Calculated Hex to Unicode for display in label

Question

Hi
I want to calculate an integer, convert to unicode and display the appropriate character in a label. I can display the correct chinese character if I pass a string literal e.g. "\u4e00" to the setText method. But I dont want to have hardcoded string literals in my program. Of course the compiler insists on having the complete string before hand (i.e. cannot add the "\u" to my calculated hex string). So how can I get the label to display the actual character using just the hex number? Is it possible?
TIA

using just the hex number? Is it possible?Sure it is; don't be misled by all that hexadecimal stuff. A character is just an
integer value in the range 0x000 - 0xffff (two bytes unsigned numbers). Here's
a small example:JLabel lab= new JLabel();
char c= 0;
do {
   lab.setText("A char: '"+c+"'");
   // do something with the label;
} while (++c != 0);kind regards,
