I use the BlueJ compiler to write and run Java programmes.
(I'm in school, n d board prescribes that
)
While writing a program, i experianced an unusual error, whenever I type ":", it turns into a label statement, and I cant use it for declaring cases in Switch...
Code:
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;
/**
* Write a description of class Designs here.
*
* @author (your name)
* @version (a version number or a date)
*/
public class Designs
{
public static void main(String[] args) throws IOException
{
boolean cont = true;
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
do
{
loop:cont = true;
System.out.println("/fWelcome to the Designs Class...");
System.out.println("01. Design 01");
System.out.print("Please Select an option : ");
try
{
int opt = Integer.parseInt(br.readLine());
}
catch(Exception oe)
{
System.out.println("Error in input :/n" + oe);
break;
}
Switch(opt);
{
case 1:
System.out.println();
default:
break loop;
}
} while(cont);
}
}
PS I have removed some parts of the code.
ERROR:
Code:
Designs.java:46: orphaned case
case 1:
^
Designs.java:48: orphaned default
default:

2 errors
Can someone please help?
THREAD CLOSED...
Sorry, I found my error:
I was referencing to variable opt, which was out of scope
Its limited to the try block...
':' turning into label statement
Linear Mode
