Why is short 2 bytes?
The size of the short type is 2 bytes (16 bits) and, accordingly, it allows expressing the range of values equal to 2 to the power 16: 2^16 = 65 536. Since the short type is a signed one, and contains both positive and negative values, the range of values is between -32 768 and 32 767.
What is short and byte in Java?
The eight primitive data types supported by the Java programming language are: byte: The byte data type is an 8-bit signed two’s complement integer. short: The short data type is a 16-bit signed two’s complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive).
What does 2L mean in Java?
When you place 2L in code, that is a long literal, so the multiplications promote the other int s to long before multiplication, making your calculations correct by preventing overflow. The basic rules here to know here are: Java has operator precedence.

What is short data type in Java?
The short data type is a 16-bit signed two’s complement integer. Its value-range lies between -32,768 to 32,767 (inclusive). Its minimum value is -32,768 and maximum value is 32,767. Its default value is 0. The short data type can also be used to save memory just like byte data type.
What is a 2 byte integer?
Definitions. An automation integer data type that can be either positive or negative. The most significant bit is the sign bit, which is 1 for negative values and 0 for positive values. The storage size of the integer is 2 bytes. A 2-byte signed integer can have a range from -32,768 to 32,767.
