用java定义一个学生类，要处理的信息有学号、姓名、年龄、专业。
class Student{private int STU_NUM;private String STU_NAME;private int STU_AGE;public Student(int NUM,String NAME){this.STU_NAME=NAME;this.STU_NUM=NUM;}public Student(int NUM,String NAME,int AGE){this.STU_NAME=NAME;this.STU_NUM=NUM;this.STU_AGE=AGE;}}
完整代码如下，复制到eclipse中运行：
public class StuExam {private String snum;// 学号private String cnum;// 班号private String name;// 姓名private char sex;// 性别private int age;// 年龄// get/set方法用来获取/设置学生实例对象的信息public String getSnum() {return snum;}public void setSnum(String snum) {this.snum = snum;}public String getCnum() {return cnum;}public void setCnum(String cnum) {this.cnum = cnum;}public String getName() {return name;}public void setName(String name) {this.name = name;}public char getSex() {return sex;}public void setSex(char sex) {this.sex = sex;}public int getAge() {return age;}public void setAge(int age) {this.age = age;}public static void main(String[] args) {StuExam stu = new StuExam();// 对学生类实例化// 对学生信息赋值stu.setSnum("0504112");stu.setCnum("02");stu.setSex('女');stu.setName("杨子");stu.setAge(20);// 输出学生信息System.out.println("学号：" + stu.getSnum() + "
班号：" + stu.getCnum()+ "
性别：" + stu.getSex() + "
姓名：" + stu.getName() + "
年龄："+ stu.getAge());}}
public class Student {
private int sno; // 学号
private String sname; // 姓名
private int sage; // 年龄
private String profession; // 专业
public Student() {
}
public Student(int sno, String sname, int sage, String profession) {
super();
this.sno = sno;
this.sname = sname;
this.sage = sage;
this.profession = profession;
}
public int getSno() {
return sno;
}
public void setSno(int sno) {
this.sno = sno;
}
public String getSname() {
return sname;
}
public void setSname(String sname) {
this.sname = sname;
}
public int getSage() {
return sage;
}
public void setSage(int sage) {
this.sage = sage;
}
public String getProfession() {
return profession;
}
public void setProfession(String profession) {
this.profession = profession;
}
@Override
public String toString() {
return "Student [sno=" + sno + ", sname=" + sname + ", sage=" + sage
+ ", profession=" + profession + "]";
}
}
public class Student{
private int stu_no;
private String name;
private int age;
private String profession;
设置下get/set方法
话说你连定义个类都不会 要来有啥用呢
}
JAVA编写一个学生类的程序
在编程中，构建一个学生类是常见的实践任务。首先，定义一个名为Student的实体类，其包含三个属性：学生的名字(name)、年龄(age)和分数(score)。以下是具体实现方式：class Student { public String name;public int age;public double score;public Student(String name, int age, double score) { t...
