I'm trying to make a test on java. So far I'm on Question 1 and I'm having this issue. The if else statement won't allow me to add to the score.
class ExamEngine {
static CinReader Cin= new CinReader();
static int Score=0;
public static void main(String[] args) {
System.out.println("Type in your name.");
String name=Cin.readString();
[Code] ....
If I remove the "Score++;" bit, everything is fine. But I need to add to the score when they answer a question right. However, with "Score++;" there, I get this issue: 'else' without 'if'.
Note that this cannot be multiple choice, so that's why I'm using if-else, because I don't think a case system would work here.
Is there a way I can make this work while adding to the score?
I am using Eclipse programming for android. I have a game working fine but looking to add a little flare to it. Currently more scoring system just displays the current sore so if your score is 3,000 and you score 300 more it just changes to 3,300.
My question is how can I get the score to count from 3,000 to 3,300 really fast giving it the arcade feel of your score counting up? I tried timers with delays but it gets slowed down and buggy.
I am creating a program called "Mad Math Machine". This program is to generate random arithmetic questions, with integers ranging from -12 to 12, for the user to answer. The user has three lives. Once they get more than three questions wrong, they run out of lives, and their "score" (the number of questions they answered correctly) is taken.
I have the large chunk of the program (the arithmetic questions and answers) completed. The only part I am stuck on is the scoring system. I believe that arrays would be useful for this task, but I have little idea of where to start. Here is what the scoring list should be able to do:
- It should print out the top ten recent players and their scores. - A separate list should show the top-two highest scores of all time.
*I didn't think it was relevant, but I can include the program code. Up until this point, I have created methods to keep track of the score, but I have simply left them commented out so I could build the rest of the program.*
I was thinking to make a game where a button is appearing in random spots and you have to click it, and once you click it you're score goes up. But I don't know how to make the score appear in the JFrame, and I want the score to update everytime the Button is Clicked.
Here is the code:
Java Code:
package clickmegame; import java.awt.Dimension; import java.util.Random; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; public class ClickMeGame { public static void main(String[] args) {
So from what iv learnt in Java and programming in general is that using a case statement is far more efficient that using multiple IF statements. I have an multiple IF statements contained within a method of my program, and would like to instead use a case statement.
Alright, so i'm working on this and what I want to do is calculate all of the answers when the values of the correct answer = 1 and the incorrect answer = -1 so at the end of the test I can calculate answer + answer2 + answer3 and so on to get a total score...How do I do this? I've been looking online for 3 hours and i'm just stumped.
import java.util.Scanner; class HorticultureQuiz { public static void main(String[] args){ String name; String major; String confidence;
[Code] ....
I thought I could make each answer = to 1 but then I would need a -1 if the answer was incorrect so I tried this.
char answer = sc.nextLine().toLowerCase().charAt(0); if (answer == 't' || answer == 'T') answer = 1; { System.out.print("Great Job, that is correct!"); } else answer = -1; { System.out.print("Correct answer is false"); }
I've been working on this same assignment using netbeans. I've completed the exercise and when I run it, it works. However, netbeans still had errors listed in the left hand numerical column and it asks me if I still want to run the program with errors when I hit run?
package TestScores; import java.util.Scanner; // Name: Joe // Date: ........ // Desc: Test Score Averages
[code].....
I found this thread while doing a google search trying to find out the error in my code.
So I'm working on this game for a school project and I have 2 problems
1.I do not know how to display the players score in the panel 2.Every single time the console reads the second button I click on as a 0 instead of the number underlining it
import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.*; import javax.swing.border.*; public class Matchgame extends JPanel implements ActionListener { private final JPanel Brd = new JPanel(new BorderLayout(3, 3));
Most of my code is done for making this Jeopardy game, the only problem I seem to have is to have variables that retain values after going through a loop, in this case the variables counter and score in the method responsePrompt
After going through the 25 questions, the value counter remains at 1, and score is either 1 or -1, nothing more, nothing less. I've had the variables initialized at 1 both inside and outside of the for loop. Full code below just in case it's something outside the method
import java.util.*; import java.io.*; public class Project10 { public static void main(String[] args) throws java.io.IOException
I'm working on a homework assignment and I keep getting a compiler message this is the message
GradesAverage.java:44: error: variable totalgrade might not have been initialized System.out.println("Over all you have " + totalgrade); ^ 1 error
The homework is this Write a program that has variables to hold three test scores. The program should ask the user to enter three test scores and then assign the values entered to the variables. The program should display the average of the test stores and the letter grade that is assigned for the test score average. Use the grading scheme in the following table:
Test Score Average Letter Grade 90-100 A 80-89 B 70-79 C 60-69 D Below 60 F
This is my code
import javax.swing.JOptionPane; // Needed for JOptionPane class import java.util.Scanner; // Needed for the scanner class public class GradesAverage { public static void main (String[] args)
i am a french student in France and i am studying informatics . For validating my term at the beginning of January i have a projet in JAVA to do called YAHTZEE. It's a game which i have to code WITHOUT USING AN OBJECTS. I already started the coding, i did all the beginning stuff ( to call the number and the names of players, to roll the 5 dices, i made the code for all the scoring points too(rules) ) but i can't do the table score which updates the new scores after each turn ( 3 turns in total) .
I have a txtfile which I read and go through. My question is what are the ways I could do to read a txtfile of words and assign an empty score to each of the word in it. So each word will have a 0 value. Later on I will manipulate the score but for now I want each word to have a 0 score.What I have at the moment is reading a text file full of words eg:
private void readtextfile() { try { Scanner rd = new Scanner( new File("filename")); List<String> lines = new ArrayList<String>(); while (sc.hasNextLine()) { lines.add(sc.nextLine());
[code]...
how to make each of the words to have a score of zero 0?
Conditions : Need to print all the inputted data(name,score) and the average.
import java.util.Scanner; public class Case2 { public static void main(String[] args) { Scanner input = new Scanner(System.in); int[] score = new int[5]; String[] name = new String[5]; int ave = 0;
I'm getting constructor null pointer exception but i don't know what has gone wrong...
private int capacity; // maximum capacity of the board private double minimum; // minimum distance of the flyer private SortedLinkedList sortedList; private int size = 0; public ScoreBoard() { capacity = 10; minimum = 0.0; sortedList = new SortedLinkedList();
So I want to make a simple Java that ask the user to pick a powers and it has two options.If the user picks magic then execute the first if statement then ask the user again which type of magic the user wants.I can't make it work it keeps printing the else statement. Why is that?
import java.util.Scanner; public class Variable { static Scanner zcan = new Scanner(System.in); public static void main(String[] args)
I`m trying to make a gradebook that uses random number generator to give the score, I also need to implement student numbers and sort everything with a total at the bottom. But I cant figure out how the bubblesorting works. This is my code so far:
package karakterbok; import static java.lang.Math; import java.util.Random; public class Karakterbok { public static void main(String[] args) { Random karakterer = new Random(); Random studid = new Random ();
1.Write a JAVA program that will input 10 scores and output the Highest and Lowest score.
2.Write a JAVA program that will input the base and power and display the result: Example: Base is 4 Power is 2 the answer is 16 (Note: Math.pow( ) method is not allowed)
3.Write a JAVA program that will input an integer number, and then will output the sum of all inputted numbers. The program will stop in accepting inputs if the user entered 0.
I'm trying to run an if statement with an input condition and here is my code.
import java.util.Scanner; public class App10A { public static void main(String[] args) { Scanner fun = new Scanner(System.in); System.out.println("What's your name?"); String name = fun.nextLine();
[code]....
When the computer asked me "What's your name?", I typed in Victor, then the result turned out to be "Oops, try again!".I typed in Victor (without parenthesis) and "Victor" and both gave me the negative results.What exactly should I put in in order to get "This is the result I wanted!" ? how should I modify my code in order to get "This is the result I wanted!" when I put in Victor (without changing the equal sign)?
How do I use a variable in an if statement to return a public void method from another class? I've tried:
System.out.print("select 1 - 6: "); Scanner myScanner = new Scanner(System.in); myScanner.nextInt(); if (myScanner.nextInt()==1) { carSelection colour = new carSelection(); colour.carSelection();
The method colour in class car selection is just 4 print line statements? I've // out the if statement to see if it is correctly calling the method and displaying the data and it is?
I'm having a problem where an if statement isn't working. In the Person class boolean olderThan ignores my if statement so it always returns false and I just don't get why that's happening.
import java.util.Calendar; public class Person { private String name; private MyDate birthday; public Person(String name, int pp, int kk, int vv) { this.name = name;
In the program below I populated three arrays: student id, name, and GPA. The findStudent() method attempts to match users input with the input stored in the studentID array using an if/ else statement. When I use the if/ else statement the else always executes regardless if the IDs match? I am trying to get JOptionPane.showMessageDialog(null, "Incorrect entry"); to print only if the IDs don't match.
Java Code:
//FILE: StudentIDArray.java import javax.swing.*; //Used for the JOption dialog boxes import java.util.*; //Used for Scanner input public class StudentIDArray { boolean nameFound = true; final int numOfElements = 2; //Final int to control to loop for data
My program basically has 2 executeQuery statements. Based on the result of the first sql query the 2nd sql query gets executed (I intend to use if else ladder). The control executes the first query but never executes the second one.
I have this JAVA written but I can't get the parameters for the if statements right.
import java.util.Scanner; public class myFirstJAVA { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Please enter command: "); String text = input.nextLine();
