Java 方法返回哈希码，我想要返回一个值

Question

我在尝试 return 单个值时不断取回哈希值我已经尝试了很多不同的方法但还没有成功

private static void displayHighestScores(int[] walkingScores, int[] groomingScores,
        int[] overAllscore, int  numberOfCompetitors)
{
    findMax(walkingScores, groomingScores,  overAllscore, numberOfCompetitors);
    printTitle();
    System.out.println("The best walking score is " + walkingScores.toString());
    System.out.println("The best grooming score is " + groomingScores.toString());
    System.out.println("The best overall score is " + overAllscore.toString());



}
private static int findMax(int[]walkingScores,int[] groomingScores,int[] overAllscore, int numberOfCompetitors){
    int i;
    int lowest = Integer.MIN_VALUE;
    for (i = 0; i < numberOfCompetitors; i++){
        if (walkingScores[i] > lowest)
            lowest = walkingScores[i];
    }
    return i;

}


it is printing out this :

最好的美容分数是[I@28f553e3

总分最好的是[I@2567117

按Return继续

Answer 1

方法很好，就是你打印错了。

不要在数组上调用 .toString()，而是使用 Arrays.toString(array)，例如

System.out.println("The best walking score is " + Arrays.toString(walkingScores));
