    Default Searching an array for a certain value reporting back index position

    I have not experimented with binary searches and things like that so my code is using a simpler way. The value I'm searching for is 9 which is found at index position 4 but my program is reporting that the value is found at index position 9. There is something I'm doing wrong here:

    public class SearchArrayForValue
    {
    	public static void main(String args[])
    	{
    		int numbers[] = {2, 5, 7, 8, 9, 11};
    		int value = 9;
    		int i;
    		int j;
     
    		System.out.print("The values in the array are: ");
     
    		for(i = 0; i < 6; i++)
    			System.out.print(numbers[i] + " ");
     
    		for(j = 0; j < 6; j++)
     
    			if(numbers[j] == value)
    				break;
     
    		System.out.println("\nValue of " + value + " found at index position " + numbers[j]);	
    	}
    }

    numbers[j] is the value in the array at index j


    Note: The code should use {}s to enclose the statements inside of loops and if statements.
    If you don't understand my answer, don't ignore it, ask a question.

    I experimented and discovered I only need to use the loop control variable in this case j to output the index position.
