Update README.md #1

mayfly660 wants to merge 1 commit into doublechaintech:main from mayfly660:patch-1

mayfly660 commented Oct 26, 2020

//在您自己的READ.md中，答案写到下面的位置
public Integer getMaxValue(List valueList){
return (Integer) Collections.max(valueList);
}

//这样做的原因写到下面
collections类是集合的工具类，里面有大量的方法可以操作集合，Collections.max()方法可以获取集合中的最大值；
此公用函数有局限性，它的数据类型是包装类Integer，所以只针对int类型，对其他数据类型不适用。
