DZF 字符串數組的處理-統計問題

將一批單詞存入一個字符串數組中，例如：{"good","word","work","mean","thank","me","you","or","and"}
進行如下處理：
1) 統計含有子字符串or的單詞個數；
2) 統計以字符m開頭的單詞個數。
3）統計長度爲4的單詞個數。

代碼如下：

public class ZFCtongji{
	public static void main(String args[]) {
		String s[]= {"good","word","work","mean","thank","me","you","or","and"};
		int or=0;
		int m=0;
		int f=0;
		for(int i=0;i〈s.length;i++)
		{
			if(s[i].contains("or"))
				or++;
			else {}
			if(s[i].startsWith("m"))
				m++;
			else {}
			if(s[i].length()==4)
				f++;
			else {}
			
		}
		System.out.println("字符串中含有or的單詞個數爲："+or);
		System.out.println("以m開頭的單詞個數爲："+m);
		System.out.println("長度爲4的單詞的個數爲："+f);
	}
}
