There are times, however, when you need to use a char as an object—for 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.

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

In order to achieve this, Java provides wrapper class Character for primitive data type char.

A char value must be surrounded by single quotes, like 'A' or 'c'. Read more about data types in our Java Data Types Tutorial.

A char value is, internally, an unsigned 16-bit integer.

January 23, 2026 - The Character class in Java, available in the java.lang package is a wrapper class used to represent a single char value as an object.

February 26, 2024 - This is a basic way to declare and use a char in Java, but there’s much more to learn about working with chars in Java. Continue reading for more detailed information and advanced usage scenarios. ... In Java, the char keyword is used to declare a character variable.

September 29, 2025 - You can represent a char using its 4-digit hexadecimal Unicode value. ... XXXX: Represents exactly four hexadecimal digits. ... The decimal Unicode value for ‘A’ is 65. ... 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.

Character literals consist of a single quote character (') (ASCII 39, hex 0x27), a single character, and a close quote ('), such as 'w'. Instead of a character, you can also use unicode escape sequences, but there must be exactly one. ... The nominal wrapper class is the java.lang.Character class when you need to store a char value but an object reference is required.

A Character variable in Java programming can store any single character enclosed within single quotes. To declare a variable of type Character we use the keyword char, which is pronounced as ‘kar’.

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).

Java™ Platform Standard Ed. 7 ... The Character class wraps a value of the primitive type char in an object.

In other words, when is a character, ... a character literal — ‘a’ or ‘A’ or ‘0’ or ‘?’ — is always treated as a character, unless we explicitly tell Java to treat it as an integer....

March 31, 2022 - The charAt() method in Java returns the char value of a character in a string at a given or specified index. In this article, we'll see how to use the charAt() method starting with it's syntax and then through a few examples/use cases.

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:
