我如何在java中迭代这两个循环呢？

public class NestedLoopsExample {
    public static void main(String[] args) {
        // 假设有两个数组
        int[] array1 = {1, 2, 3};
        int[] array2 = {4, 5, 6};

        // 外层循环遍历第一个数组
        for (int i = 0; i < array1.length; i++) {
            // 内层循环遍历第二个数组
            for (int j = 0; j < array2.length; j++) {
                System.out.println("array1[" + i + "] = " + array1[i] + ", array2[" + j + "] = " + array2[j]);
            }
        }
    }
}

public class MergedLoopsExample {
    public static void main(String[] args) {
        // 假设有两个长度相同的数组
        int[] array1 = {1, 2, 3};
        int[] array2 = {4, 5, 6};

        // 合并循环遍历两个数组
        for (int i = 0; i < array1.length; i++) {
            System.out.println("array1[" + i + "] = " + array1[i] + ", array2[" + i + "] = " + array2[i]);
        }
    }
}

public class SafeMergedLoopsExample {
    public static void main(String[] args) {
        int[] array1 = {1, 2, 3};
        int[] array2 = {4, 5, 6, 7}; // array2 比 array1 长

        int minLength = Math.min(array1.length, array2.length);

        for (int i = 0; i < minLength; i++) {
            System.out.println("array1[" + i + "] = " + array1[i] + ", array2[" + i + "] = " + array2[i]);
        }
    }
}
