+|---------------|--------------------------|
+| Size          | 8 bytes (64 bits)        |
+|               | (`-2⁶³`) to (`2⁶³ - 1`)  |
+
+## The all Data Types in above (byte, short, int, long) represent only integral values, not decimals.
+
+---
+
+> When working with integer values, we use `byte` for the shortest range, `short` for a larger range than `byte`, `int` for a widely used default range, and `long` for very large values.
+
+**For decimal values, we use `float` for single-precision and `double` for double-precision.**
