Kotlin has almost the same data types as Java. The following table lists them:
Data type | No. of bytes | No. of bits |
Byte | 1 | 8 |
Short | 2 | 16 |
Int | 4 | 32 |
Long | 4 | 32 |
Float | 8 | 64 |
Double | 8 | 64 |
The only visible difference is that Kotlin has the data type Int as opposed to Integer in Java.
