POBubble-Sort with 2D Array
text
Body
copied!<p>Howdy, I do know how to implement a simple bubble-sort for 1dimensional array. But with 2dimensional or multidimensional, that's where I have my problems.</p> <p>So far I've been using this to sort 1Dimensional Arrays, works like a charm. But mostly with integer numbers, not strings:</p> <pre><code>boolean sort; do{ sort = true; for (int i = 0; i < testarray.length - 1; i++){ if(testarray[i] > testarray[i+1]){ temp = testarray[i]; testarray[i] = testarray[i+1]; testarray[i+1] = temp; sort = false; } } }while(!sort); // Descending Output // for (int k = testarray.length - 1; k >= 0 ; k--){ // Ascending Output for (int k = 0; k < testarray.length ; k++){ System.out.print(testarray[k] + ", "); } </code></pre> <p>Assuming I have:</p> <p>Customernumber, Name, Surname, Address</p> <pre><code>String customers[][] = {{"123", "John", "Doe", "Somewhere"}, {"007", "James", "Bond", "MI5"}, {"1337", "Lolcat", "Izgud", "Saturn"}} </code></pre> <p>Now, I want to choose to sort what to sort after: customernumber, name, surname or address. And after that I want to output it ascending or descending, depending what I want.</p> <p>I just have no idea how to implement this with bubble-sort. I want to stay in bubble-sort, , no other sorting algorithm, I want to learn how bubble-sort works in such a situation.</p> <p>For ascending and descending my idea would be: I could do an if-Loop. For example <code>if (asc == 1) then output ascending, else output descending</code>. The asc would then be asked via Console for example.</p> <p>Any help is much appreciated.</p>
