1.编写JAVA类程序片段,定义表示学生的student,包括域“学号”、“班号”、“姓名”、“年龄”;方法“获得学号”、“获得班号”、“获得性别”、“获得姓名”、“获得年龄”、“修改年龄”
2.在上一道题的基础上编写Java 创建student对象的Aplication程序
/////public class Student { private String id;//学号 private int classId;//班号 private String name;//姓名 private String sex;//性别 private int age;//年龄 //设置学生身份证 public void setId(String id) { this.id = id; } //获取学生身份证 public String getId() { return id; } //设置班级id public void setClassId(int classId) { this.classId = classId; } //获取班级ID public int getClassId() { return classId; } //设定年龄 public void setAge(int age) { this.age = age; } //获得年龄 public int getAge() { return age; } //设置姓名 public void setName(String name){ this.name = name; } //获取姓名 public String getName() { return name; } //设置性别 public void setSex(String sex) { this.sex = sex; } //获得性别 public String getSex() { return sex; } ///重写tostring() public String toString() { return “学生号:”+id+" 班级号:"+classId+ " 姓名:"+name+" 性别:"+sex+" 年龄:"+age; } public static void main(String args[]) { Student s = new Student(); s.setId("201190609112"); s.setClassId(111-1); s.setName(张星龙); s.setSex("男"); s.setAge(21); System.out.println(s);///打印内容是重写tostring()后的内容 } }
/////public class Chuangjian {public static void main(String args[]) {Student demoStudent = new Student();System.out.print“学生号:” + demoStudent.getStudentId() + " 班级号:" + demoStudent.getclassId() + " 姓名:" + demoStudent.getStudentName() + " 性别:" + demoStudent.getStudentSex() + " 年龄:"+demoStudent.getStudentAge() );}}class Student {private String studentId="201190609112";private int classId=1111;private String studentName="张星龙";private char studentSex='男';private int studentAge=21;String getStudentId() {return studentId;}int getclassId() {return classId;}char getStudentSex() {return studentSex;}String getStudentName() {return studentName;}int getStudentAge() {return studentAge;}}
运行效果:
