public class Student{
private String name;
private String studentNo;
private float score;
//get方法
//set方法
public static void main(String[] args){
//你可以用學生數組或者List<Student>來存數據
//我示範一下用數組存數據的 當然你用list來存的話 後面的比較 更加簡單 只需要
//實現一個比較器即可
Student[] students = new Student[2]
Student a =new Student();
a.setName("a");
a.setStudentNo("001");
a.setScore(98);
students[0]=a;
Student b = new Student();
b.setName("b");
b.setStudentNo("002");
b.setScore(87);
sudents[1] = b;
。。。。。。
//然後用冒泡排序根據學生的成績判斷 演算法你自己決定 冒泡還是挺好用的
for(int i =0,len =students.length ;i<len;i++){
for(int j=i+1,len;=students.length;j<len;j++){
if(students[i].getScore()>students[j].getScore()){
Student temp =students[i];
students[i] = students[j];
students[j]=temp;
}
}
}
///最後輸出結果
for(){
System.out.println();
}
}
② Java中計算學生的平均身高
public class Compute {
class Student {// 學生類
private double height;
Student(double height) {
this.height = height;
}
public double getHeight() {
return height;
}
public void setHeight(double height) {
this.height = height;
}
}
class Height {// 方法類
public double compute(Student[] students) {
int count = students.length;
double sum = 0;
for (Student student : students) {
sum += student.getHeight();
}
double result = sum / count;
return result;
}
}
class TestHeihgt {// 測試類
public void test() {
Student[] students = { new Student(170), new Student(160), new Student(165) };
Height height = new Height();
double avgHeight = height.compute(students);
System.out.println("學生平均身高是:" + avgHeight);
}
}
public static void main(String[] args) {
TestHeihgt testHeihgt = new Compute().new TestHeihgt();
testHeihgt.test();
}
}
純手打,測試可用!
