What is Java's Primitive Unsigned Integral Type?

char is the only primitive unsigned integral type in Java.

Unsigned means it can have only +ve values.

Other integral types like byte, short, int and long have -ve values.

char ranges from 0 to 65535.

Java does not have a built-in primitive unsigned integral type. The primitive integral types in Java are:
byte (8 bits)
short (16 bits)
int (32 bits)
long (64 bits)
All of these types are signed, meaning they can hold both positive and negative values. However, the closest concept to an unsigned type in Java is using the int and long types to represent unsigned values within their range.
Starting from Java 8, there are also methods in the Integer and Long classes that provide unsigned arithmetic operations, such as Integer.toUnsignedLong(int x) and Long.divideUnsigned(long dividend, long divisor). These methods allow you to work with unsigned integers more effectively, but they don’t create a new primitive type.
If you need to represent large unsigned values, you might consider using the BigInteger class from java.math, which can handle arbitrarily large integers, but keep in mind that it is not a primitive type.
