Skipping While Loop After First Run

Dec 11, 2014

I need to add a kb.nextLine(); somewhere but I've tried adding it after nextInts and it hasn't worked. The problem is in the test.

public class Account{

//instance variables
private static double annualInterestRate;//this is the class variable
private int id;
private double balance;
private java.util.Date dateCreated; //creates an object from the date class in java

[code]....

Skipping Else If Statement

Jun 5, 2014

I have two different Class object arrays storing 3 elements (2 Store arrays, both initialised to hold 3 Product objects). The problem is, I can set data to one array with no problem but my program doesn't want to set the data for my second array.

For instance, The main problem is this method:

public void addData(String store, String newName, int newDemand, double newSetup, double newUnit, double newInventory, double newPrice)
//Method that sets the data value for a product
{
if (store.equalsIgnoreCase("callaghan"))//!!!!Goes from this line in the debugger
if (noOfProductsCallaghan==0)
{
setData(product[0], newName, newDemand, newSetup, newUnit, newInventory, newPrice);
noOfProductsCallaghan++;
}
else if (noOfProductsCallaghan==1)

Skipping Further Prompts When Certain Conditions Are Met

May 1, 2014

Is there any way to skip the 2nd and 3rd questions in this instance if I input "exit" or make an error in the 1st input. Essentially skip over the "enter 1st number / enter second number" prompts and go straight to the switch statement? In the case of "exit" exit the program immediately without the prompts. If an error, loop around to the beginning without the further prompts.

import java.util.Scanenr;
public class Meddle {
public static void main (String args []) {
double n1,n2,answer;
Boolean check = true;

Skipping Lines During Debugging

Dec 19, 2008

I'm working or better say.. I'm trying to work :) with Maven projects (m2eclipse plug-in) and Eclipse IDE. The problem I have is that sometimes the debugger seems to skip some lines of the code without a reason.

Is there an issue of synchronisation with my .class files?

Program Skipping Over User Input

May 19, 2014

So i'm just toying around with making a simple inventory system, and when i'm trying to get the user's input (first the ID number, then the item name, then the item price) it will take the ID number, output asking for the name (but not take any input for it) and then ask for the item's price. I'm really not sure why it's never happened to me before when getting user input.

This is the input part of my code:

public void getInfoAdd() {
int id;
String name;
double price;
System.out.print("Enter ID: ");
id = sc.nextInt();
System.out.print("Enter item name:");
name = sc.nextLine();
System.out.print("Enter desired price: ");
price = sc.nextInt();
addItem(id, name, price);
}

And this is what it outputs:

Quote
Enter ID: 2
Enter item name:Enter desired price: 40
Successfully added: 2 $40.0

Unable To Print A Loop Inside Array Of Greater Size Than Loop Itself

Jan 27, 2015

I am trying to print a loop inside an array of a greater size than the loop itself. Like for example I have an array of size 7 but it has only 3 elements.

int[] array=new int[7]
array[0]=2;
array[1]=3;
array[2]=4;

now what I want to do is print these three numbers in a loop so that my array[3]=2;array[4]=3;array[5]=4 ...... till the last one. Also the array could be any size and not just 7.

While Loop Inside A For Loop To Determine Proper Length Of Variable

Feb 25, 2014

Here's the code: it's while loop inside a for loop to determine the proper length of a variable:

for (int i = 0; i < num; i++) {
horse[i]=new thoroughbred();
boolean propernamelength = false;
while (propernamelength==false){
String name = entry.getUserInput("Enter the name of horse "

[code]....

I was just wondering what was going on here -- I've initialized the variable, so why do I get this message? (actually the carat was under the variable name inside the parentheses.

When Type Quit To Close Outer Loop / It Still Runs Inner Loop

Nov 2, 2014

I have everything else working. My problem is that when i type "quit" to close the outer loop. It still runs the inner loop. The National Bank manager wants you to code a program that reads each clients charges to their Credit Card account and outputs the average charge per client and the overall average for the total number of clients in the Bank.

Hint: The OUTER LOOP in your program should allow the user the name of the client and end the program when the name entered is QUIT.In addition to the outer loop, you need AN INNER LOOP that will allow the user to input the clients charge to his/her account by entering one charge at a time and end inputting the charges whenever she/he enters -1 for a value. This INNER LOOP will performed the Add for all the charges entered for a client and count the number of charges entered.

After INNER LOOP ends, the program calculates an average for this student. The average is calculated by dividing the Total into the number of charges entered. The program prints the average charge for that client, adds the Total to a GrandTotal, assigns zero to the Total and counter variables before it loops back to get the grade for another client.Use DecimalFormat or NumberFormat to format the numeric output to dollar amounts.

The output of the program should something like this:

John Smith average $850.00
Maria Gonzalez average $90.67
Terry Lucas average $959.00
Mickey Mouse course average $6,050.89
National Bank client average $1,987.67

Code:

public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
String name = "";
int charge = 0;
int count = -1;
int total = 1;
int grandtotal = 0;
int average = 0;

How To Store Value From Loop To Add To New Value From Loop

Feb 9, 2015

I am trying to make a program add values from a loop. So what its supposed to do is search through tokens on an imported file. The file lists State, Capital, and then capital population. Then take the population string, turn it into numbers, and then do stuff with the numbers. First I'm supposed to find the Highest and lowest population of the places in the file (which I did without problem), but the finally thing is I'm supposed to add each found population to the last so I can find the average of the populations.

I just cannot seem to grasp how to do that. I THINK I'm supposed to some how store the given value into a variable, but how do I get that variable to add to the new value?

like...?
Get token -> a
b = a
c = a + b

or wait no.....

Java Code :

import java.io.*;
import java.util.Scanner;
public class CapPopS
{
public static void main(String[] args) throws IOException
{
File stateCAP = new File("state-capital-2004population.txt");
if (!stateCAP.exists())

How To Add Within Loop

Feb 9, 2015

My teacher wants me to make a program that counts the amount of steps a student takes a day. The program asks for other info such as name, age, college. However I need to write a loop that will allow the user to enter how many ever steps they took and convert them to miles.how exactly to make the steps entered by the user within the loop be their own individual days like monday tuesday etc. Like the loop will ask how many steps did you take monday.. tuesday.. etc for each time it runs.

package StudentInfo;
import java.util.Scanner;

public static void main (String [] args){
Scanner scan = new Scanner(System.in);

Why Won't FOR Loop End

Feb 18, 2014

This is the first time I've ever gotten an infinite loop with a FOR loop. This program is supposed to let you enter five integer numbers and draw a bar chart based on those numbers. After the fifth number is entered, guess what? It wraps back around to zero again and starts over! Why the bleep doesn't it stop? The code is below:

Java Code: import java.awt.Graphics;
import javax.swing.JPanel;
import java.util.Scanner;

Loop To Add Integers From 1 To 50?

Mar 11, 2014

Create a loop where you add the integers from 1 to 50.

public class Sum50 {
public static void main(String[] args) {
int sum = 0;
int max = 50;
for(int i = 0;i <= max; i++){
sum=sum+i;
}
System.out.println("Sum is " + sum);
}

Semicolon After For Loop Is Not Necessary

Jun 15, 2014

I'm fairly new to programming, just started yesterday with a book I downloaded of the net. The book comes with a couple of examples on how to code and they all seem to work fine except for this loop.

class fordemo {
public static void main(String args[] ) {
int count;
for(count = 0; count < 5; count = count+1);
System.out.println(" This is count: " + count);
System.out.println("Your are all done! ");
}
}

I can't seem to find the problem. All it gives me is,
"This is count: 5
You are all done!"

When it's supposed to give me,

"This is count: 1
This is count: 2
This is count: 3
This is count: 4
You are all done!"

Found the error, semicolon after the for loop is not necessary. Should be...

class fordemo {
public static void main(String args[] ) {
int count;
for(count = 0; count < 5; count = count+1)
System.out.println(" This is count: " + count);
System.out.println("Your are all done! ");
}
}

How would I get rid of the redundancy of the dots1 and roof for loop in the nested for loop? The lines are just repeated and I'm not sure how to get rid of the redundancy.

Nested Do While Loop

just trying to learn it on my spare time and I'm doing do-while loops

throws java.io.IOException {
char choice, ignore;
do{
System.out.println ("Choose one:");
System.out.println("1. if");
System.out.println("2.switch");
 
[code]....

It makes no difference in the program wither i delete this block or keep it..how while (choice < '1'| choice >'2'); translates? I would assume it would be while (choice >= '1'| choice =<'2');?
