package jhg;import java.util.Scanner;public class AdditionQuiz {public static void main(String[] args) {int number1=(int)(System.currentTimeMillis() % 10);int number2=(int)(System.currentTimeMillis() * 7 % 10);//create a ScannerScanner input=new Scanner(System.in);System.out.print("What is"+number1+"+"+number2+"?");int answer =input.nextInt();System.out.println(number1 + "+" + number2 + "=" + answer + "is+" +(number1+number2==answer));input.close();}}

结果

参考同学的

package jhg;import javax.swing.*;public class TouchType{  public static void main(String args[]){   int num;   String s=(String)JOptionPane.showInputDialog(null,"输入字数","打字成绩判断",                    JOptionPane.PLAIN_MESSAGE,null,null,null);            num=Integer.parseInt(s);          {  if(num>=15&&num<=30)      System.out.println("及格");          if(num>30)            System.out.println("优秀");          if(num<15)        System.out.println("不合格");     }} }

运行结果
