What is difference between byte short int long in Java?
from the linked page above: 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). int: By default, the int data type is a 32-bit signed two’s complement integer, which has a minimum value of -231 and a maximum value of 231-1.
How many bytes does an int use Java?
4 bytes
Primitive Data Types
| Data Type | Size |
|---|---|
| short | 2 bytes |
| int | 4 bytes |
| long | 8 bytes |
| float | 4 bytes |
What is byte short int long?
byte: -128 to 127. short: -32,768 to 32,767. int: -2,147,483,648 to 2,147,483,647. long: -2^63 to 2^63–1.
What is short and long in Java?
short: The short data type is a 16-bit signed two’s complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive). In Java SE 8 and later, you can use the long data type to represent an unsigned 64-bit long, which has a minimum value of 0 and a maximum value of 264-1.
Why might you want to use a short or int instead of long?
The keyword used is ‘short’. The keyword used is ‘int’. While if there is a need for medium-range value then we can use the type int but when the range for the numeric values will be larger, then the long type variable must be used to hold the values.
What is short int and long int?
The minimum size for char is 8 bits, the minimum size for short and int is 16 bits, for long it is 32 bits and long long must contain at least 64 bits. The type int should be the integer type that the target processor is most efficiently working with.
What is the difference between int and short int?
size of int is 2 bytes and of short int is also 2 bytes. The range of values for int and short int are the same.
What is the difference between int and short in Java?
short datatype is the variable range is more than byte but less than int and it also requires more memory than byte but less memory in comparison to int. The compiler automatically promotes the short variables to type int, if they are used in an expression and the value exceeds their range.
What is the difference between int and long int in Java programming?
In programming languages such as Java, the programmer should specify the data type. If the variable is declared as an int, then he cannot assign a character value to it. The key difference between int and long is that int is 32 bits in width while long is 64 bits in width.
