Removing the 0 value from a sorted Array?

Question

I was wondering if there was a way to remove the default "0" value I get when I run the following code:

Scanner scan = new Scanner(System.in);

int [] x = new int[4];
for ( int i = 1; i < x.length; i++ )
{
    System.out.println( "Enter number " + i + ": ");
    x[i] = scan.nextInt();
}
Arrays.sort(x);
System.out.println(Arrays.toString(x));
}

The output is as follows

[0, i[1], i[2], i[3]]

Of course, all the array values here are actually the numbers entered into the console. The code is WORKING. It successfully sorts any numbers into the correct order, however, there is always this nasty 0.

I'm not looking to remove ALL 0's (I want the user to be able to enter 0 and have it show up) - -I just don't want the default 0. Any ideas?

Answer 1

Array indexes in Java are 0-based, not 1-based. So start iterating from 0 instead of from 1 and you should be good:

for ( int i = 0; i < x.length; i++ )

Answer 2

for ( int i = 0; i < x.length; i++ )
