❶ java课程程序设计报告 课题：小学算术运算测试程序
这个你可找一个简单计算器就可以，能实现你的要求
❷ 自动出题系统（java 课程设计） 谁有 发一个给我 要完整的源代码！！！[email protected] 好的话加分
我有一个 是这样写的你看一下 是否满足你的条件
他是一个有登陆 显示在线考试的系统 用户登陆之后 会有一个菜单选项 选择考试
进入考试界面 显示每题 用按钮点击找到下一题 做完之后 打分
❸ JAVA课程设计题目答案
问题呢。。。。？？？？
❹ java课程设计 小学生数学闯关游戏
大致整理了一下你的需求~~最便宜的也得2000块钱才能做吧~
最基本需要的功能如下
1：教师登陆出题、查看成绩
2：学生登陆答题、计时、判分
3：账号管理
❺ 用Java做出 小学生数学练习题目自动生成系统,要完整的可以运行的界面之类的
能够帮你完成这个题目,QQ?Email?
小学生数学练习题目自动生成系统
❻ 《Java》期末课程设计
import java.util.Scanner;
public class InputProcess {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);//读取来用户的输入源
StringBuffer text = new StringBuffer();//保存用户的输入
System.out.println("请输入： ");
text.append(in.nextLine());//读入用户的输入
String result = text.toString();
result = result.replaceAll("word", "world");//将子字符串“word”替换为字符串“world”
result = result.replaceAll("this", "");//删除所有的子字符串“this”
System.out.println(result);
}
}
希望能帮到你，仍有问题可以HI我~！
❼ Java课程设计小学生算数测试程序APPLET版
明白算法就不难实现了。首先生成考题：十以内的两个数字随机组合，小专学是没有负数的，0不能属做除数等细节考虑到，生成后。学生输入答案，判断是否和执行结果一致就行了。applet只是java的一种呈现方式，核心算法都一样。如果还不清楚，可以到码源网联系客服定制开发 源码交易平台
❽ 小学生数学测试软件的编写java
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Random;
public class Caculate {
private enum CalType {
Add,
Minus,

} else if("*".equals(type)){
return Multiply;
} else if("/".equals(type)){
return Divide;
} else {
throw new Exception("calulate type invalid!");
}
}
}
/**
* @param args
* @throws IOException
*/
public static void main(String[] args) throws IOException {
// TODO Auto-generated method stub
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
do{
System.out.print("选择题型：(+,-,*,/): ");
String strType = in.readLine();
try {
CalType calType = CalType.getType(strType);
System.out.print("题目数量： ");
int num = Integer.parseInt(in.readLine());
int count = 0;
Random rand = new Random();
while(count++ < num){
int number1 = rand.nextInt(1000);
int number2 = rand.nextInt(1000);
double result,answer;
result = 0;
System.out.println("第" + count + "题：" );
switch(calType){
case Add:
System.out.print(number1 + "+" + number2 + "=");
result = number1 + number2;
break;
case Minus:
System.out.print(number1 + "-" + number2 + "=");
result = number1 - number2;
break;
case Multiply:
System.out.println(number1 + "*" + number2 +"=");
result = number1 * number2;
break;
case Divide:
System.out.println(number1 +"/" + number2 + "=");
result = (double)number1 / number2;
}
answer = Double.parseDouble(in.readLine());
if(answer == result){
System.out.println("你答对了！");
}else{
System.out.println("你答错了，正确答案：" + result);
}
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}while(true);
}
}
