要求用数组，并实现增、删、改、查功能

编写Student（stuno,stuname,stuage）要求实现对象型数组，并实现增、删、改、查功能,并且要求年龄范围在18-85之间

这个很难吗。，，，Student[] stus=new Student[];,,弄一个全局变量，，对这个数组进行增，删，改，，查

看你的这个写法好像不是数组应该是Hibernate对实体的操作

 class Student
{
public int no;
public String name;
public int age;
public Student(int no, String name, int age) { this.no = ni; this.name = name; this.age = age; }
}
class Students
{
private ArrayList<Student> list = new ArrayList<Student>();
public void add(Student st) { list.add(st); }
public void add(int no, String name, int age) { list.add(new Student(no, name, age)); }
public void remove(Student st) { list.remove(st); }
public Student findStudent(int no) { for (Student st : list) if (st.no == no) return st; return null; }
public Student changeStudent(int no, String name, int age) { Student st = findStudent(no); st.name = name; st.age = age; }
public Student findStudentByName(Student name) { for (Student st : list) if (st.name == name) return st; return null; }
}

你要用什么语言实现呢？
