How do you convert a number to a character?

Example 1: Java Program to Convert int to char char a = (char)num1; Here, we are using typecasting to covert an int type variable into the char type variable. To learn more, visit Java Typecasting. Note that the int values are treated as ASCII values.

How is a char stored in Java?

In Java, char is short for character. It’s 16 bits in size – double that of a byte. Most of the time however, the actual data stored in the char data type doesn’t take up more than 8 bits. The reason Java allows 16 bits is so that all characters in all human languages can be represented.

What can we store in char in Java?

The Java char keyword is a primitive data type. It is used to declare the character-type variables and methods. It is capable of holding the unsigned 16-bit Unicode characters.
