 | So the assignment is to make a Rock Paper Scissors Spock Lizard Player that plays against another student's player without using any Random generation for 100000 trials. We are supposed to be able to detect the patterns/sequences in the other player by storing their past moves and looking for any …  |
| | The below method is for my database assignment, and we are supposed to check if the "username" the user adds is already in the database. Somehow "newRecord.username = sc.nextLine();" this line does not work, the second time through the do-while loop It seems like it just ignores the line or … |
| | The method below for bubble sort should work, it displays the unsorted array fine, but for the sorted array it only displays one of the numbers. It seems to have just skipped over the other elements in the array. Here is a sample output: [COLOR="Green"]How many random even integers would …  |
| | The program like the title says is supposed to return the largest integer value in an user-inputted integer array, using binary recursion. And in the case of an empty array, return Integer.MIN_VALUE. I am kind of stuck on the logic of this binary recursive algorithm. I know there is errors …  |
| | The below is the main method, the wrapper method, and the array search method for a step recursive method used for finding the index position of the searched string. I am encoutering this problem when whatever search I put in, I get the return value of -1. Why and how … |
| | The code for the Towers of Hanoi is here, the problem is what will the rest of the recursive calls be? [CODE] //provided in the main method that String Src="Src", Aux="Aux", Dst="Dst"; public static void solve (int diskNumber, String Src, String Aux, String Dst) { if (diskNumber ==0) return; else … |
| | The program is supposed to find all the combinations of the letters in "computer", the algorithm was given to me, but I don't have any idea of how it dos its work, all I get from this is a an infinite amount of "nullp" Here is the code: [CODE] public … |
| | The task is to use a recursive algorithm to determine the sum of two numbers n1 and n2. I just keep on returning to using the formula n1*n1 +n2*n2 The part which I have questions is I don't get how to do this in a recursive way. Thanks! |
| | I have a prime number method here which checks if the user input is a prime number, I've done some stuff to try to make it more efficient, but I am wondering if there is anything else that can be done, maybe even make the complexity class constant? Thanks. Below … |
| | For homework, we have to find the time complexity class of certain algorithms and explain why it has that certain complexity class. So, I have a couple of questions: - Why is the first running time always so much longer than the ones after? (setting up the application or something??) … |
| | To start web-designing and making templates, you don't really need to know what every code means as you will gradually learn that as you make more designs. When you start off, you can check out other people's free templates, you can modify them according to your own preferences and web-site …  |
| | If your system's fine, here are some simple things you can try to speed up your stuff: - check your Windows Task Manager and go click on processes and check if there are applications that don't need to be running taking up a lot of space - there are often … |
| | We have an assignment to write a program finding the nth Fibonacci number. On the web, there are some standard mathematical equations for this, but that would just defeat the purpose of this assignment if I use those formulas. I have my current code down here(with some sketchy back up … |
| | I have implemented a catch statement for both the InputMismatchException and the ArithmeticException, how come they are not working? Also, if the user enters "quit" for the numerator, the program should be able to exit. But my understanding is that as soon as the user enters something that is not … |
| | I am writing a program for class on catching exceptions. Everything compiles fine, but when I try to test my error trapping, this shows up. [COLOR="Red"]"How many integers would you like to enter? f Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: -1 This is not a correct integer, please try again. Before: … |
| | I tried using this code below[CODE]if (choice == 6) main (); //takes the user back to the main method to the Main Menu[/CODE] but it won't compile. error message: [QUOTE]No applicable overload for the method named "main" was found in type "movitetogo". Perhaps you wanted the overloaded version "void main(java.lang.String[]args)throws … |
| | Beginner in Java. I am trying to find the highest value and lowest value of an array. The highest value works perfectly fine, while the lowest value keeps on giving me 0, even though 0 is not part of the array. Below is the code. Thanks. [CODE] mxm = n … |
| | Hi, I'm new to Java. Bumped into an error when doing a program. The code below will basically explain everything. This error [CODE]java.lang.ArrayIndexOutOfBoundsException: 15 at randomintegers.main(randomintegers.java:43)[/CODE]keeps on showing up and the program will not execute further. If anyone can help me soon it would be great! Here is my program … |
