为什么会出现此“越界”错误？

Question

当我使用此编码来获取用户输入时，出现了键外错误。 noOfJudges的用户输入是数组将noOfJudges多长时间。 为每个法官输入分数并进行测试，看分数是否在1到10之间。
码：

  double [] scores = new double [noOfJudges];

  System.out.print("Please enter the next score: ");
  for(scoreEntry = 0; scoreEntry < scores.length; scoreEntry++)
      scores[scoreEntry]=console.nextDouble();
  System.out.println();


      while((scores[scoreEntry] < MIN_SCORE)||(scores[scoreEntry] > MAX_SCORE))
      {
         System.out.print("Please reenter the score (must be between 1.0 and 10.0, in .5 increments): ");
         scores[scoreEntry] = console.nextDouble();
         System.out.println();
      }

如果有人想成为一个伟大的人物，是否有一种方法可以检查数字是否介于1到10之间并且仅以0.5为增量？

Answer 1

您应该在for循环或reset scoreEntry使用局部变量，因为在for循环的 scoreEntry等于数组的长度，这不是有效的索引...

Answer 2

for循环结束后，

做一个System.out.println(scoreEntry);

这就是你的答案:)

最好，

Answer 3

您必须忘记一对{}

double[] scores = new double[noOfJudges];

System.out.print("Please enter the next score: ");
for(scoreEntry = 0; scoreEntry < scores.length; scoreEntry++) {
    scores[scoreEntry] = console.nextDouble();
    System.out.println();
    while((scores[scoreEntry] < MIN_SCORE) || (scores[scoreEntry] > MAX_SCORE)){
        System.out.print("Please reenter the score " + 
            "(must be between 1.0 and 10.0, in .5 increments): ");
        scores[scoreEntry] = console.nextDouble();
        System.out.println();
    }
}
