4.提供属性不同 ArrayList提供一个size()方法来告诉你当前时间点ArrayList存储了多少个元素。size() 总是和length不同的,它也是ArrayList的容量。 Array仅仅提供一个length属性,告知Array里有多少个插槽,即可以存储多少个元素,但它没有提供任何方法来告诉你哪些插槽是满的,哪些是空的,即当前元素的个数。 5.性能不...
// Size the Java array with a set of known valuesint[]arraySizeExample= new{0,1,1,2,3,5,8}; In this case, the size of the Java array is 7. You use the Java array’s length property to print out its size: System.out.println("The Java array size is:" + arraySizeExample.len...

但是ArrayList提供一个size()方法来告诉你当前时间点ArrayList存储了多少个元素。size() 总是和length不同的,它也是ArrayList的容量。 10) Dimension(维度) ArrayList和array的另外一个重要的区别就是array可以使多维度的。如你可以设置一个二维数组或者三维数组,可以使你创在一个特殊的数据结构来代表矩阵或者2D形式(...
