A GUI program that allows user to enter their name and the program will convert it in number using array.
For example if i input "EUNISE" the output should be 521149195
Because the letter equivalent of
a = 1
b = 2
c = 3
d = 4
e = 5
f = 6
g = 7
h = 8
i = 9
j = 10
k = 11
l = 12
m = 13
n= 14
o = 15
p = 16
q = 17
r= 18
s = 19
t = 20
u = 21
v = 22
w = 23
x = 24
y = 25
z = 26
I am writing a code in which a user inputs data as a string and that data must be verified as a valid number. A valid number is anything from 0-100. Then all valid numbers are converted into double numbers.
I am having trouble in how to write the validation part of the code.
Is it suppose to be an if, else statement? And if so how is it suppose to be validated?
I do now have the problem where i have to insert the numbers 1 to 100 individually in order to allow the program to accept a grade as high as 100%.
Also as soon as i type in a negative number the system crashes and shows me a error as attached.
/* Averaging grades To use the Java Swing interface to calculate the average of up to 50 grades.Average is calculated once -1 is entered as a value. The grades are then sorted from lowest to highest and displayed in a content pane which also displays the average. */
import java.awt.*; import java.awt.event.*; import javax.swing .*; import javax.swing.text.*; public class Averages extends JFrame { //construct components JLabel sortPrompt = new JLabel("Sort By:");
Ok so I have my program working for the most part. In this program I am supposed to take input from the user until they enter a negative number and that works, the problem is that it doesn't work if I enter a negative number on the first prompt. For example if I enter a 100 it would prompt me again and if I enter a negative number it would quit and give me the average, but if I enter a negative number the first time I am prompted the program just gives me an error. How do I fix that?
import java.util.List; import java.util.ArrayList; import java.util.Scanner; public class Application { public static void main(String [] args){ Scanner input = new Scanner(System.in); List<Integer> grades;
Write a Java program that randomly generates a five-digit lottery number and prompts the user to enter a five-digit number. Each digit in the number is in the range between 0~9. The program should determine which prize the user wins according to the following rule:
• The user wins the first prize if the user input matches all five digits in the lottery number in exact order. • The user wins the second prize if the user input matches any four digits in the lottery number in exact positions. • The user wins the third prize if the user input matches any three digits in the lottery number in its exact position. • The user wins the fourth prize if the user input matches any two digits in the lottery number in its exact position. • The user wins the fifth prize if the user input matches any one digit in the lottery number in its exact position.
and here is my code. I cant get it to print the right statements.
import java.util.Scanner; import java.util.Random; class Hw5 { static int getPrize(int g1, int g2, int g3, int g4, int g5, int u1, int u2, int u3, int u4, int u5) { //code for determining the prize comparing (g1, g2, g3, g4, g5) to (u1, u2, u3, u4, u5) if (u1 == g1 && u2 == g2 && u3 == g3 && u4 == g4 && u5 == g5)
I have been struggling with this program for weeks. This program is supposed to take a user's inputted odd number and then print out all prime numbers lower than that number.
public class PrimeNumber { Scanner scan = new Scanner(System.in); int userNum; String neg;
Creating an array searcher wherein it all depends on the user input. On the first user input it would be the array to search from while the second input would be something to be searched for inside the loop?
Some of the numbers can be converted from int to string , other cant. My problem is in if (input.length() == 3) and if (input.length() == 4. Basically having problems printing the 3 digit and 4 digit
public static void main(String[] args) { System.out.print("Skriv: "); Scanner console = new Scanner(System.in); String input = console.nextLine(); int firstDigit = 0; int secondDigit = 0; int thirdDigit = 0; int lastDigit = 0;
I am new to java programming and using bluej for programming and i have tried this question what i have have given in title ... How to do the following question without using strings.
Write a java program to input a binary value and convert it into decimal and Vice Versa. Without using String. Please make it for blue j format.
I’m trying to write a program in Java that will take the input of a temperature in Fahrenheit and convert it to Celsius and Kelvin. This is what I have so far but when I run the program on Eclipse it says the temp. in Celsius is infinity and the same for kelvin. Why is it not preforming the operation and spiting out the correct numbers?
import java.util.Scanner; public class Temperature { public static void main(String[] args) { // This program converts temperatures from Fahrenheit to Celsius to Kelvin. double temperature1;// operands double temperature2; double temperature3;
Write a program that will provide temperature conversions between degrees Fahrenheit and degrees Celsius. Provide a method that will take an argument representing a temperature in Fahrenheit degrees and return the equivalent temperature in degrees Celsius. Also provide a method that will take an argument representing a temperature in degrees Celsius and return the equivalent temperature in degrees Fahrenheit. Conversion formulas are as follows: F = 9./5. * C + 32, C = 5./9. * ( F - 32 ), where F = Fahrenheit temperature and C = Celsius temperature. You must prompt for input using the Input class methods that are provided as a download for this unit.
I have two questions, 1st is why won't I get an output from my program when I run it? 2nd is how do I prompt for input using the Input class methods downloaded? The downloaded files are in .class form, and won't show any output when I run them.My code is:
import java.util.*; public class temp { public static void main ( String [] args ) { Scanner in = new Scanner(System.in);
I have a beginning Java Program I have been working on that creates a number guessing program where the computer guesses a number that the user is thinking of within a certain range. I so far have the program below, but need getting rid of a few kinks/ adding features.
-First, I need to set it up so that the user will be prompted and give a range. It should run and produce something like this:
Welcome to this first-ever mind-guessing program!
Please pick a range (higher than 1 and no larger than 50): 32
You will choose a number between 1 and 32... and I will try to guess it.
With each of my guess, you will tell me whether I am too high (h or H), too low (l or L), match (m or M), or you want to quit (q or Q). My objective is to find the number using as few guesses as possible.
-Second, the game is supposed to give up and restart after failing the five, guesses, but for some reason, after it fails the fifth time, it prompts a fifth guess once again instead, then restarts after- I need to prevent this, so that it should look something like this:
My fourth guess is 17: h My guess is too high?
My fifth guess is 16: h *** I am unlucky this round. I give up.
Let's play!
My first guess is 10: etc..
import java.util.*; import java.lang.Math; public class numguessprac1 { // Declaring variables public static String input; public static int quit; public static int guess; public static int wins;
trying to write a program that takes a user inputted number and converts it to a binary number.
Here's what I have:
package com.java2novice.algos; import java.util.Scanner; public class Converter { static Scanner console = new Scanner(System.in); public void printBinaryFormat(int number){ int binary = console.nextInt();
So I was going to try to create a program that prompts input and creates a file (That didn't exist before) with that input as name.Then, the program prompts inputs after stating questions such as 1 + 1, then if the user inputs an answer, put "Question # = Correct "or" Wrong.Code SO Far:
Java Code:
import java.io.BufferedReader; import java.io.File; import java.io.InputStreamReader; public class File_Read { public File_Read() {//File_Read is the Interactive object
[code]....
So that it puts the Correct or Wrong into the file.
I'm working on creating the Binary to Decimal program . hat is wrong with this part of my code. Why does it not take you into the loop.
import java.util.Scanner; public class question5 { public static void main(String[] args) { System.out.println("Enter a Binary number. "); // collect Scanner keyb = new Scanner(System.in); //
i am new to programming skills it may be silly question for experience but for me it's new thing. actually i tried a lot but i am facing problem when i trying to take input through Scanner. if i will take input a sentence directly as a string it's working . but when i am trying with Scanner the first word is showing next are not showing
public class Demo2 { public static void main(String[] args) { String s1="hi how are you"; s1=s1.replace('a', 'A'); s1 =s1.replace('e', 'E'); s1 =s1.replace('i', 'I');
[Code]...
this is working properly.
but when i trying with Scanner i am facing problem.
public class Demo2 { public static void main(String[] args) { java.util.Scanner scn= new java.util.Scanner(System.in) String s1=scn.next(); s1=s1.replace('a', 'A');
I am trying to write a program converting Fahrenheit to Celsius using a for loop. I get it to run and Fahrenheit goes to a hundred. My issue is that the Celsius just says 100 down the column and is not converting. I have tried messing with it, and can not figure what is wrong with it.
import java.util.Scanner; public class Controlstatement { public static void main(String[] args) { double F = 1.0; double Celcius = 100; System.out.printf("%s%20s", "Farenheit", "Celcius" ); for (int Farenheit = 0; Farenheit <= 100; Farenheit++) { F = Celcius * (Farenheit - 32 * 5.0/9.0); System.out.printf("%4d%,20.2f", Farenheit, Celcius); } } }
I am trying to make a translator program that will convert english to my custom binary. It works going from english to binary, but not going from binary to english.
import java.util.Scanner; public class Translator { public static void main ( String [] args ) { Scanner input = new Scanner( System.in ); System.out.print( "Would you like to convert English to Binary (yes or no)? " ); String answer = input.nextLine();
I just started programming yesterday, and I have been making little programs to learn some algorithms and the syntax of java. I tried making a program that could convert metric units into the American system. Whenever I try to compile the code, it shows up as an "incompatible type" error. I know this is probably a very obvious answer to most of you, but I can't figure it out.
import java.util.Scanner; public class MetricToAmerican { public static void main(String[] args) { Scanner scan = new Scanner(System.in); System.out.println("fWhat measurement would you like to convert into US system? celsius, meter, or kilogram ");
