All attributes within a class must be encapsulated in private, and the encapsulated property must provide a setter and getter method4 //3. Multiple construction methods can be provided in a class, but there must be a non-parametric construction method reserved5 //4. No output statements are allowed in the class, and all information output must be given to the output to be tuned6 //5. There is a need to provide a method for obtaining complete information about the object, tentatively: GetInfo; returns string Data7 8 /**9 * Created by Administrator on 2017/6/26.Ten  */ One  A classbook_demo{ -     PrivateString title; -     Private DoubleMoney ; the  -      PublicBook_demo () {} -      PublicBook_demo (String T,Doublem) { -title =T; +Money =m; -     } +  A      Public voidSettitle (String t) { attitle =T; -     } -      Public voidSetmoney (Doublem) { -Money =m; -     } -  in      Public DoubleGetmoney () { -         returnMoney ; to     } +  -      PublicString GetTitle () { the         returntitle; *     } $      PublicString GetInfo () {Panax Notoginseng         return"Name:" + title + "\ T" + -"Price:" + Money + "\ n"; the     } + } A  the  Public classsimple Java class { +      Public Static voidMain (string[] args) { -Book_demo book =NewBook_demo ("Java development", 66.6); $Book.settitle ("Python development");//with modifications $ System.out.println (Book.getinfo ()); - System.out.println (Book.gettitle ()); -  the     } -}
