怎么写大象进冰箱java编程

创建一个冰箱的class，三个方法：打开冰箱门，放进去东西，关上冰箱门。

创建一个大象的class

创建冰箱和大象的对象，调用冰箱的三个方法将大象装进去。。。

开门----->放大象--------->关门

然后没了。

具体的自己参考，以定义学生类为例

package js.topcom

public class Student {

//属性包括姓名，学号，语文成绩，数学成绩，英语成绩

private String name

private String id

private int chn_score

private int math_score

private int en_score

//方法包括输出数据，设置姓名和学号，设置三门课程的成绩，求总成绩和平均成绩

public void diplay(){

System.out.println("the student name is: " + this.name)

System.out.println("the student id is: " + this.id)

System.out.println("the student chinese score is: " + this.chn_score)

System.out.println("the student math score is: " + this.math_score)

System.out.println("the student english score is: " + this.en_score)

System.out.println("the student total score is: " + this.get_total_score())

System.out.println("the student average score is: " + this.get_avg_score())

}

public String getName() {

return name

}

public void setName(String name) {

this.name = name

}

public String getId() {

return id

}

public void setId(String id) {

this.id = id

}

public int getChn_score() {

return chn_score

}

public void setChn_score(int chnScore) {

chn_score = chnScore

}

public int getMath_score() {

return math_score

}

public void setMath_score(int mathScore) {

math_score = mathScore

}

public int getEn_score() {

return en_score

}

public void setEn_score(int enScore) {

en_score = enScore

}

public int get_total_score(){

return this.chn_score + this.en_score + this.math_score

}

public int get_avg_score(){

return this.get_total_score() / 3

}

public static void main(String[] args) {

Student stu = new Student()

stu.setName("baidu")

stu.setId("123")

stu.setChn_score(89)

stu.setEn_score(98)

stu.setMath_score(88)

stu.diplay()

}

}
