    Default Pls check my code

    Im new to java. Im from the philippines. Please check my code.
    My goal is to accept 10 numbers using array then print only the even numbers afterwards.



    <package javaapplication1;
    import java.util.Scanner;
    public class JavaApplication1 {


    public static void main(String[] args) {
    Scanner od = new Scanner (System.in);
    /* variables */
    int nums [] = new int [10];
    int snum []= new int [10];
    /* code */

    System.out.println("Input 10 Real Numbers and I");
    System.out.println("will display the Even numbers entered");

    for(int i = 0; i <=10; i++){
    nums[i]= od.nextInt();

    if(nums[i]%2==0)
    {
    snum[i] = nums[i];
    }
    nums[i]= i+1;

    }

    for (int x = 0; x < snum.length; ++x)
    System.out.println(snum[x]);



    }




    }

    Can you explain what the problem is?
    Do you get errors? Copy the full text of the error messages and paste it here.
    Does the program give wrong results when executed? Copy the full contents of the console and paste it here and add comments saying what is wrong with the output.

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    There were no errors. I just cant get the right output.
    The output should look like this:

    Enter 10 numbers...
    1
    2
    3
    4
    5
    6
    7
    8
    9
    10

    The even numbers are:
    2
    4
    6
    8
    10

    It should look like that.. :screwy:

    I have wrapped the code already
    Where? Did you preview the post before (or after) saving it?
    The code should look like this:
       //------------------------------------------------------------
       //  Reverse a section of a String between b and e
       static String reverse(String s, int b, int e) {
          String res = "";
          for(; e >= b; e--) {    //  start at end and move to left
             res += s.charAt(e);
          }
          return res;
       }

    The < and > are not code tags. The code tags are: [code] and [/code]

    --- Update ---

    Copy the full contents of the console and paste it here and add comments saying what is wrong with the output.
    If you don't understand my answer, don't ignore it, ask a question.

    Can you do a preview BEFORE saving any updates?

    Add this before the code:
    [code]

    then add this after the code:
    [/code]
    See post#6 for how it should look.

    Does the program give wrong results when executed? Copy the full contents of the console from when the program is executed and paste it here and add comments saying what is wrong with the output.

    The beginning code tag is wrong. Take out the /
    The ending tag looks ok.

    you create array with fixed length. So the output print with zeros..

    you refer this link: Java array declaration without hard coding the size - Stack Overflow
