while(runHi < hi && ((Comparable) a[runHi]).compareTo(a[runHi -1]) >=0) runHi++; } returnrunHi - lo; } 这里你应该终于明白了为什么一定要实现comparable接口中的compareTo方法了吧。 如何你没有实现,那么通过接口去找compareTo方法肯定会报错啊(因为这时候找不到compareTo方法,未定义) 结合Tes...
In this tutorial, first, we will compare two array lists using a comparison method in Java. We also apply the same method on Java strings before applying it on array lists. Finally, we demonstrate, how you can sort an unordered array list before comparis
