Question

定义学生类student,包含学生的学号,姓名,年龄和三门课程的成级,并计算每个学生的平均成绩和最高分,

Answer 1

这是学生类:
public class Student {

private int xuehao;

private String xingming;

private String xingbie;

private int shuxue;

private int yuwen;

private int yingyu;

public int getShuxue() {
return shuxue;
}

public void setShuxue(int shuxue) {
this.shuxue = shuxue;
}

public String getXingbie() {
return xingbie;
}

public void setXingbie(String xingbie) {
this.xingbie = xingbie;
}

public String getXingming() {
return xingming;
}

public void setXingming(String xingming) {
this.xingming = xingming;
}

public int getXuehao() {
return xuehao;
}

public void setXuehao(int xuehao) {
this.xuehao = xuehao;
}

public int getYingyu() {
return yingyu;
}

public void setYingyu(int yingyu) {
this.yingyu = yingyu;
}

public int getYuwen() {
return yuwen;
}

public void setYuwen(int yuwen) {
this.yuwen = yuwen;
}

public int average(int x,int y,int z){

return (x+y+z)/3;

}

}

这是测试类:
public class TestStudent{
public static void main(String args[]) {
Student st1=new Student();
st1.setShuxue(75);
st1.setYingyu(80);
st1.setYuwen(85);
System.out.println("第一个学生的平均成绩为:"+st1.average(st1.getShuxue(),st1.getYingyu(),st1.getYuwen()));
Student st2=new Student();
Student st3=new Student();
Student st4=new Student();
Student st5=new Student();

}

}
