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.
