int value of shift?

[Dillinger4]

Does anyone know what the integer value of shift is?

 char keytyped = ke.getKeyChar();
 if(Character.getNumericValue(keytyped) == ???){
     //...........
  }

Isn't there a VK_* list somewhere in the SDK docs?

Im using an old C++ book to look up the ASCII character encodings. For some reason

System.out.println(Character.getNumericValue(keytyped));

was printing -1 when the Backspace key was pressed but by casting the char to an int a numeric value of eight is printed.

char keytyped = ke.getKeyChar(); 
int i = keytyped; 
System.out.println(i);

Character.getNumericValue returns -1 for every character except '0' through '9' and other numeric signs considering the UNICODE character set.

So it is used for string -> number conversion.

I'm not sure, it might even return 1 for I, 5 for V etc (roman numbers).


To get the UNICODE code of a character:
int code = (int)my_character;

Don't forget that char is a UNICODE character in Java.

Dam that's weird. I probably should have used another method in the Character class.

int code = (int)my_character;

Implicit widening conversion no cast needed.



















I just had to say that. {{{laughing}}}

I wasn't sure. I'm never sure with casts between primitive types in Java. I simply do all casts explicitly, it's just easier to see that there is a cast.

[Dillinger4]

Just busting your chops. Explicit casting is always better than implicit that's for sure.

Didn't see the last line of your post.
