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
private String studentName;
// 学生学号
private String studentNumber;
// 成绩单
private HashMapString, CourseResult cards = new HashMap();
public ReportCard() {
}
public ReportCard(String studentName, String studentNumber) {
this.studentName = studentName;
this.studentNumber = studentNumber;
}
public Double get(String courseName){
CourseResult courseResult = cards.get(courseName);
return courseResult == null ? Double.NaN : courseResult.getStudentScore();
}
public void set(String courseName, Double studentScore){
CourseResult courseResult = new CourseResult(courseName, studentScore);
cards.put(courseName, courseResult);
}
public void set(String courseName, double passMark, Double studentScore){
CourseResult courseResult = new CourseResult(courseName, passMark, studentScore);
cards.put(courseName, courseResult);
}
public boolean isPassed(String courseName){
return cards.get(courseName).isPassed();
}
public boolean isAllPassed(){
for(CourseResult cr : cards.values()){
if ( ! cr.isPassed()) {
return false;
}
}
return true;
}
public String getStudentName() {
return studentName;
}
public String getStudentNumber() {
return studentNumber;
}
public void setStudentName(String studentName) {
this.studentName = studentName;
}
public void setStudentNumber(String studentNumber) {
this.studentNumber = studentNumber;
}
/**
* 课程
*/
class Course{
// 课程名称
protected String courseName;
// 及格分
protected double passMark = 60;
public Course(String courseName, Double passMark) {
this.courseName = courseName;
if ( passMark != null) {
this.passMark = passMark;
}
}
}
/**
* 课程成绩
*/
class CourseResult extends Course{
// 学生成绩
private Double studentScore;
public CourseResult(String courseName, Double studentScore) {
this(courseName, null, studentScore);
}
public CourseResult(String courseName, Double passMark, Double studentScore) {
super(courseName, passMark);
this.studentScore = studentScore == null ? Double.NaN : studentScore;
}
public boolean isPassed(){
return studentScore = passMark;
}
public String getCourseName() {
return courseName;
}
public double getPassMark() {
return passMark;
}
public Double getStudentScore() {
return studentScore;
}
}
求JAVA实验代码
public interface Student {
// 该方法用于表示不同阶段的学生在学习数学课程时的不同内容
public abstract void studyMath();
// 该方法用于表示不同阶段的学生的英语水平
public abstract void studyEnglish();
}
public class PrimarySchoolStudent implements Student {
@Override
public void studyMath() {
System.out.println("小学生在学习数学课程时，主要学习加减法，数学表达式等基础知识。");
}
@Override
public void studyEnglish() {
System.out.println("小学生在学习英语时，主要学习词汇，基本句型，基本语法等基础知识。");
}
}
public class MiddleSchoolStudent implements Student {
@Override
public void studyMath() {
System.out.println("中学生在学习数学课程时，主要学习初等函数，代数方程等基础知识。");
}
@Override
public void studyEnglish() {
System.out.println("中学生在学习英语时，主要学习阅读理解，听力理解，口语交流等能力。");
}
}
public class CollegeStudent implements Student {
@Override
public void studyMath() {
System.out.println("大学生在学习数学课程时，主要学习高等数学，概率论，数值计算等专业知识。");
}
@Override
public void studyEnglish() {
System.out.println("大学生在学习英语时，主要学习专业英语，商务英语，英文写作等能力。");
}
}
public class Main {
public static void main(String[] args) {
请问以下问题用java代码来求解应该是怎么写
import java.util.Scanner;
/**

*/
public class Transport {
private static final int BOX_A = 1;
private static final int BOX_B = 3;
private static int count_A;
private static int count_B;
public static void main(String[] args) {
System.out.println("请输入宝物数量：");
int count = new Scanner(System.in).nextInt();
if (count 1 || count 50){
System.out.println("宝物数量输入有误！");
return;
}
for (count_B = 0; count_B = count / BOX_B; count_B++){
count_A = count - count_B * BOX_B;
System.out.println("盒子A装运宝物数量：" + BOX_A + "x" + count_A + "=" + BOX_A * count_A);
System.out.println("盒子B装运宝物数量：" + BOX_B + "x" + count_B + "=" + BOX_B * count_B);
System.out.println("宝物装运总数：" + BOX_A * count_A + "+" + BOX_B * count_B + "=" + (BOX_A * count_A + BOX_B * count_B));
System.out.println("-------------------------");
}
System.out.println("装运方案数为：" + count_B);
}
}
运行结果
谁能帮忙补充完整下列JAVA程序代码？
class A
{
//声明一个float型实例变量a
//声明一个float型类变量b,即static变量b
private float a;
private static float b;
void setA(float a)
{
//将参数a的值赋值给成员变量a
this.a = a;
}
void setB(float b)
{
//将参数b的值赋值给成员变量b
this.b = b;
}
float getA()
{
return a;
}
float getB()
{
return b;
}
void inputA()
{
System.out.println(a);
}
static void inputB()
{
System.out.println(b);
}
}
public class Example
{
public static void main(String args[])
{
//通过类名操作类变量b,并赋值100
//通过类名调用方法inputB()
A.b = 100;
A.inoutB();
A cat=new A();
A dog=new A();
//cat调用方法setA(int a)将cat的成员 a的值设置为200
cat.setA(200);
// cat调用方法setB(int B)将cat的成员 b的值设置400
cat.setB(400);
//dog调用方法setA(int a)将dog的成员 a的值设置为150
dog.setA(150);
//dog调用方法setB(int b)将dog的成员 b的值设置为300
dog.setB(300);
//cat调用inputA（）
//cat调用inputB（）
//dog调用inputA（）
//dog调用inputB（）
cat.inputA();
cat.inputB();
dog.inputA();
dog.inputB();
}
}
