Which data type requires the least amount of memory in Java?
byte datatype has a range from -128 to 127 and it requires very little memory (only 1 byte).
What is the memory requirement of Java primitive data types?
2.1. Primitive Data Types
| Data Type | Description | Memory Size |
|---|---|---|
| byte | values values from -128 to 127 | 8 bit signed value |
| short | values values from -32768 to 32767 | 16 bits signed value |
| int | values values from from -231 to 231-1 | 32 bits signed value |
| long | values values from from -263 to 263-1 | 64 bit floating point value |
Which of the following data types is the largest?
Explanation: ‘double’ is the longest data type with 64-bit defined by Java to store floating-point values.
Is byte smaller than int?
byte: The byte data type is an 8-bit signed two’s complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive)….Default Values.
| Data Type | Default Value (for fields) |
|---|---|
| byte | 0 |
| short | 0 |
| int | 0 |
| long | 0L |
How many data types are there in Java?
There are 8 primitive data types in Java: byte, char, short, int, long, float, double and boolean. These data types act as the basic building blocks of data manipulation in Java.
What is the range of data type in Java?
Data types in Java are classified into two types: Primitive—which include Integer, Character, Boolean, and Floating Point….1. Integer.
| Type | Size | Range of values that can be stored |
|---|---|---|
| byte | 1 byte | −128 to 127 |
| short | 2 bytes | −32768 to 32767 |
| int | 4 bytes | −2,147,483,648 to 2,147,483,647 |
How much memory primitive data types require?
byte. byte is a primitive data type similar to int, except it only takes up 8 bits of memory. Thus, why we call it a byte.
Which primitive type can hold the largest value?
Summary of Data Types
| Primitive Type | Size | Maximum Value |
|---|---|---|
| byte | 8-bit | +127 |
| short | 16-bit | +215-1 (32,767) |
| int | 32-bit | +231-1 (2,147,483,647) |
| long | 64-bit | +263-1 (9,223,372,036,854,775,807) |
What is the largest integer group data type in Java?
Int. The int data type can store whole numbers from -2147483648 to 2147483647.
What is byte type?
The BYTE data type stores any kind of binary data in an undifferentiated byte stream. Binary data typically consists of digitized information, such as spreadsheets, program load modules, digitized voice patterns, and so on. The term simple large object refers to an instance of a TEXT or BYTE data type.
