In Java byte, short, int and long all of these are
A. signed
B. unsigned
C. Both of the above
D. None of these
Answer: Option A
Solution (By Examveda Team)
In Java, byte, short, int, and long are all signed integer data types.Here's the breakdown:
Option A: signed - This option is correct. byte, short, int, and long are all signed integer data types in Java, which means they can represent both positive and negative whole numbers.
Option B: unsigned - This option is not correct. Java does not have built-in unsigned integer data types. Unlike some other programming languages, all integer data types in Java are signed by default.
Option C: Both of the above - This option is not correct because only Option A is true. Java integer data types are signed, not unsigned.
Option D: None of these - This option is not correct because Option A is the correct answer. Java's byte, short, int, and long are all signed integer data types.
So, in Java, byte, short, int, and long are all signed integer data types.
This Question Belongs to Java Program >> Data Types And Variables
byte: 8-bit signed integer. Can hold values from -128 to 127.
short: 16-bit signed integer. Can hold values from -32,768 to 32,767.
int: a 32-bit signed integer. Can hold values from -2,147,483,648 to 2,147,483,647.
long: a 64-bit integer. Can hold really big numbers (-2^63 to 2^63–1).
The answer will be signed because these data types consist of both positive and negative values.
THANK YOU
may i know the explanation of this question please.
Only "String" is unsigned, signed data means the data has to be declared before we use it.
