Checking Character Properties (The Java™ Tutorials > Internationalization > Working with Text)
Unicode is a 16-bit character encoding that supports the world's major languages. In the Java programming language char values represent Unicode characters. If you check the properties of a char with the appropriate Character method, your code will work with all major languages.

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
...and so on

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.

September 14, 2021 - toString(char ch): Returns a String object representing the specified character value — that is, a one-character string. The Java platform has supported Unicode Standard starting with JDK 1.0.2. Java SE 15 supports Unicode 13.0. The char data type and the Character class are based on the original Unicode specification, which defined characters as fixed-width 16-bit entities.

Char Data Type in Java
April 24, 2025 - The char data type in Java is a primitive type that holds a single character, like a letter, digit, or symbol. It's stored in 16 bits (2 bytes), unlike some languages that use 8 bits, giving it room for 65,536 possible values

Almost nobody seems to answer your question, what is the point of it, how is that type useful? The answer is simple, because you can do some nice things with chars. You can turn an uppercase into a lowercase letter and the other way around, by changing a single bit: public char toLower(char c) { return c | 0x20; } public char toUpper(char c) { return c & ~0x20 } public char toggleLowerUpper(char c) { return c ^ 0x20 } These (and other) bitwise operations make no sense on strings, but they do on chars. Also, there are methods specifically directed at string. How are you gonna write a method that removes whitespaces, if you can't even detect whether a character is a whitespace? For most things, a string of length 1 is as good as a char, if you ignore the tiny performance penalty, but sometimes you have to work on chars.

January 1, 1998 - One of the many principles laid down in the design of the Java language was that characters would be 16 bits. This choice supports the use of Unicode, a standard way of representing many different kinds of characters in many different languages.

char is a primitive type that represents a single 16 bit Unicode character while Character is a wrapper class that allows us to use char primitive concept in OOP-kind of way.
Example for char,
char ch = 'a';
Example of Character,
Character.toUpperCase(ch);
It converts 'a' to 'A'

From the JavaDoc:
The Character class wraps a value of the primitive type char in an object. An object of type Character contains a single field whose type is char. In addition, this class provides several methods for determining a character's category (lowercase letter, digit, etc.) and for converting characters from uppercase to lowercase and vice versa.
Character information is based on the Unicode Standard, version 6.0.0.
So, char is a primitive type while Character is a class. You can use the Character to wrap char from static methods like Character.toUpperCase(char c) to use in a more "OOP way".
I imagine in your program there was an 'OOP' mistake(like init of a Character) rather than char vs Character mistake.

char is actually an integer type. It stores the 16-bit Unicode integer value of the character in question.
You can look at something like http://asciitable.com to see the different values for different characters.

In Java char literals represent UTF-16 (character encoding schema) code units. What you got from UTF-16 is mapping between integer values (and the way they are saved in memory) with corresponding character (graphical representation of unit code).
You can enclose characters in single quotes - this way you don't need to remember UTF-16 values for characters you use. You can still get the integer value from character type and put if for example in int type (but generally not in short, they both use 16 bits but short values are from -32768 to 32767 and char values are from 0 to 65535 or so).
