short to long Java

short to long Java

After knowing primitive data types and Java rules of Data Type Casting (Type Conversion), let us cast short to long as an example.

The short takes 2 byte of memory and long takes 8 bytes of memory. Assignment 2 bytes of memory to 8 byte of memory is done implicitly. This is known as widening conversion. This is like pouring smaller bottle water in a bigger bottle.

See the data types order to know the brief rules of casting.

byte –> short –> int –> long –> float –>double

The left-side value can be assigned to any right-side value and is done implicitly. The reverse like int to short requires explicit casting.

Examples of implicit casting

Following example on short to long explains the Java syntax where a short value is implicitly assigned to a long value.
