例如，我需要将几个字符串放入一个 java 数组中。

"Dog","Cat","Lion","Giraffe"
"Car","Truck","Boat","RV"

以上每一项都是数组中的 1 个键

array[0] = "Dog","Cat","Lion","Giraffe"
array[1] =  "Car","Truck","Boat","RV"

不知道该怎么做，或者我应该使用数组以外的东西，以及如何获取每个单独的元素，即array[0]"Lion"

谢谢

像这样声明数组：

String [][]array = { 
    { "Dog","Cat","Lion","Giraffe"}, 
    {"Car","Truck","Boat","RV"}
};

并使用这样的项目：

array[0][0]; // this would be "Dog"
array[1][0]; // this would be "Car"

您可以使用多维数组：

String[][] something =
    { 
        { "hello", "kitties" }, 
        {  "i", "am", "a", "pony" } 
    };

好吧，您可以通过像这样声明一个映射来做到这一点，Map<String, MySweetObject>或者创建一个List<String>并将每个列表放入数组中。

您需要一个锯齿状数组，它是一个数组数组：

String [][]array  = { {"Dog","Cat","Lion","Giraffe"}, {"Car","Truck","Boat","RV"}};

然后，您可以按以下方式访问内容：

array[0] // will be the String array {"Dog","Cat","Lion","Giraffe"}
array[1] // will be the String array {"Car","Truck","Boat","RV"}
array[0][2] // Lion
array[1][0] // Car
