    <p>This isn't so much a programming question, but a clarification of the assignment.</p> <blockquote> <p>I don't know how to set the code up to read if the player wins or not as I don't have the scores.</p> </blockquote> <p>Well neither do any of us. We don't even know to which game you are referring, so we can't tell you how to find the score.</p> <blockquote> <p>Also I'm having issues getting Java to return two figures as one instead of 1+2 = 3 I need it to return 12. so return 1 + 2 doesn't work.</p> </blockquote> <p>That statement is unclear. What do you mean return two figures as one? Java methods can return either nothing (return type void), a primitive value or an object reference. If you want it to return 2 primitive values, like two integers, then you need to wrap it in an object which contains two integers.</p> <pre><code>class TwoInts { private int first; private int second; public TwoInts(int first, int second) { this.first = first; this.second = second; } public int getFirst() { return first; } public int getSecond() { return second; } } // in your other class class TestTwoInts { TwoInts getInts() { return new TwoInts(1, 2); } } </code></pre> <blockquote> <p>and lastly how do I get Java to print information from other methods?</p> </blockquote> <p><code>System.out.println</code> is accessible from anywhere in any Java program. It doesn't matter from which methods you call it.</p> <blockquote> <p>I have a question where I need to print a line that takes information from 2 other methods I've made.</p> </blockquote> <p>What is the question?</p>

    1. COHi Brandon my apologies for the question being unclear I have just awoken and trying to get through this, I believe the question is meant to be robust so whatever the int input is it will calculate the highest of two values? With the second question I meant for a return statement I need to return values in dollars and cents, ie input is int 3, int 5 it needs to return 350. so I need to know how to combined 3 with 5 then I can just multiply by 100..

    2. COEither express it in dollars using a float or express it in cents and multiple dollars by 100 to convert. For example, $3.50 could just be (3 * 100) + 50 = 350. Or use an object like the one I showed you, with an int for dollars and an int for cents. Though, honestly, for such a simple use case, that is over-engineering I think.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
