Illegal character \92 error.Tried everything

Question

Hi, Im trying to make a calculator program and in the line where I divide a by b, im getting an Illegal Character:\92 error for some reason. To type \ im using \\ as an escape character, and it seems to work earlier in the program with no problem.
Heres the code:
import java.io.*;
public class PA83 //Simple calc
    public void calculator()
        try
            InputStreamReader isr = new InputStreamReader(System.in);
            BufferedReader br = new BufferedReader(isr);
            System.out.println("Enter number 1");
            double a = ((double) br.readLine());
            System.out.println("Enter number 2");
            double b = ((double) br.readLine());
            System.out.println("1.Add\n2.Subtract a-b\n3.Subtract b-a\n4.Multiply\n5.Divide a\\b\n6.Divide b\\a\n7.Quit");
            int c = Integer.parseInt(br.readLine());
            switch(c)
                case 1:System.out.println(a+"+"+b+" = "+(a+b));
                break;
                case 2:System.out.println(a+"-"+b+" = "+(a-b));
                break;
                case 3:System.out.println(b+"-"+a+" = "+(b-a));
                break;
                case 4:System.out.println(a+"x"+b+" = "+(a*b));
                break;
                case 5:System.out.println(a+"\\"+b+" = "+(a\b));
                break;
                case 6:System.out.println(b+"\\"+a+" = "+(b\a));
                break;
                case 7:break;
                case default:System.out.println("Invalid Option. Please select a number from 1-6");
                break;
        catch(Exception e)
            System.out.println("Error: "+e.getMessage());
}              It highlights case 5 and gives me an illegal character:\92 error, but ive used the double slashes(\\) earlier in the println to choose an option without any problem there.
I dont understand why this is happening! Even if i remove the "\\" i get the same error , and as BlueJ suggested, i tried typing the line again to avoid some invisible character causing problems..

Hi,
I think we use "/" for division and not "\" .
thanks & regards,
