幫妳寫個最簡單的
第壹題：
import java.util.Scanner;
/**

*/
public class JiSuan {
public static void main(String[] args){
Scanner cin = new Scanner(System.in);
int score = 0;
for(int i = 0; i < 10 ; i++){
score = score + (new JiSuan().compute(i,cin))*10;
}
System.out.println("Score :"+score);
}
public int compute(int count,Scanner cin){
int numA = (int) (Math.random()*10)+1;
int numB = (int) (Math.random()*10)+1;
int operate = (int)(Math.random()*4);
if(operate == 0){
System.out.println("Question " + count + ":"+ numA + "+" + numB + "=?");
int myAnswer = cin.nextInt();
int result = numA + numB;
if(myAnswer == result){
return 1;
}else{
return 0;
}
}else if(operate == 1){
System.out.println("Question " + count + ":"+ numA + "-" + numB + "=?");
int myAnswer = cin.nextInt();
int result = numA - numB;
if(myAnswer == result){
return 1;
}else{
return 0;
}
}else if(operate == 2){
System.out.println("Question " + count + ":"+ numA + "*" + numB + "=?");
int myAnswer = cin.nextInt();
int result = numA * numB;
if(myAnswer == result){
return 1;
}else{
return 0;
}
}else{
System.out.println("Question " + count + ":"+ numA + "/" + numB + "=?(no radix point)");
int myAnswer = cin.nextInt();
int result = numA / numB;
if(myAnswer == result){
return 1;
}else{
return 0;
}
}
}
}
第二個：
import java.util.Scanner;
/**
