java - 如何将数组存储在单个数组中

Question

如何将数组存储在单个数组中？ 例如我有四个不同的数组，我想将它存储在单个数组 int storeAllArray [] 中，当我调用例如storeAllArray[1] ，我将得到此输出 [11,65,4,3,2,9,7] 而不是单个元素？

int array1 [] = {1,2,3,4,5,100,200,400}; 
int array2 [] = {2,6,5,7,2,5,10};
int array3 [] = {11,65,4,3,2,9,7};
int array4 [] = {111,33,22,55,77};

int storeAllArray [] = {array1,array2,array3,array2}//我想将所有数组存储在数组中

for (int i=0; i<storeAllArray; i++){
   System.out.println(storeAllArray.get[0]); // e.g. will produce --> 1,2,3,4,5,100,200,400 , how can I do this?
}

编辑: 我怎样才能得到这样的输出？

   System.out.println(storeAllArray [0])  --> [1,2,3,4,5,100,200,400]; 
    System.out.println(storeAllArray [1])  --> [2,6,5,7,2,5,10];
    System.out.println(storeAllArray [2])  --> [11,65,4,3,2,9,7];
    System.out.println(storeAllArray [2])  --> [111,33,22,55,77];

Answer 1

int array1 [] = {1,2,3,4,5,100,200,400};
int array2 [] = {2,6,5,7,2,5,10};
int array3 [] = {11,65,4,3,2,9,7};
int array4 [] = {111,33,22,55,77};
int[] storeAllArray [] = {array1,array2,array3,array4};

for (int[] array : storeAllArray) {
    System.out.println(Arrays.toString(array));
}

在 Java 5 及更高版本中，打印

[1, 2, 3, 4, 5, 100, 200, 400]
[2, 6, 5, 7, 2, 5, 10]
[11, 65, 4, 3, 2, 9, 7]
[111, 33, 22, 55, 77]

在 Java 5 之前，你应该使用

    System.out.println(Arrays.asList(array));
