Help With Java Code Error

Java error code help?

Your while never ends because count is never changed.

I would have used a for loop instead but if you want to use a while then change it as follows:

while( count<=100 ) {
...total += count;
...count++;
}

Help with java code error!?

Does your Person class implement the Comparable interface? Collections.sort() expects a list of Comparable objects.

class Person implements Comparable
{
public int compareTo(Person p)
{
return this.toString().compareTo( p.toString());
}
}


If not, you would need to use a Comparator along with the overloaded version of the sort method that accepts a Comparable parameter.

class PersonComparator implements Comparator
{
public int compare(Person p1, Person p2)
{
return p1.toString().compareTo( p2.toString());
// or some other comparison
}
}


Then you could use:

Collections.sort(list, new PersonComparator());

One error in Java code Please help?

Hi everyone

I am writing this code that uses an input box that has three choices and I am having trouble parsing the value afterward :

import java.io.*;
import javax.swing.JOptionPane;

public class MyType
{
public static void main (String[] args)
{
// Declare and Construct Variables
String strChoice, strTryString, strTryInt, strTryDouble;
int choice, tryInt;
double tryDouble;
boolean done = false;

//loop while user does not click cancel button
while(!done)
{

try
{
String message = "What is My Type?" +
"\n\n1) String\n2) Integer\n3) double\n4) Quit the program\n\n";
choice = Integer.parseInt(strChoice);

switch(choice)
{
case 1:
JOptionPane.showMessageDialog(nu... "Correct, any input can be saved as a String");
break;

case 2:
JOptionPane.showMessageDialog(nu... "Correct");
tryInt = Integer.parseInt(strChoice);
break;

case 3:
JOptionPane.showMessageDialog(nu... "Correct");
tryDouble = Integer.parseInt(strChoice);
break;

case 4:
JOptionPane.showMessageDialog(nu... "Exit.");
done = true;
break;

default:
throw new NumberFormatException();
}
}
catch(NumberFormatException e)
{
JOptionPane.showMessageDialog(null... try again");
}
}
}
}

Thank You :-)

Im having error on my Dr Java code?

The relevant line is cut off...

This should fix it:
catch (java.util.InputMismatch* *Exception e)

remove "* *"
