What data categories allow storing negative numbers?

In Java, negative numbers can be stored in the following data types:

• byte — 8-bit signed integer, range from -128 to 127.
• short — 16-bit signed integer, range from -32768 to 32767.
• int — 32-bit signed integer, approximately from -2 billion to +2 billion.
• long — 64-bit signed integer, very large range.

Floating point types — float and double — can also store negative numbers with fractional parts.

Example:

int negativeNumber = -42;
double negativeDouble = -3.14;
