Each type has its corresponding range,for instance:byte is used for integers between -128 ~ +127 Example given:int age = 20 The statement tells the computer to ▪ Allocate space in memory to hold data of int

Like bytes, short types are useful alternatives to int (see below) data types, particularly if your data falls within the specified range. As with byte, using short also improves code readability, besides saving memory. 3. Int:An integer is four times the size of a byte (i.e. it is m...
double: The double data type is a double-precision 64-bit IEEE 754 floating point. Its range of values is beyond the scope of this discussion, but is specified in the Floating-Point Types, Formats, and Values section of the Java Language Specification. For decimal values, this data type is...
Java Datatype has a range, i.e. represented by a minimum and maximum. Primitive Data Types include the byte, short, boolean, int, long, float, double and char type. Following are the minimum and maximum value of primitive data types in Java: ...
Java Data Type The data type of the variable determines therange of the valuesthat the memory location can hold. Therefore, the amount ofmemory allocated for a variable depends on its data type. For example, 32 bits of memory is allocated for a variable of the'int'data type. ...
147,483,648 to 2,147,483,647. In addition to other uses, variables of type int are commonly employed to control loops and to index arrays. This data type will most likely be large enough for the numbers your program will use, but if you need a wider range of values, use long ...

Primitive Types: 1) byte: size: 8-Bit = 1-Byte range: -128~+127 usage: 1> The byte data type can be useful for saving memory in large arrays, where memory saving actually matters. 2> They can also be used in place of int where their limits help to clearify your code. The fact...
