觉得楼主没有把题目描述清楚。

汉语没学好。

第二题是很经典的C语言的例题嘛
去翻翻那本Ｃ的课本就会了

不好意思！前面没注意！现在应该清楚了吧！

是啊....真有点想回去读小学....

没课本啦...都不知道到那去了...
这题我是这样做的
String str = "dcba";
Map tree = new TreeMap();
for (int i = 0; i < str.length(); i++) {
char ch = str.charAt(i);
if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' && ch <= 'Z')) {
if (!tree.containsKey(ch)) {
tree.put(ch,1);
} else {
Integer in = (Integer) tree.get(ch) + 1;
tree.put(ch, in);
}
}
}
Iterator tit = tree.keySet().iterator();
while (tit.hasNext()) {
Object temp = tit.next();
System.out.print(temp.toString() + "(" + tree.get(temp) + ")");
}


不知道你有没有更简单的方法

还是没搞懂你的题是啥意思!!

第一个题用集合并实现排序接口不可以么?

应该可以的,用冒炮排序应该更好点！
