在Java中查找两个数组中匹配元素的个数

public class ArrayMatchCount {
    public static int getMatchCount(int[] array1, int[] array2) {
        int count = 0;
        for (int i = 0; i < array1.length; i++) {
            for (int j = 0; j < array2.length; j++) {
                if (array1[i] == array2[j]) {
                    count++;
                }
            }
        }
        return count;
    }

    public static void main(String[] args) {
        int[] array1 = {1, 2, 3, 4, 5};
        int[] array2 = {3, 4, 5, 6, 7};
        int matchCount = getMatchCount(array1, array2);
        System.out.println("匹配元素的个数为：" + matchCount);
    }
}
