编写一个student，要求：1.定义4个字段name,stuNum,Specinaity,age

.......什么意思，不懂，那就定义呗......

public class Student {
private String name;
private int stuNum;
private String Specinaity;
private int age;
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getSpecinaity() {
return Specinaity;
}
public void setSpecinaity(String specinaity) {
Specinaity = specinaity;
}
public int getStuNum() {
return stuNum;
}
public void setStuNum(int stuNum) {
this.stuNum = stuNum;
}
}

public class student{
public student(){

}

public String name;
public int stuNum;
public String specinaity;
public int age;
....
}
