1.完成了查询学生信息

//查询学生信息
static void selectStudent(ArrayList<Student> array) {
Scanner scanner=new Scanner(System.in);
String id;
while(true) {
System.out.println("请输入要查询的学生学号");
id=scanner.nextLine();
boolean flag=false;
for(int i=0;i<array.size();i++) {
Student student=array.get(i);
if(student.getStunumber().equals(id)) {
Student s=array.get(i);
System.out.print(s.getStunumber()+"\t"+s.getName()+"\t"+s.getAge()+"\t");
boolean sex=s.isSex();
if(sex==false) {
System.out.print("男");
}
else {
System.out.print("女");
}
System.out.print("\t"+s.getScore()+"\n");
flag=true;
break;
}
}
if(flag) {
break;
}
else {
System.out.println("未查询到，请重新输入: ");
break;
}
}
}
