本篇文章给大家谈谈java输出成绩单代码，以及java打印成绩对应的知识点，希望对各位有所帮助，不要忘了收藏本站喔。

求JAVA源代码
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
public class GradeStatistic {
public static void main(String[] args) {
GradeStatistic gs = new GradeStatistic();
ListMark list = new ArrayListMark();
float sum = 0;
while(true){
Scanner sc = new Scanner(System.in);
System.out.print("Please input student name: ");
String name = sc.nextLine();
if(name.equals("end")){
break;
}
System.out.print("Please input student score: ");
float score = sc.nextFloat();
sum += score;
list.add(gs.new Mark(name, score));
}
float max = list.get(0).getScore();
float min = list.get(0).getScore();
for(Mark mark: list){
if(max mark.getScore()){
max = mark.getScore();
}
if(min mark.getScore()){
min = mark.getScore();
}
}
float average = sum / list.size();
System.out.println("Average is: " + average);
System.out.println("Max is: " + max);
System.out.println("Min is: " + min);
}
private class Mark{
private String name;
private float score;
public Mark(String name, float score){
this.name = name;
this.score = score;
}
public String getName() {
return name;
}
public float getScore() {
return score;
}
}
}
----------------------
Please input student name: Zhang san
Please input student score: 100
Please input student name: Li Si
Please input student score: 91
Please input student name: Ec
Please input student score: 35
Please input student name: ma qi
Please input student score: 67
Please input student name: end
Average is: 73.25
Max is: 100.0
Min is: 35.0
java中用if做成绩单
如果可以修改，最好把java改成javascript
你的程序没有问题（可能思路有些问题，比如90怎么可能是优秀跟良好的）就是多了一个分号
html
head
title程序结构3SWITCH/title
/head
body
script language="javascript"
function c(form)
{var a=form.cnumber.value;
//{这里去掉
if(a=90a=100)
{document.write("优秀");}
if(a=80a=90)
{document.write("良好");}
if(a=70a=80)
{document.write("中等");}
if(a=60a=70)
{document.write("及格");}
if(a=60){document.write("不及格");}
}
/script
form
input name="cnumber" type="text" /br /
input name="button" type="button" onclick="c(form)" value="提交" /
/form
/body
/html
这两道题代码怎么写java？
创建一个名字为“ReportCard”的类，然后用下边的内容全部替换掉，你会成为全班最亮的仔。
import java.util.HashMap;
/**
* 学生成绩单
*/
public class ReportCard {
public static void main(String[] args) {
ReportCard reportCard = new ReportCard("张三", "070602213");
reportCard.set("语文", 80.0);
reportCard.set("数学", 59.5);
reportCard.set("英语", 66.0);
reportCard.set("java", 80, 99.0);
reportCard.set("数据库", 80, 66.0);
reportCard.set("毛概", null);
System.out.println(reportCard.getStudentName() + "语文分数:" + reportCard.get("语文"));
System.out.println(reportCard.getStudentName() + "数学考核结果:" + (reportCard.isPassed("数学") ? "合格" : "不合格"));
System.out.println(reportCard.getStudentName() + "期末是否挂科：" + (reportCard.isAllPassed() ? "否" : "是"));
}
// 学生姓名

return courseResult == null ? Double.NaN : courseResult.getStudentScore();
}
public void set(String courseName, Double studentScore){
