                ex.printStackTrace();
            }
}              
}

What I have tried:

changed for loops , there is another way to write several for loops so that different array contents are printed as numbered

I just tested your code and it appears to work correctly. However, from your description I am guessing that you need to use array index values in a single for loop rather than foreach constructs.

You have a nested loop. So the inner code will be executed 4 * 4 = 16 times.

If you know for sure that both arrays have the same size and corresponding items at the same index just use one loop and print the items:

Java

for (int i = 0; i < word.length; i++)
{
    System.out.println(Satellite[i]);
    System.out.println(word[i]);
}

The above would print it out as requested in your question.

Solution 2

Java

for(int i = 0; i < 4; ++i)
{
//    String FILENAME = "F:\\"+ Ad +".html";
    System.out.println("Words:" + Satellite[i]);
    System.out.println("Word: " + word[i]);
}

Thancs, what about the code what it does is it takes user nput and then prints from Array Satellite and Word, so if user enters Android the arrays automatically add values

You need to use a List<t> or similar dynamic collection type, so you can add items to it as the program is running.
