ok.. i have solved many problems by myself but wtf, more errors... i dont get this $hit... anyway this some code for a calculator program (in good tradition i called it Kalculator )


i recieve the following error at the //********* (near if/else's at result=)

**incompatible types- found int but expected java.lang.String**
how can i fix this? thanks in adcance, sincerly


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

public class Kalculator extends JFrame
{
public Kalculator()
{
super("Kalculator");
Container c= getContentPane();
c.setBackground (Color.white);
c.setLayout (new FlowLayout());
c.add (new JLabel ("Kal"));
}

public static void main (String []args)
{Kalculator window= new Kalculator();
String temp,result;
EasyReader Read= new EasyReader();
System.out.print ("Select your desired operation (1,2,3,4) -->");
temp= Read.readLine();
int menuChoice= Integer.parseInt(temp);
System.out.print ("Enter the first integer:");
temp= Read.readLine();
int num1= Integer.parseInt(temp);
System.out.print ("Enter second integer:");
temp= Read.readLine();
int num2= Integer.parseInt(temp);
if (menuChoice==1)
result=num1+num2; //here is my error
if (menuChoice==2)
result=num1-num2;
if (menuChoice==3)
result=num1*num2;
if (menuChoice==4)
result=num1/num2;
else
System.out.print ("Incorrect entry. Please try again with one of the following options:/n"+
"1 adds two numbers/n"+ "2 subtracts two numbers/n"+ "3 multiplies two numbers/n"+ "4 divides two numbers");
System.out.print ("The result is"+result);
window.setSize(900, 400);
window.show();
}

}

result=num1+num2; //here is my error

result is a string...and u are trying to put ints in it. do this:

result = Integer.parseInt(num1 + num2)


You need to put the code in code tags, and btw use jikes....it is the best compiler out there and will give you good error messages.

That will still give you an error. result is a string and you're still trying to put ints into it. You'd be better off to change result to type int. This way, when you call the following method:

result = num1+num2 // this won't give you an error,

and when you call:

System.out.println("Your result is: " + result);

result is changed into a String for you implicitly.

you mean

int result= num1+num2; //?

that doesnt work, says .class expected

I mean

int result = Integer.parseInt(num1 + num2); //that will work

Print the exact error you're getting. .class expected doesnt' sound like it has anything to do with the aforementioned code.

It tried it int result = Integer.parseInt(num1 + num2); still doesnt work.
the exact error message is " '.class' expected" then i can click on a ? for more info and that says " '.class' expected No more information"

I use BlueJ as a compiler, but im switching to something else soon. I also downloaded j2sdk1.4.2 from java.sun.com

I'm using the compiler from Sun. I've never heard of that error.

int result = Ingteger.parseInt(num1 + num2);

works fine on my computer.

BlueJ is not a compiler. It's a modelling tool for student.

ok thats it, i didnt want to (have to install), but ill have to, im whipin out the java forte

ok thanks for all the "help" guys anyway, i couldnt find the forte so i went back to the code and to fix this all i had to do was make result=0 when i first declared it...

wtf u know im a BIG NNEEEWWBBBBIEEEE and i come to this forum and find window-like answers (reinstall it, diff compiler)

be ashamed

switch to windows guys code is 2 much for u ppl, u need the double click feature
