一段文字中替换所有汉字的数字为阿拉伯数字

用数字计算出来结果，方便快速，容易理解。

public void matching(){//^[^一二三四五六七八九十百千万块元][一二三四五六七八九十百千万块元]$/int index = 0;List<String> list = new ArrayList<String>();String mParam = "";while(true){mParam = check(index);if(mParam == null){break;}if(!mParam.equals("")){list.add(mParam);}index++;}String param = "";for (int i = 0; i < list.size(); i++) {param = list.get(i);toConver(param);}}//五百二十三public int toConver(String param){int index = 0,next,f =1,s =1,r=0;char m,n;while(index < param.length()){//得到index位置的字符:三m = param.charAt(index);//一到十if(com.indexOf(m) >= 0){//初始化一下单位s = 1;//转换数字后的值：3f = number[com.indexOf(m)];next = index + 1;if(next < param.length()){n = param.charAt(next);if(un.indexOf(n)>= 0) {index++;s = numberUn[un.indexOf(n)];}}r = f * s + r;}index++;}System.out.println(r);return r;}public String check(int index){int i = index+1;int j = i;if(i >= count){return null;}String f = String.valueOf(text.charAt(index));String s = String.valueOf(text.charAt(i));if(index == 0 && compare.indexOf(s) >= 0){i = getLast(i,s);return text.substring(index,i);}else if(compare.indexOf(f) < 0 && compare.indexOf(s) >= 0){i = getLast(i,s);return text.substring(j,i);}return "";}/** * 返回截止的位置 * @param i 下一个位置 * @param s 下一个位置对应的大写数字 * @return */public int getLast(int i,String s){while(true){i++;if(i >= text.length()){break;}s = String.valueOf(text.charAt(i));if(compare.indexOf(s) < 0){break;}}return i;}

替换法，暂时没有实现零。比较麻烦，耗时，弃用
