20 – The Character Data Type in Java Programming
The character type or char is an unsigned integer. Char ranges from 0 to 216-1.All signed character values range from -128 to 127. All unsigned character values range from 0 to 255. The /J compiler option changes the default type for char from signed char to unsigned char .
| Type | Storage size | Value range |
|---|---|---|
| char | 1 byte | –128 to 127 or 0 to 255 |
| unsigned char | 1 byte | 0 to 255 |
| signed char | 1 byte | -128 to 127 |
| int | 2 or 4 bytes | -32,768 to 32,767 or -2,147,483,648 to 2,147,483,647 |

What is the numerical range of a char?
Explanation: The char type is integral but unsigned. The range of a variable of type char is from 0 to 216-1 or 0 to 65535.
What is numerical range of data type?
A range within which any value that satisfies the data type is valid. For example, in a range of 1 to 6 with a decimal data type and scale of 2, values such as 1, 1.03, 2.14, 3, 4.73, 5.2, and 6 are all valid. The interval in this example is null (no value in the Interval field).
Why is char a numeric data type?
Char is an “Integer Data Type” in C and its related progeny. As per the K&R Book, “By definition, chars are just small integers”. They are used for storing ‘Character’ data. The ASCII Table lists 128 characters, and each text character corresponds to an integer value.
What is a char in C?
char is the most basic data type in C. It stores a single character and requires a single byte of memory in almost all compilers. Now character datatype can be divided into 2 types: signed char.
What is the number range of char?
All signed character values range from -128 to 127. All unsigned character values range from 0 to 255. The /J compiler option changes the default type for char from signed char to unsigned char .
What is the numerical range of a char in C?
Explanation: The char type is integral but unsigned. The range of a variable of type char is from 0 to 216-1 or 0 to 65535.
What is range of char in Java?
char: The char data type is a single 16-bit Unicode character. It has a minimum value of ‘\u0000’ (or 0) and a maximum value of ‘\uffff’ (or 65,535 inclusive).
Can a char type be a number?
The CHAR data type stores any string of letters, numbers, and symbols. It can store single-byte and multibyte characters, based on the database locale. The CHARACTER data type is a synonym for CHAR.
What are char values?
The char value is interpreted as an ASCII character. This is similar to how Boolean values are interpreted as being true or false. ASCII is an acronym for American Standard Code for Information Interchange. It defines a specific way of representing English characters as numbers. The numbers range between 0 and 127.
What is the numerical range of a char in Java with UTF 16 encoding?
1. What is the numerical range of a char data type in Java? Explanation: Char occupies 16-bit in memory, so it supports 216 i:e from 0 to 65535.
