[Java] 纯文本查看 复制代码

		HashMap<Character,Integer> hashMap = new HashMap<>();
		String text  ="qqqwwwweeeee";
		char[] charArray = text.toCharArray();
		for (char c : charArray) {
			if (hashMap.containsKey(c)) {
				hashMap.put(c, hashMap.get(c)+1);
			}else{
				hashMap.put(c, 1);
			}
		}
		System.out.println(hashMap);

完全看不懂,这是什么鬼
