删除单词后缀

解题思路:

注意事项:

参考代码:

public class Main {

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);

        //输入单词

        String word = scanner.nextLine();

        if (word.endsWith("er") || word.endsWith("ly") ) {

            word = word.substring(0,word.length() - 2);

        }else if(word.endsWith("ing")){

            word=word.substring(0,word.length()-3);

        }

        //endsWith() 方法用于测试字符串是否以指定的后缀结束

        //substring()方法用于截取字符串中的最后几个字符

        System.out.println(word);

    }

}
