发帖数: 1229 | 1 作业，创建rectangle class， 要求 throw exceptions， 我的code如下：
public class rectangle extends Shape{
public Rectangle ()
{
this(Shape.DEFAULT_SIZE, Shape.DEFAULT_SIZE);
}
public Rectangle (double newLength, double newWidth)
{
this(Rectangle.RECTANGLE_NAME, newLength, newWidth);
}
protected Rectangle (String newName, double newLength, double newWidth)
{
super (newName);
try
{
this.setLength (newLength);

发帖数: 457 | 2 Exception本身就是implements了Throwable了的，你extends和implements达到的效果
都是一样的。
我试了你的code,没有你说的问题啊？
Shape.java:
public class Shape {
public static final double DEFAULT_SIZE = 1.0;
private String name;
public Shape(String name) {
this.name = name;
}
}
Rectangle.java:
public class Rectangle extends Shape {
public static final String RECTANGLE_NAME = "Rectangle";
private double length;
private double width;
public Rectangle ()
{

对了,我这个还有个WEIGHT,就是如果是偶次对换出来的就是1,否则是-1
fullorder[object_, result_, weight_] :=
Module[{NewObject, NewResult, NewWeight, NewLength, objectlength,
firstobject, i, j,},
objectlength = Length[object];
If[objectlength == 1, result = {object}; weight = {1},
firstobject = object[[1]];
NewObject = Delete[object, 1];
NewLength = Factorial[objectlength - 1];
fullorder[NewObject, NewResult, NewWeight];

发帖数: 203 | 5 I am confused here: it seems you may erase some of the original characters
in the string. For example, if newLength < length, then starting from the
end, you will overwrite the characters that have not been processed. |

发帖数: 559 | 6 有bug吧？如果newlength < length，你中间把原值覆盖了。前面一位说的先去A，再添
B应该是正确解法吧。 |

发帖数: 4889 | 7 int[] buffer
长度不够时
int[] oldBuffer = buffer;
buffer = new int[newLength];
copy oldBuffer to buffer
java数组是动态new的，又不是声明多长是多长，怕什么长度不够？ |

发帖数: 56 | 8 这个也不行，但是我发现了http://www.tug.org/TeXnik/mainFAQ.cgi?file=space/space
的一处错误，校正后现在我能够修改章节标题上下边距了，但是我还是不能修改table
of contents,list of figure,list of table 这几个标题的上下边距！！！
还请指点
附上正确的程序
其实网上的程序只是缺了一个％。。。
