java 中文数字排序方法

直接上代码：

首先做个比较器

public Comparator<File> compareByName;

然后就是比较的主要方法

compareByName = new Comparator<File>() {

public int compare(String arg0, String arg1) {
arg1=arg1.replaceAll("-","");//过滤掉文件里的这个符号
arg0=arg0.replaceAll("-","");

arg1 = arg1.replaceAll("一", "11");//这个是让中文数字变成可比较的值

arg0 = arg0.replaceAll("一", "11"));

arg0 = arg0.replaceAll("二", "22");
arg0 = arg0.replaceAll("三", "33");
arg0 = arg0.replaceAll("四", "44");
arg0 = arg0.replaceAll("五", "55");
arg0 = arg0.replaceAll("六", "66");
arg0 = arg0.replaceAll("七", "77");
arg0 = arg0.replaceAll("八", "88");
arg0 = arg0.replaceAll("九", "99");

arg1 = arg1.replace("一", "11");

arg1 = arg1.replaceAll("二", "22");
arg1 = arg1.replaceAll("三", "33");
arg1 = arg1.replaceAll("四", "44");
arg1 = arg1.replaceAll("五", "55");
arg1 = arg1.replaceAll("六", "66");
arg1 = arg1.replaceAll("七", "77");
arg1 = arg1.replaceAll("八", "88");
arg1 = arg1.replaceAll("九", "99");

if (arg0.compareTo(arg1) > 0) {

return 1;
} else if (arg0.compareTo(arg1) < 0) {

return -1;
} else {

return 0;
}
}

public int compare(File arg0, File arg1) {

//将FILE文件 变成STRING再去比较
return compare(arg0.getName(), arg1.getName());
// TODO Auto-generated method stub

}

};

最后 Collections.sort(文件集合LIST, compareByName);

LIST就是已经排序序的了
