Create an array, and then create a random number in an array, and obtain values will he removed in rewriting in the array gain

Import the Java. Util. ArrayList;

Not optimization like this

Well I study out

Bosses see what place can be optimized under

The individual feels you have a problem in the remove function, because want to remove in the array, but you didn't hand in the array function, don't know how to remove you, I see you this array is a local variable, function get less than, so there should be no removal, you can print the array, removed
