In Java, all variables must be declared before used in the program. To declare a char variable in Java, specify the char followed by the variable name and optionally assign a value. Below are the syntax and the examples:
Syntax
char identifier [ = value ], identifier [ = value ]...];
 Examples
char cityName = 'Delhi'; char char1, char2; char char1 = 'x', char2;
Java Program Example Using char Variable
class CharVarDemo { public static void main (String args[]) { char char1, char2; char1 = 88; // ascii code for X char2 = 'Y'; System.out.print ("char1 and char2: "); System.out.println (char1 + " " + char2); } }
Output
char1 and char2: X Y
