Answer 1

声明数组这样的：

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

和使用的项目是这样的：

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

您可以使用一个多维数组：

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

那么你可以做到这一点通过声明的地图，像这样Map<String, MySweetObject>或创建一个List<String>并把每个列表放入数组中。

Answer 4

你需要一个交错数组，这是一个数组的数组：

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

然后，您可以访问的内容，因为这：

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
