java答题卡编辑代码 java答题卡编辑代码怎么写

阅读以下说明和Java代码，将应填入 (n) 处的字句写在答题纸的对应栏内。

package sleest;

import java.util.Vector;

public class JavaMain {

  世指  static private final int ARRAY_SIZE = 6;

    public static void main(String[] args) {

        VectorInteger theVector = new VectorInteger();

        兆返判for (int cEachItem = 0;  cEachItem  ARRAY_SIZE;  cEachItem++) {

            theVector.add(cEachItem);

        }

        showVector(theVector);

        theVector.removeElementAt(3);

        showVector(theVector);

    }

    public static void showVector(VectorInteger theVector) {

        if (theVector.isEmpty()) {

            System.out.println("theVector is empty.");

            return;

        }

     族改   for (int loop = 0;  loop  theVector.size();  loop++) {

            System.out.print(theVector.get(loop));

            System.out.print(", ");

        }

        System.out.println();

    }

用java swing来编写一个答题器的图形界面该怎么编写？下面附上我的程序

你可以直接用Eclipse或者NetBeans的图形界面，之后添加组件的响搭芦应袭拍就可以啦，很方便的。。。拍枝羡。

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("英语山简", 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"));

}

//芹芹 学生姓嫌唯毕名

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;

}

}

（急）怎么用JAVA做这个题啊。求大神~

代码如下,希望能让帆给你思路：

public class test {

public static void main(String[] args){

int score[]=new int[30];

int sum=0;

for(int i=0; iscore.length; i++)

{

//存储随机坦州雹的分数到score数组中

score[i]=(int) (Math.random()*99+1);

//同事将分数加给sum

sum+=score[i];

}

System.out.println("班级平均迹誉分："+sum*1.0/30);

}

}
