How do I put a user input int as array length in Java?

Question

If I ask the user for input, how do I put it as the length of an array?

Example:

String teamnum = Input.nextLine();

int teams[]=new int[teamnum];

Look at [`Integer#parseInt()`](http://docs.oracle.com/javase/7/docs/api/java/lang/Integer.html#parseInt(java.lang.String)). — PM 77-1, Nov 27 '15 at 22:21

You need to cast the input as a integer also that's not the way you declare arrays. Try this:

String teamnum = Input.nextLine();
 int newnum = Integer.parseInt(teamnum);
 int[] teams = new int[newnum];

You can declare arrays by doing `int teams[] = ...`. I don't like it, but it works. – Paul Boddington Nov 27 '15 at 22:25
Yes I suppose that's true but it is not good practice as you said so I thought it'd be better. – Nov 27 '15 at 22:54
