arrays - Java Fibonacci series -


what next step in order ask user of numbers in series of 30 wants see , prompts integer input - number between 1 , 30 (inclusive)?

so if user wants see fifth (5th) number of fibonacci series user input integer 5 in response prompt.

public class myfibonacci {     public static void main(string a[]) {          int febcount = 30;          int[] feb = new int[febcount];          feb[0] = 0;          feb[1] = 1;          for(int i=2; < febcount; i++) {              feb[i] = feb[i-1] + feb[i-2];          }           for(int i=0; i< febcount; i++) {                  system.out.print(feb[i] + " ");          }     } }

use scanner, or inputstreamreader read input console. scanner used in way:

scanner scanner = new scanner(system.in); if(scanner.hasnextint())     int someint = scanner.nextint();

another option use reader this:

bufferedreader br = new bufferedreader(new inputstreamreader(system.in));

and parse required data output of reader. using scanner simpler in cases though.
