/*** 7-1* The program that writes the character interface, accepts a number of positive integers entered by the user,*-1 indicates the end of the input.* Sort the input data in descending order using the sort algorithm* and print the results after each scan* The runtime uses the following different data series to observe its execution results*

Chapter 2 object of everything1. All objects must be created by you1. Where is the storage?1. Register: we cannot control it in the program2. stack: stores basic data and object reference, but the object itself is not stored in the stack, but in the Heap.3. Heap: stores data generated with new4. Static storage: static members defined by Static in objects5. Constant storage: stores constants.6. NON-RAM: hard disk and other permanent storage space2. Spe

Requirements: Write a loop from 1 to 150 and print a value in each row, and then print Foo on multiples of each of the 3 lines, print biz on multiples of 5, and print Baz on multiples of 7.Packagestudy01; Public classFor { Public Static voidMain (string[] args) { for(inti = 1;i) {System.out.print (i); if(i%3==0) {System.out.print ("Foo"); } if(i%5==0)

listIterator(); } public abstract ListIterator listIterator(int index);} This class uses a large number of Iterator for sequential traversal of sets. Because it cannot be randomly located, this class focuses on sequential traversal. If you want to implement a list set by yourself, it is best to inherit this abstract class, in this way, you don't have to bother yourself to implement so many methods. Struct List is a reality of sub-structure Li
