InputMismatchException not found?

[BurnTard]

Why on earth does the catch statement return an error? It's pretty much cut and paste from a java schoolbook! What the program does isn't all that important, without the try/catch, the code compiles fine... But as soon as the catch is introduced, I get an error saying "cannot find symbol," on line 23, the catch line.

[CODE=java]
import java.util.Scann er;

public class O2a{

public static void main (String[] args){

Scanner scan = new Scanner(System. in);
while (true){

System.out.prin tln("\nPlease enter two integers ");
try{
int a=scan.nextInt( );
int b=scan.nextInt( );

// Solution:
System.out.prin tln("a + b = " + (a+b));
System.out.prin tln("a - b = " + (a-b));
System.out.prin tln("a * b = " + (a*b));
System.out.prin tln("a / b = " + (a/b));
System.out.prin tln("a % b = " + (a%b));
System.out.prin tln("(a / b) * b + a % b = " + (a+(a%b)));
}
catch (InputMismatchE xception exception){
System.out.prin tln("Are you trying to quit the program? (y/n) ");
String inAnswer=scan.n extLine();
if (inAnswer=="n") {
continue;
}
else if (inAnswer=="y") {
break;
}
}
finally{
continue;
}
}
}
}[/CODE]

You must import the exception

import java.util.InputMismatchException;

Also doing

if ( str == "a string here" ){  }

isn't the correct way of
comparing two strings. Look at the methods of the String class.

Hope i helped.

Yup, thanks a bunch! Now I just have to figure out how to do the stringcompariso n in java... Why can't java just work like the other languages? I've barely used it for a week, and I've found so many unnecessary quirks already it's driving me bonkers!

None of the languages work alike; otherwise there wouldn't be any need for a language that works just like other languages do.

kind regards,

simply put, "You cannot build a house from the roof downwards". Java is a very stable language, if only you start with the basics and cement a good foundation.

Try reading someting entitled, Introduction to Java

All the information you need on Strings and any other Java controls can be found in the Java API Documentation. This resource should get you pointed in the right direction....th ere are multiple articles on the Strings there. I recommend bookmarking the Java API Documentation and using it as your primary resource when developing in Java.
