用Java语言写一个用哈夫曼编码对任意一个文件的内容进行编解码的程序。

只要自己再加个类Tree就可以了。 代码如下： public class Tree { double lChild, rChild, parent; public Tree (double lChild, double rChild, double parent) { this.lChild = lChild; this.rChild = rChild; this.parent = parent; } public double getLchild() { return lChild; } public void setLchild(double lChild) { this.lChild = lChild; } public double getRchild() { return rChild; } public void setRchild(double rChild) { this.rChild = rChild; } public double getParents() { return parent; } public void setParents(double root) { this.parent = root; } }
