WebJava supports eight basic data types known as primitive types. In addition, it supports classes and arrays as composite data types, or reference types. Classes and arrays are documented later in this chapter. The primitive types are: a boolean type, a character type, four integer types, and two floating-point types.

WebThere are eight so-called primitive types built into Java. The primitive types are named byte, short , int, long, float, double, char , and boolean. The first four types hold integers (whole numbers such as 17, -38477, and 0). The four integer types are distinguished by the ranges of integers they can hold. Web27 mrt. 2024 · Primitive data type double uses 64 bits, and has a much greater range, -1.7E+308 to +1.7E+308. It also has a much greater precision: about 15 significant decimal digits. Because of this, if you write a literal like 2.345 in a Java program, it will automatically be regarded as a double, even though a float might be good enough.
