[mfshake]

I am try to make the user enter 10 names and then display them out in
reverse order. I am having trouble with my for statement. can someone help me. Thanks

                 Scanner reader = new Scanner (System.in);
        String [] names = new String [10];
        int count = 0;
        while(count < names.length){
            System.out.print("Enter your name: ");
            String name = reader.nextLine();
            names[count] = name;
            count++;
        }
        System.out.print("\nHere are the names:");
        for(int i = 0; i < count; i++){
            System.out.print("\n" + names[i] + "\n");        
               }

the problem is with your for loop..instead start from 0, start from 9. the string is stored in array.

[code=java] Scanner reader = new Scanner (System.in);
String [] names = new String [10];

Also new String [10]; would give you 11 names not 10

That's wrong. maybe you are thinking of VB, but that will create an array of length 10, with indices [0] up to and including [9].

It's hard to comment on code we can't see (hint).

Remember a loop terminates when its test condition is false.

Remember a loop terminates when its test condition is false.

The best solution would be to look at each line of code and check the value of each variable and BigDaddy's hint!

Better go through your loop "manually" writing down the values of i and count at each pass. That way you can be able to see what is going on (or what is not going on).
