In Java, converting a `double` to a `char` is possible through explicit casting, but you must be aware of potential data loss. A `char` is a 16-bit unsigned integer representing a Unicode code point (range 0 to 65,535), while a `double` is a 64-bit floating-point value.
Basic conversion (explicit cast)
```java
double d = 65.5; // example value
char c = (char) d; // c becomes 'A' (ASCII 65) — fractional part is truncated
```
- The fractional part of the `double` is truncated (not rounded).
- If the truncated integer value is outside the `char` range (0–65535), the result will wrap modulo 65536 (e.g., `(char) -1` becomes `65535`).
