Java -循环遍历多个数组(字符串与"array type“不匹配)

int[] array1 = {1, 2, 3};
String[] array2 = {"a", "b", "c"};
double[] array3 = {1.1, 2.2, 3.3};

// 嵌套循环遍历多个数组
for (int i = 0; i < array1.length; i++) {
    System.out.println(array1[i]);
    for (int j = 0; j < array2.length; j++) {
        System.out.println(array2[j]);
        for (int k = 0; k < array3.length; k++) {
            System.out.println(array3[k]);
        }
    }
}

import java.util.Arrays;
import java.util.stream.Stream;

int[] array1 = {1, 2, 3};
String[] array2 = {"a", "b", "c"};
double[] array3 = {1.1, 2.2, 3.3};

// 将多个数组转为Stream对象，使用flatMap进行扁平化操作
Stream<Object> stream = Stream.of(array1, array2, array3)
        .flatMap(Arrays::stream);

// 遍历打印每个元素
stream.forEach(System.out::println);
