一个简单的计算分数的小程序

代码如下：

package Day05; public class ExamGradeDemo {

public static void main(String[] args) {

char[][] answers = {

{'C','B','D','C','A','A','D','C','D','C'},

{'A','C','B','D','C','A','D','C','B','D'},

{'A','C','B','D','B','D','C','A','A','D'},

{'A','C','B','D','C','A','A','D','C','C'},

{'A','C','D','C','A','A','D','D','C','A'},

{'A','C','B','D','C','A','A','D','C','A'},

{'A','C','B','D','C','A','A','D','C','C'},

{'A','C','B','D','C','A','D','C','A','A'}

};

char[] keys = {'A','B','D','C','A','A','D','C','D','A'};

for (int row = 0; row < answers.length; row++) {

int correctCount = 0;

for (int col = 0; col < answers[row].length; col++) {

if (answers[row][col] == keys[col]) {

correctCount++;

}

}

System.out.println("Student " + row + "'s score is " + correctCount);

}

}

}
