    Cool question about printing arrays

    For my java assignment this time, I want to know how to print an array value in a string. Here's the problem:

    Instructions:

    After the following code is executed, what are the values of p[ 3 ], q[ 3 ], and r[ 3 ]? Explain. (As you work toward formulating your answer, you might want to add a System.out.println method to the program in the box provided.)


     
        String[] p = { "A", "B", "C", "D", "E" }; 
     
        String[] q = { p[ 0 ], p[ 1 ], p[ 2 ], p[ 3 ], p[ 4 ] }; 
     
        String[] r = p; 
     
        p[ 3 ] = "Z";

    That's the code they give me. What do I add to that to print the right thing? All responses appreciated.

    Sincerely, ghostheadx

    Default Re: question about printing arrays

    The point of this assignment is to get you to understand the indexing system used for arrays. This tutorial explains the topic well.

    On to your question, search System.out.println to see how it is used.
    What were you told to print? ...read the instructions again.
    Note that printing is not required, it is like a verification system to show the actual answer so you can compare to your answer; like when you use subtraction to verify addition.
