The ASCII value of a is 97.
When i = 0, i + 'a' = 0 + 97 => When cast into char, it will be a
When i = 1, i + 'a' = 1 + 97 => When cast into char, it will be b
When i = 2, i + 'a' = 2 + 97 => When cast into char, it will be c

There are times, however, when you need to use a char as an objectfor example, as a method argument where an object is expected. The Java programming language provides a wrapper class that "wraps" the char in a Character object for this purpose. An object of type Character contains a single field, whose type is char.

The ASCII value of a is 97.
When i = 0, i + 'a' = 0 + 97 => When cast into char, it will be a
When i = 1, i + 'a' = 1 + 97 => When cast into char, it will be b
When i = 2, i + 'a' = 2 + 97 => When cast into char, it will be c

Java char is a 16-bit integral type. 'a' is the same as 97, which you can see with System.out.println((int) 'a'); - it follows that 98 is 'b' and so on across the entire ASCII table.

Reading the remainders from bottom to top gives 41. The hexadecimal representation must be 4 digits, so we pad it with leading zeros: 0041. Combine with the \u prefix and enclose in single quotes. ... Java provides special backslash (\) literals, known as escape sequences, to represent non-printable or special characters.

Interactive Algorithms Textbook in Java: Strings And Chars
Internally, Strings are actually arrays of characaters. However, in Java, we cannot use square brackets to get a single character out of a String. Instead, if we wanted the first character in "Hello" (the 'H'), we would use the expression "Hello".charAt(0). The second character would be "Hello".charAt(1), and the last character would be "Hello".charAt(hello.length()-1).

January 16, 2024 - We’ll briefly discuss how characters are represented in order to better understand the code we’ll see later in the article. Internally, Java stores each char as a 16-bit Unicode encoded value:
Top answer 1 of 11

In Java, char is a numeric type. When you add 1 to a char, you get to the next unicode code point. In case of 'A', the next code point is 'B':
char x='A';
x+=1;
System.out.println(x);
Note that you cannot use x=x+1 because it causes an implicit narrowing conversion. You need to use either x++ or x+=1 instead.

char is a numeric type (2 bytes long), and is also the only unsigned numeric primitive type in Java.
You can also do:
int foo = 'A';
What is special here is that you initialize the char with a character constant instead of a number. What is also special about it is its string representation, as you could witness. You can use Character.digit(c, 10) to get its numeric value (as an int, since 2 ^ 16 - 1 is not representable by a short!).
