In this post, we will understand the difference between ‘int’ and ‘long’ types.

int

• It is a datatype.

• It has 32-bits.

• In terms of bytes, it takes up 4 bytes.

• In Java, it is between the range –2,147,483,648 to 2,147,483,647.

• It is also used as a keyword to declare variable of type integer.

• In comparison to memory required to store ‘long’ variables, it takes up less memory space.

long

• It is a data type.

• It takes 64-bits.

• In terms of bytes, it takes 8 bytes.

• In Java, its range is between –9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.
