try {
      System.out.print("hello ");
      throwit( );
    }
    catch (Exception re) {
      System.out.print("caught ");
    }

    finally {
      System.out.print("finally ");
    }
    System.out.print("after ");y=y1;
  }
  int getX() {return x;}
  int getY() {return y;}
}

Posted by: why Posted on: 2005-06-15 18:43 System.out.print("after "); y=y1; // y and y1 not declared and not static } int getX() {return x;} // int x not declared int getY() {return y;} // int y not declared Why don't you read the error messages from the compiler?

这个朋友也太不应该的，要加把劲啊
其实，
catch(Exception e)和catch(Exception re)都是一夜的，一面的e只不过是标志符的名称，像public static void main(String args[]);里面的args也可以改为别的名字啊。

楼上的建议很好，为什么你不先运行一下，看看问题出现在什么地方啊？
