What is a 64-bit integer in Java?
The size of an int in Java is completely independent of the 32-bitness or 64-bitness of a JDK. It is always 4 bytes = 32 bits = −2,147,483,648 to 2,147,483,647. If you want a 64-bit integer, use a long , which is always 64 bits = 8 bytes.

How big is an int in Java?
32 bits
Also known as an integer, int type holds a wide range of non-fractional number values. Specifically, Java stores it using 32 bits of memory. In other words, it can represent values from -2,147,483,648 (-231) to 2,147,483,647 (231-1).

Can we give size to int in SQL?
The range of an int data type is -2,147,483,648 to 2,147,483,647.
How do I change the int size in SQL?
If you want to limit the range of an integer column you can use a check constraint: create table some_table ( phone_number integer not null check (phone_number between 0 and 9999999999) );
How many 64-bit integers are there?
A 64-bit register can hold any of 264 (over 18 quintillion or 1.8×1019) different values. The range of integer values that can be stored in 64 bits depends on the integer representation used.
How many digits is 64-bit?
As a recap, remember that the maximum number stored in a 64 bit register / variable is 2^64 – 1 = 18446744073709551615 (a 20 digit number).
Is the size of an int in Java 32 bits or 64 bits?
So you might be running your program in a 64 bit machine, but an int is going to be always 32 bit long so it will have the same range. This is true for both C# and Java. Here is a full article on the matter: Integral data types in Java and C#.
How big is a 64bit integer in MySQL?
In MySQL, the BIGINT datatype represents an 8 byte (64-bit) integer. It can be SIGNED or UNSIGNED which permits (or prevents) negative numbers in the column.
How big is a small int in SQL?
int, bigint, smallint, and tinyint (Transact-SQL) Data type Range Storage bigint -2^63 (-9,223,372,036,854,775,808) to 2^ 8 Bytes int -2^31 (-2,147,483,648) to 2^31-1 (2,147, 4 Bytes smallint -2^15 (-32,768) to 2^15-1 (32,767) 2 Bytes tinyint 0 to 255 1 Byte
Which is the bigint data type in SQL Server?
bigint fits between smallmoney and int in the data type precedence chart. Functions return bigint only if the parameter expression is a bigint data type. SQL Server does not automatically promote other integer data types ( tinyint, smallint, and int) to bigint. Caution.
