还有你说也太笼统了吧!试卷生成和题库管理系统这里面有详细的要求吗?
要求都没有,基本上都不能开发制作的
import java.util.ArrayList;
import java.util.List;
public class Random {
public static void main(String[] args) {
String[] tiMu = new String[20];
for (int i = 0; i tiMu.length; i++) {
tiMu[i] = "第" + (i + 1) + "题";
}
String[] temp = new String[10];
//开始抽取题目
//产生10个随机数
ListInteger list = new ArrayListInteger();
int i;
while(list.size() 10){
i = (int) (Math.random() * 20);
if(!list.contains(i)){
list.add(i);
}
}
for (int j = 0; j list.size(); j++) {
temp[j] = tiMu[list.get(j)];
}
for (int iloop = 0; iloop temp.length; iloop++) {
System.out.print(temp[iloop] + " ");
}
}
}
代码已经写完了,亲测可用,望采纳哦!
//第一题:Test.java
public class Test {
public static void main(String[] args) {
int array[]=new int[10];//声明数组并声明
array[0]=array[1]=1;//赋初始值
System.out.println(array[0]);
System.out.println(array[1]);
for(int i=2;iarray.length;i++){
array[i]=array[i-2]+array[i-1];//用for语句完成相应的运算
System.out.println(array[i]);
}
}
}
//第二题 RandomTest.java
import java.util.Random;//随机数包声明
import java.util.Scanner;//用户输入包声明
public class RandomTest {
public static void main(String[] args) {
Scanner reader=new Scanner(System.in);//声明并创建用户输入对象
System.out.println("我心里有一个0~99之间的数,你猜是什么?");
int i=(int)(Math.random()*100);//生成一个随机数
int input=reader.nextInt();//用户输入
while(i!=input){//判断用户输入的数和随机生数的大小
if(inputi){
System.out.println("小了点,再猜!");
}
if(inputi){
System.out.println("大了点,再猜");
}
input=reader.nextInt();
}
System.out.println("猜对了!");
System.out.println("继续加油!");
}
}
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"));
}
