java String 中 startsWith() 对字符串开头进行过滤 endsWith()对字符串结尾进行过滤_不废话快上车

public class Main {

    public static void main(String[] args) {

        String[] strs={
                "#abc",
                "abcd",
                "#abcde",
                "#abcdef",
                "abcdefg",
                "abcdefgh#",
                "abcdefghi#",
        };
        System.out.println("开头有#:");
        for(String str:strs)
        {
            if(str.startsWith("#"))
            {
                System.out.println(str);
            }
        }
        System.out.println("结尾有#:");
        for(String str:strs)
        {
            if(str.endsWith("#"))
            {
                System.out.println(str);
            }
        }
    }
}public class Main {
