What is the Difference Between int and long?
🆚 Go to Comparative Table 🆚The main difference between int
and long
data types lies in their size, range, and memory requirements. Here is a comparison between the two:
- Size: An
int
is a 32-bit integer, while along
is a 64-bit integer. - Range: The range of an
int
in Java is between -2,147,483,648 and 2,147,483,647. The range of along
in Java is much larger, between -9,223,372,036,854,775,808 and 9,223,372,036,854,775,807. - Memory Requirements: An
int
requires 4 bytes (32 bits) of memory, while along
requires 8 bytes (64 bits) of memory.
In general, you should choose the appropriate data type based on the range of numeric values you expect to work with. If the range of values is within the scope of an int
(32 bits), it is more efficient to use an int
due to its lower memory requirements. However, if the range of values requires a larger data type, such as a long
(64 bits), you should use a long
to avoid unexpected behavior or data loss.
Comparative Table: int vs long
The main difference between int
and long
data types lies in their size, range, and memory requirements. Here is a table summarizing the differences between int
and long
in Java:
Property | int | long |
---|---|---|
Memory required | 4 bytes (32 bits) | 8 bytes (64 bits) |
Range | -2^31 to 2^31 - 1 (-2,147,483,648 to 2,147,483,647) | -2^63 to 2^63 - 1 (-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807) |
Default Value | 0 | 0L |
In Java, the int
data type is the most commonly used type for numeric values and is a signed 32-bit integer, while the long
data type is less frequently used and is a signed 64-bit integer. The int
data type requires 4 bytes of memory and has a range of -2^31 to 2^31 - 1, while the long
data type requires 8 bytes of memory and has a range of -2^63 to 2^63 - 1.
