初学Java时，数组排序易混淆，尤其是调用sort库函数的使用方法。 1、 在已安装JDK和Eclipse的电脑上，若未安装请先完成安装。启动Eclipse，创建一个Java项目，项目名称可自定义，JRE版本选择无限制，任意版本均可。 4、 将数组按升序排列，默认从小到大排序。

I am a little bit stuck. for homework, I need to find the smallest String and sort a list of Strings according to their sizes. I don't think I need to use array since it is not covered in class yet.
