java小程序编写

微信公开课小程序热门讨论「java小程序编写」最新回复-楼主，以下是我的实现方式，看看是不是你想要的，哪里不清楚的可以单独M我。importjava.util.Arrays;importjava.util.Comparator;publicclassStudent{privateintid;privateStringname;privateStringbirthday;publicStudent(intid,Stringname,Stringbirthday){this.id=id;this.name=name;this.birthday=birthday;}publicstaticvoidmain(String[]args){Students1=newStudent(1,张三,19830122);Students2=newStudent(2,张一,19830121);Students3=newStudent(3,张笑一,19830127);Students4=newStudent(4,张含一,19830101);Student[]students={s1,s2,s3,s4};//将4个学生对象装入数组中//现根据出生日期对数组元素进行排序，由于String已经实现了Comparable接口，可以直接利用compareTo方法进行比较Arrays.sort(students,newComparatorStudent(){publicintcompare(Studento1,Studento2){returno1.getBirthday().compareTo(o2.getBirthday());}});//打印排序后的结构System.out.println(Arrays.toString(students));Student[]newStudents=newStudent[students.length];inti=0;for(Students:students){if(s.getName().indexOf(一)!=1){newStudents[i]=s;i++;}}//打印搜索出的姓名含“一”的学生System.out.println(Arrays.toString(newStudents));}@OverridepublicStringtoString(){//TODO自动生成方法存根returnStudent姓名:+this.name+,出生日期：+this.birthday;}publicintgetId(){returnid;}publicStringgetName(){returnname;}publicvoidsetId(intid){this.id=id;}publicvoidsetName(Stringname){this.name=name;}publicStringgetBirthday(){returnbirthday;}publicvoidsetBirthday(Stringbirthday){this.birthday=birthday;}}
String:indexOf应该可以满足 更多有关「java小程序编写」的疑问请扫码关注微信公开课+小程序！
