A char example
The example below declares and uses char data type variables. The char variable is assigned a value and then we will display it by using the System.out.println statement.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | public class variable_example { public static void main(String []args) { char a; char b=‘B’; a=‘A’; System.out.println(b); // Java Variable example } } |
As you run code the output will be:
B
