Use two methods to modify the program to compile and run the right: (1) Sorter class is defined as the static inner class, (2) the use of external when creating the Sorter object class a reference,
Finally, using an anonymous inner class to rewrite the program to realize the same function,
Requirements: submit the program code and operation result screenshots,

Please first learn to code,
CodePudding user response:
Main is a static method cannot directly create an inner class inside, so after you polish the inner classes to increase the static can compile and run,Two way,
1, create a public methods, implementation logic in this aspect, and then the main aspects of new a Pockes object invocation,
2, create the object is modified to: Sorter s=new Pockets () new Sorter ();
