I seriously probation the book today, first of all, according to the author's habit of reading, like to look at the front of the first part. In the preface, the author put a road map of learning Java, which is a standard learning process. But why put a design pattern in the programming advanced, and then the next is the abstract class and interface, package and access rights (this name and

Practice 1:1 people very unlucky, accidentally smashed a woman's basket of eggs. Ask how many eggs are in the basket for compensation.The woman said, she is not clear, only remember to take two each time one, each take 3 is left 2,Take 5 each time Left 4, if each egg 1 yuan, ask you to help programming, calculate the minimum should pay how much money?Requirements: With the Loop statement implementation, directly print out the results do not give points.Package Com.cdp.project;public class Task1
