Orhpaned case in switch statement

[Zoner]

Hey. This is my first post on this forum, and I'm just coming for a little help. I just started to teach myself Java yesterday, and i am having trouble writing a switch statement.

The error:

When I attempt to compile my program, I am told:
test.java:12 ';' expected
Switch(x)

test.java:14: orphaned case
case x>70

Regarding the first error, everything that I've read states that a ";" is not needed after a switch declaration. I'm not sure why the compiler would be calling for this.

I really have no idea what's up the the orphaned case error. Other threads and websites and suggested faulty bracket placement, but I have already checked and re-written every bracket. Any ideas.

Thank you.


[code]
public class test
{
public static void main(String args[])
{

System.out.println("\n Enter an integer");
Scanner s = new Scanner(System.in);
int x = s.nextInt();

Switch(x)
{

case x>70:
System.out.println("Exceeding speed limit");
break;
case 65<x<=70:
System.out.println("Getting close");
break;
case x==65:
System.out.println("Cruising");
break;
case x<65:
System.out.println("Slow");
}
}
}
[/CODE}

It's "switch", not "Switch". On top of that, you can't switch on a comparison
expression e.g. "x > 70".

kind regards,

That worked perfectly. Thanks for the help.

That worked perfectly. Thanks for the help.

I'm always slow I know but could you post what you finally got to work (in code tags)?

I'm always slow I know but could you post what you finally got to work (in code tags)?

Sorry, but i don't have the code anymore.

Essentially, I changed the uppercase "S" in Switch to a lower case one. Then, since boolean is not allowed in switches, I had to settle with an integer. I changed the values after "case" from, for example, x>70, to just 70.

Here is a very similar switch statement if this helps at all.

import java.io.*;
import java.util.*;
public class PlanetWeight
{    
    public static void main(String args[])
    {
    System.out.println("Choose a planet\n");
 
    System.out.println("1.  voltar");
    System.out.println("2.  Krypton");
    System.out.println("3.  Fertos");
    System.out.println("4.  Servontosn\n");
 
    Scanner a = new Scanner(System.in);
    int planet = a.nextInt();
 
    System.out.println("Enter your weight");
    Scanner s = new Scanner(System.in);
    int x = s.nextInt();
 
    switch(planet) 
    {
 
        case 1:
            System.out.println("Your weight on Voltar is " + (0.091 * x));
            break;
        case 2:
            System.out.println("Your weight on Voltar krypton is " + (0.720 * x));
            break;
        case 3:
            System.out.println("Your weight on fertob is " + (0.865 * x));
            break;
        case 4:
            System.out.println("Your weight on servontos is " + (4.612 * x));
    }
    }
}

Oh, I see you are no longer matching against ranges anymore.

anyone know what I'm doing wrong because it is telling me case 2 is an orphaned case
