Read integer array through white space with using limit in java -

my requirement is:

the first line of input consists of integer n (where n>=3) denotes size of array. in next line there n integers separated space correspond n elements in array. have used below code:

scanner length = new scanner(system.in);          system.out.println("please enter length of aarry:");          int n=length.nextint();          int[] numbers = new int[n];           scanner sc = new scanner(system.in);            system.out.println("enter elements seperated spaces: ");         string input = sc.nextline();         stringtokenizer strtoken = new stringtokenizer(input);         int count = strtoken.counttokens();         //reads in numbers array         system.out.println("count: " + n);         int[] arr = new int[n];          for(int x = 0;x < n;x++){             arr[x] = integer.parseint((string)strtoken.nextelement());             system.out.println("values are: " + arr[x]);          } 

but problem : above code read correctly integers entered white space specify limit entering values .please me how achieve this.

there several ways address 'issue':

• easiest: don't ask length of array => length = #tokens
• validate: if (n != count) system.err.println("invalid input...")
