Are there unsigned primitive data types?

In Java, primitive data types such as byte, short, int, long, char, float, double, and boolean are mostly signed, except for the char type, which is an unsigned 16-bit type representing Unicode characters.

That is, the only unsigned primitive type in Java is char. For integer types (byte, short, int, long), there are no unsigned primitives, but starting from Java 8, methods have been introduced to work with them as unsigned (for example, Integer.toUnsignedLong).
