Error symbol not found Please help

[laurenceshan]

hi guys im new to java and having real troubles with a program that im trying code everytime i compile it i get symbol not found error?
maybe somebody can explain this to me.

the coding is below:






import javax.swing.*;
import it.*;
import java.awt.*;

public class RedBlue
{
public static void main(String [] args)
{
int points = 0;
int first = 0;
int secon = 0;

while(points>=0&&points<=50)
{
inputColour();
}
System.out.println
("Your score was "+points);
if(points>=50)
{
System.out.println
("You won");
}
else
{
System.out.println
("You lose");
}
}


static void inputColour()
{
int comp = (int)((Math.random()*2)+1);
int user = Integer.parseInt(JOptionpane.showInputDialog
("Enter 1 for Red or 2 for Blue"));
if(comp == user)
{
points = points+20;
}
else
{
points = points+20;
}

if(user==1)
{
red();
}
else
{
if(user==2)
{
blue();
}
else
{
JOptionPane.showMessageDialog(null,
"Enter 1 for Red or 2 for Blue");
}
}
}

static void red()
{
first = (int)((Math.random()*10)+1);
secon = (int)((Math.random()*10)+1);

ans = Integer.parseInt(JOptionPane.showInputDialog
(first+secon+", "+first+secon+secon+", "+first+
secon+secon+secon+"... what is the fourth term?"));

if(ans==(first+(secon*4)))
{
points = points+5;
JOptionPane.showMessageDialog(null,
"CORRECT, you now have "+points+" points");
}
else
{
points = points-5;
JOptionPane.showMessageDialog(null,
"INCORRECT, you now have "+points+" points");
}
}

static void blue()
{
first = (int)((Math.random()*10)+1);
secon = (int)((Math.random()*10)+1);

int oper = (Math.random()*3)+1;

if(oper==1)
{
int ans = Integer.parseInt(JOptionPane.showInputDialog
(first+" + "+second+" = ?"));
if(ans==(first+secon))
{
points = points+5;
JOptionPane.showMessageDialog(null,
"CORRECT, you now have "+points+" points");
}
else
{
points = points-5;
JOptionPane.showMessageDialog(null,
"INCORRECT, you now have "+points+" points");
}
}
else
{
if(oper==2)
{
ans = Integer.parseInt(JOptionPane.showInputDialog
(first+" - "+second+" = ?"));

if(ans==(first-secon))
{
points = points+5;
JOptionPane.showMessageDialog(null,
"CORRECT, you now have "+points+" points");
}
else
{
points = points-5;
JOptionPane.showMessageDialog(null,
"INCORRECT, you now have "+points+" points");
}
}
else
{
if(oper==3)
{
ans = Integer.parseInt(JOptionPane.showInputDialog
(first+" x "+second+" = ?"));
if(ans==(first*secon))
{
points = points+5;
JOptionPane.showMessageDialog(null,
"CORRECT, you now have "+points+" points");
}
else
{
points = points-5;
JOptionPane.showMessageDialog(null,
"INCORRECT, you now have "+points+" points");
}
}
}
}
}
}







now to the errors.. they are all symbol not found, therefore my thinking is that its one small error that i have repeated

When you have a ton of errors, then you know that the problem is more than that there's something wrong with your program, no, the problem here is that there's something wrong with *how* you're programming. If you are not using an IDE, you must compile your code frequently, in fact you should do this after every 1 to 2 lines of code that is added, and you should not add any new code until all compilation errors have been fixed. I suggest that you restart this project and first create a program skeleton -- nothing but the class name and perhaps an empty main method, make sure that it compiles and then add your code 1-2 lines at a time, compiling and repairing as you go. Also, take care to use correct spelling and capitalization (it's JOptionPane, not JOptionpane), take care to make sure that you don't use variables that are not visible where you're trying to use them, such as the points variable which is declared inside of the main method and is only visible inside of the main method.

Best of luck.
