What is char Keyword in Java

The char keyword is a data type. You can store a character such as ‘A’, ‘a’ etc to the char variable.

Important Points:

The value assigned to a char data type is provided in single quotes such ‘Q’, ‘h’ etc.
You can also pass integer numbers ranging from 0 to 65,535 to a char variable, these values are treated as ASCII characters. For example, passing 72 value to a char type variable will print ‘H’, if you print the value of that variable.
It is a single 16-bit unicode character. The min value is '\u0000' (or 0) and max value is 'uffff' (or 65,535).

Example of char Keyword

public class JavaExample {
  public static void main(String[] args) {
    char ch1 = 'A';
    char ch2 = 'p';
    System.out.println(ch1);
    System.out.println(ch2);
  }
}

Output:

A
p

Example 2: Passing ASCII value to char type variable

public class JavaExample {
  public static void main(String[] args) {
    char ch1 = 72;
    char ch2 = 125;
    System.out.println(ch1); //prints 'H'
    System.out.println(ch2); //prints '}'
  }
}

Output:
