To obtain the ASCII value of a character, simply assign the char variable to an int variable. For example:

 char aChar='B';int charVal = aChar;

Then System.out.println(“”+charVal); will print the ASCII value of ‘B’ which is 66. On the other hand, to obtain the character representing an ASCII value, you’ll need a simple cast like:

 int charVal = 66;char aChar  = (char)charVal;

Then System.out.println(“”+aChar); will print B, which represents ASCII 66.
