Calc do while loop and phrasing gone wrong.. :(

[jcnanaman]

hello, just tinkered with some good ol Eclipse after a 1 year programming rest..
and i cant seem to find out what the F is wrong here...
"cannot be resolved" errors are everywhere..

HELP and advise would be very much appreciated..


HERE IS MY CODE:

MAIN CLASS

package methodsWithParam2;
import java.util.Scanner;

public class mainClass {

public static void main(String args[]){
do{
Scanner jc = new Scanner(System.in);
int x,y,ch;


subClassSum subClassSumObject = new subClassSum();
subClassDiff subClassDiffObject = new subClassDiff();
subClassMult subClassMultObject = new subClassMult();
subClassDiv subClassDivObject = new subClassDiv();
subClassMod subClassModObject = new subClassMod();

System.out.println("Enter 1st number: ");
x = jc.nextInt();
System.out.println("Enter 2nd number: ");
y = jc.nextInt();
int total = (x+y);
int difference = (x-y);
int product = (x*y);
int quotient = (x/y);
int modulo = (x&y);

System.out.println("Please choose operation");
System.out.println("1. Addition \n2. Subtraction\n3. Multiplication\n4. Division");
ch = jc.nextInt();

switch(ch){
case 1:
subClassSumObject.sum(total);
break;
case 2:
subClassDiffObject.diff(difference);
break;
case 3:
subClassMultObject.prod(product);
break;
case 4:
subClassDivObject.quo(quotient);
subClassModObject.myMod(modulo);
break;

default:
System.out.println("Invalid operation");
break;
}



System.out.println("More? [1=Y / 2=N]");

int z = jc.nextInt();
}
while(z == '1');
System.out.println("Thank you!");
}

}






SUM DIFF MULT DIV AND MODULUS METHODS



package methodsWithParam2;
import java.util.Scanner;

public class subClassSum {
public void sum(int total){

System.out.println("Dude sum of the two is: " + total);
}
}






package methodsWithParam2;
import java.util.Scanner;

public class subClassDiff {
public void diff(int difference){

System.out.println("Dude difference of the two is: " + difference);
}
}




package methodsWithParam2;
import java.util.Scanner;

public class subClassMult {
public void prod(int product){

System.out.println("Dude product of the two is: " + product);
}
}




package methodsWithParam2;
import java.util.Scanner;

public class subClassDiv {
public void quo(int quotient){

System.out.println("Dude quotient of the two is: " + quotient);
}
}




package methodsWithParam2;
import java.util.Scanner;

public class subClassMod {
public void myMod(int modulo){

System.out.println("remainder is " + modulo);
}
}








THANK YOU IN ADVANCE!

you should really sepparate your classes with the thingies, you got me really confused for a second.

BTW are you talking about the "SUM DIFF MULT DIV AND MODULUS METHODS" line (having the "cannot be resolved to a type" problems)?
I believe you wanted to make it a comment? :-?
oh, also you can't use a variable that you defined in a loop in another loop - int z;

[jcnanaman]

oh sorry bout the confusion sire..

the
SUM DIFF MULT DIV AND MODULUS METHODS
line in actually not included on the code itself..
i just posted the code of every separated methods.. those pieces of codes that follow are the ones being called..

i should have arranged them more clearly.. sorry bout that.. but anyways.. the latter part of your reply made sense bout int z being defined inside the loop..


thanks a ton sire!
