What is the default value of byte data type in Java?
|Data Type||Default Value (for fields)|
Similarly, you may ask, what is the default data type?
Certain columns and data types have predefined or assigned default values. For example, default column values for the various data types are as follows: NULL. 0 Used for small integer, integer, decimal, single-precision floating point, double-precision floating point, and decimal floating point data type.
One may also ask, what is the default value of an object in Java? Default values are same as instance variables. For numbers, the default value is 0; for Booleans, it is false; and for object references, it is null. Values can be assigned during the declaration or within the constructor.
Then, what are the default values of Java primitive data types?
In Java, the default value of any primitive is the 'zero' equivalent of that primitive. int,float,double are 0, char is u0000, boolean is false. Since primitives are not actually objects on their face in Java, then they must be initialized by default because, semantically, they can never be null.
What is byte data type in Java?
byte: The byte data type is an 8-bit signed two's complement integer. It has a minimum value of -128 and a maximum value of 127 (inclusive). The byte data type can be useful for saving memory in large arrays, where the memory savings actually matters.
