System.out.println(list.toString());//[1, 3, 5, 6, 7, 8, 9] 2、usingToString() 按对象的字符串形式做字典排序,即使用toString()返回的字符串按字典顺序进行排序。 List<String> stringList = Lists.newArrayList("zhangsan","lisi","wangwu"); Collections.sort(stringList,Ordering.usingToString())...

For sort the result-set in ascending or descending order, the orderBy method is used. The first argument for the orderBy approach should be the column by which you want to sort, whereas the second argument governs the sort path and can either be asc or desc. ...
