Java Basic Concepts
In this lesson, we will learn about Character variable in Java programming with the help of some examples. We will also play a quiz on it at the end.
What is Character Variable
A Character variable in Java programming can store any character enclosed within single quotes. To declare a variable of type character we use the keyword char (pronounced as kar).
