    Hi,

    You have to apply for-loop statement, if want to print arrays value(5 values..) which you have decalared in private static void printarr(int[] arr). See this :

    private static void printarr(int[] arr) {
    for(int i=0;i<arr.length;i++)
    {
    System.out.println(" "+arr[i]);
    }
    }


    then, in the main method, you have to put array variable in printarr(int[] arr) method. See this :

    public static void main(string args[]) {
    int[] arr = new int[5];
    printarr(arr);
    }
