Write a java program that will ask a user to input grades until the user inputs the sentinel value -1. The program should test each input to determine whether 0<=grade<=100. If the grade entered is within this range, the program should print "Grade accepted;" if not, the program should print "Invalid input".

Increasing Counter When User Inputs C / D Or E

Feb 15, 2015

We are writing our own classes and methods. My instructor has provide the code

/*-------------------------------------------------------------------------
import java.util.*;
public class Assignment5 {
public static void main (String[] args) {

[Code].....

I am having trouble with the question counter. I need the counter to increase when c, d or e are entered. I think I need to set up a if or while loop but I'm not sure how to setup the variables. This is what I have for the counter so far.

[public int getNumberOfQuestions(){
numQuestions = 0;
numQuestions ++;
return numQuestions;

Storing Multiple User Inputs In Array

Feb 28, 2015

I need to generate a league table in Java based on results provided in the shape of user input. I have the 6 teams in an array. I need to ask the user how many wins, draws, losses each team has had.

for (String element : teams) {
System.out.println(
"Please enter the number of wins, draws and losses for " + element);
int[] wins = new int [6];
int[] draws = new int [6];
int[] losses = new int [6];
}

How do I pull 3 separate values from the user and then store each value in a separate element of each array? so if one team wins 3, draws 2 and loses 1 - I need to put 3 into the wins array, 2 into the draws array and 1 into the losses array? I then need to total all this in a table.

Return A String That Holds User Inputs

Apr 18, 2015

I'm working on an assignment for my Java Programming class that requires me to work with Multiple Classes.

Overview of the assignment: Create a "Database" that allows a user to input information about a College Class.

My program has three Classes:

The information that must be tracked in the Course Class is:
- Section Number
- Instructor
- Classroom
- Students (an ArrayList of class Student)

The information that must be tracked in the Student Class is:
- Name
- Major
- GPA
- Hours

The Driver class will use the main method to print the user a prompt asking for inputs, then display all of the user's inputs after he/she wished to exit the program.

I'm having no trouble with asking the user for inputs and then checking the validations for the inputs, I'm currently struggling with return a String that houses all of the user's inputs for the variables above. The information must be returned in a method called toString(). Both the Student and Course Class must have a toString() method that returns the information in the class (value of the variables), I must then call upon these methods from the main method of the Driver Class to print them back to the user.

The toString methods within the Student & Course Classes are at the bottom of the code

To Summarize: What I need to do within the toString() methods to return the values the user has inputted for the various variables? Such as.. Should I pass something through the method? Do I need the this keyboard to pass through the variable again? I just fear that I'm currently misunderstanding a very critical part of programming.

My Driver Class

import java.util.Scanner;
public class Driver {
Course courseInputs = new Course();
Student studentInputs = new Student();
public static void main(String[] args) {

[Code] .....

Need To Count Strings That How Many Inputs From User Were Numbers

Jan 30, 2014

import java.util.Scanner;
public class CountStringNumbers { // show the number of Strings that were numbers . . ..
public static void main(String []args){
int count = 0;
int countNumbers=0;
Scanner input=new Scanner(System.in);

[code]...

can count the numbers from 0-9 if the user puted but if it is 10 it doesnt count it , and i need to write all the numbers to have that option. . . . Is there an easy way that includes all the numbers? like if(word.equals(number)){<<<???? (numbers) i know htat doesnt work but is there anything similar ?? ??

countNumbers++;
}
System.out.println("Type Something , , , and to end the the termination type STOP");
word=input.nextLine();
count++;
}
System.out.println("You wrote "+count+" lines wich from those lines "+countNumbers+" were numbers and the programe terminated ");
}

Write A Program Where User Inputs A Month Between 1-12

Sep 21, 2014

I have an assignment where I'm supposed to write a program where the user inputs a month between 1-12 and then the right amount number in every month. I've tweaked the code a bunch of times, but I keep getting this error message:

insert "}" to complete StatementKALENDER_3.java
insert "}" to complete BlockKALENDER_3.java

The code:

import java.util.*;
import java.util.Scanner;
public class KALENDER_3
}
public static void main(String[] args){
Scanner scanner = new Scanner (System.in);
System.out.print("Skriv ett manadsnummer: ");

[code].....

I think I have just forgot to put in a few { } symbols, maybe an open loop?

Equivalent Arrays - Comparing 2 User Inputs To Determine If Same

Mar 4, 2015

I have been stuck on this for the past 2 hours, basically we have to compare user input, put user input into an array and compare for equivalency. An example of the program:

Array 1: 1 2 3 4 5 6 7 8
Array 2: 1 2 3 4 5 6 7 8
Array 3: 1 2 3 4 5 6 7 8 9
Array 4: 1 2 3 4 5 6 7 8

Array 1 & 2 are equal
Array 1 & 3 are not equal
Array 1 & 4 are not equal.

This cannot be done by importing Java.util.Array at all!! (my research only find this to compare arrays ) which is why I am having trouble starting off. My code thus far:

import java.util.Scanner;
public class Lab07b {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Enter Integer 1:");
int a = input.nextInt();

Swing/AWT/SWT :: Taking Inputs Based On Previous User Input

Jun 7, 2014

I'm developing a Swing application for the first time. To test my application, I have currently hardcoded some text labels and fields in a JPanel, so that a user can enter input details for a maximum of 3 segments. But this limits the maximum number of segments to 3. However, the requirement is that when the user enters the number of segments (could be greater than 3 as well), corresponding number of input sets need to be taken.

Screenshot attached, with values entered.

Basically I want to know how I should go about taking the inputs from the user.

User Inputs His Full Name In A String From Keyboard / Program Will Give His Initials As Output

Jan 5, 2014

Following is the code for my assignment where a user inputs his full name in a string from keyboard. It should be done using BufferedReader. The program will give his initials as output.

############################

For example: User inputs-> Ram Kumar Das

Program Returns-> R.K.D.

I am written the following piece of code. It does not return the correct output. If "Ram Kumar Das" is given as input, it gives R.K.K. as output. Arrays and objects are strictly not allowed.

Java Code:

import java.io.*;
public class Assignment
{
static int i=0;
static BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
public static void main (String args[]) throws IOException

Anomaly While Using Scanner Class For Taking Inputs

Feb 1, 2015

There is a problem that I am facing while using the Scanner class for taking inputs from the user. Suppose if I need to take an integer and a String input from the user, and I take the integer input first then the place where the user has to input the String skips and the variable shows a "" nothing on printing it. Suppose in this code snippet

import java.util.Scanner;
public class Test
{
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("Enter a number");
int n = sc.nextInt();
System.out.println("Enter a word");
String str = sc.nextLine();
System.out.println("Enter integer is " + n);
System.out.println("Entered statement is " + str);
}
}

The output is
Enter a number
13
Enter a word
Enter integer is 13
Entered statement is

I need to know why this happens and how should I avoid it. I've seen that taking the String input first solves the issue but while taking the input in a loop to populate a database the program only lets the user enter the first statement and the following statements are skipped.

I have made a simple form, it consists of 3 text box's textbox1, textbox2 and textbox3 as well as 1 button button1. What I want to be able to do is put numbers into textbox 1 and 2 and then show the multiplication of these numbers in textbox 3 when the button is pressed and I was wondering what is the standard way of reading these numbers from the text box and allowing us to do the conversion obviously in the textbox its a string and we need to convert to an int or double or whatever to be able to perform calculations on them then convert it back into a string to display in text box 3?

Sudoku Is Not Working For Few Inputs

Apr 22, 2015

The thing my coding for sudoku is not working for few inputs... it works fine with all its value initially at 0, but when i place numbers more than 4 at random places it stops responding (it doesn't show any value). My assignment is to get a solved sudoku for these values:

//Sample Input:
{0,2,7,3,8,0,0,1,0},
{0,1,0,0,0,6,7,3,5},
{0,0,0,0,0,0,0,2,9},
{3,0,5,6,9,2,0,8,0},
{0,0,0,0,0,0,0,0,0},
{0,6,0,1,7,4,5,0,3},
{6,4,0,0,0,0,0,0,0},
{9,5,1,8,0,0,0,7,0},
{0,8,0,0,6,5,3,4,0}

My current code

public class Sudoku {
static int userGrid[][]=new int[][]
{{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0},

{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0}};//[horizontal][vertical]

Exceptions For Multiple Inputs

Oct 29, 2014

I'm writing a program that accepts three doubles from the user, and performs calculations on them. I want to be able to handle input mismatch exceptions on each individually (i.e., if the user enters a double for the first, then a letter for the second, I'd like to be able to keep the value entered for the first, and only require that the user try again with the second, then the third, etc.)... I tried putting each input instance into its own try/catch blocks, but it always goes back to #1 when an invalid input is entered. Right now, I have all three in one try/catch:

Java Code:

package com.itse2317;
import java.util.Scanner;
import java.util.InputMismatchException;
class Triangle
{
public static double side1 = 0.0, side2 = 0.0, side3 = 0.0;

Reading Inputs Using Buffered Reader

Oct 13, 2014

I am trying to read the following input (which will be inputted by the user when run) using the BufferedReader approach:

1
*** * * * *** *** *** ***
* * * * * * * * *
* * * *** *** *** *** ***
* * * * * * * * *
*** * * *** *** *** ***

I am reading each line of the input one line at a time and incrementally storing four char positions into an array, so i am able to hold a vertical representation of each column. I.e. column 1 will be stored in array[0].

The problem with my code is that is does not read the last line of the input, it reads all the other inputs before it but just refuses to read the last line and execute the procedure of storing the characters.

Code:

public void defuseBomb(){
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
System.in));
String asciiLine = reader.readLine()+ " ";
int digit = (asciiLine.length())/4;
