Java converting keycode to string or char

Question

I want to turn keyevent keycode value into a string or a char value. Either one would do.

For example, when I press 'SPACE', which 'lets say' has a keycode 20, and I want to convert that value to a char or a string. Is there any standard way of doing so, or I have to write a bunch of 'if' statements for every key on the keyboard?

Do you mean something like KeyEvent.getKeyText()? – Gaynell

Answer 1

Cast it to Char.

Char c=(Char)keycode;

that was simple O_O Thanks! – Stratigraphy

Answer 2

If e is the variable parameter of the KeyEvent, use

 e.getKeyText(e.getKeyCode())

But preferably use it in a static context of KeyEvent

KeyEvent.getKeyText(e.getKeyCode())

It returns a string but you can cast to or get value of string returned in other parsable data types

Answer 3

Just cast it to a character, but not with capital c:

char c = (char) 20;

Answer 4

One way could be to load all the values in a Map and just get the value for each key pressed. Like if you press a SPACE-KEY and get input as 20, just get the value associated with that key from the map and use it.

Answer 5

Another option similar to Reujoe is to use getKeyChar() if you have they KeyEvent variable.

e.getKeyChar()

It returns the character representation of the keycode as a Char
