Having problems in my while loop. I'm getting a
Exception in thread "main" java.util.NoSuchElementException: No line found.
at java.util.Scanner.nextLine(Scanner.java:1516)

Here's the code:

DecimalFormat money = new DecimalFormat("#,##0.00");// used to format money later on
date = JOptionPane.showInputDialog("Enter pay period ending date (mm/dd/yyyy): "); //hold user input into date

Here is the other code containing my paycheck class:
`public class Paycheck
{
//Declare variables
private final String EMPLOYEE_ID; // Employee ID
private final String EMPLOYEE_NAME; // Employee Name
private final double WAGE_RATE; // Wage Rate
private final double TAX_RATE; // Tax Rate
private final double HOURS_WORKED; // Hours Worked
private double grossPay; // Gross Pay
private double taxWithheld; // Tax Withheld
private double netPay; // Net Pay
// Constructor
Paycheck(String id, String name, double wage, double tax, double hours)
{
EMPLOYEE_ID = id;
EMPLOYEE_NAME = name;
WAGE_RATE = wage;
TAX_RATE = tax;
HOURS_WORKED = hours;
}
public void calcWages()//calculates wages
{
grossPay = HOURS_WORKED * WAGE_RATE;
taxWithheld = grossPay * TAX_RATE;
netPay = grossPay - taxWithheld;
}//end calcWages
public String getEmployeeID()//returns Employee's ID
{
return EMPLOYEE_ID;
}//end getEmployeeID
public String getEmployeeName()//returns Employee's name
{
return EMPLOYEE_NAME;
}//end getEmployeeName
public double getWageRate()//returns Employee's wage rate
{
return WAGE_RATE;
}//end getWageRate
public double getTaxRate()//returns Employee's tax rate
{
return TAX_RATE;
}//end getTaxRate
public double getHoursWorked()//returns Employee's hours worked
{
return HOURS_WORKED;
}//end getHoursWorked
public double getGrossPay()//returns Employee's gross pay
{
return grossPay;
}//end getGrossPay
public double getTaxWithheld()//returns Employee's tax withheld
{
return taxWithheld;
}//end getTaxWithheld
public double getNetPay()//returns Employee's net pay
{
return netPay;
}//end getNetPay
}`
Sorry for the lengthy code. I figured someone might need a good majority of the code to figure out what was going wrong. If there are better ways of doing things as far as using better methods, I am forced to stick to simplicity, so please try and work within the realms of this code. I am a beginner in Java btw.
Thanks!
