CodePudding user response:

You use what is enough?
If it is capacity exceeds the maximum limit int? Then their control adopts multi-dimensional array, such as a [] is full, a new b [] []=new xx [Max] []; B [0]=a; B [1]=new xx (Max); Continue to deposit, b [1]
If refers to the length is not enough, the original definition is that a new new an array capacity is enough, then put the old array data copied to the new array,
