That every element of the float value set is necessarily also anĮlement of the float-extended-exponent value set, the double value The constraints in Table 4.1 are designed so Positive zero, negative zero, positive infinity, and negative The four value sets includes not only the finite nonzero values thatĪre ascribed to it above, but also NaN values and the four values There is a specific implementation-dependentĬonstant K, whose value is constrained by Implementation, then for each supported extended-exponent value set Or both extended-exponent value sets are supported by an Required and two optional floating-point value sets are summarized in Is said to be a denormalized value, because it Value in a value set cannot be represented in such a way Representation is said to be denormalized. Value v in a value set might be represented inīy 1 to produce a second representation for the same Some values can be represented in thisįorm in more than one way for example, supposing that a Instead of the standard value sets to represent the values ofĮxpressions of type float or double ( §5.1.13,įinite nonzero values of any floating-point value set can all be TheseĮxtended-exponent value sets may, under certain circumstances, be used The float-extended-exponent value set and Sets of floating-point values, called the float valueĪddition, an implementation of the Java programming language may support either orīoth of two extended-exponent floating-point value sets, called Implementation of the Java programming language is required to support two standard NaNĬonstants of both float and double type are predefined A NaN value is used to represent the result ofĬertain invalid operations such as dividing zero by zero. In IEEE Standard for Binary Floating-PointĪrithmetic, ANSI/IEEE Standard 754-1985 (IEEE, Newħ54 standard includes not only positive and negative numbers thatĬonsist of a sign and magnitude, but also positive and negative zeros,Ībbreviated NaN). Integer operators do not indicate overflow orĤ.2.3. Floating-Point Types, Formats, and Valuesįloating-point types are float and double, which are conceptuallyĪssociated with the single-precision 32-bit and double-precisionĦ4-bit format IEEE 754 values and operations as specified There are no castsīetween integral types and the type boolean. Type may be cast to or from any numeric type. If either operand is not an int, it is first widened to type Otherwise, the operation is carried out usingģ2-bit precision, and the result of the numerical operator is of type ( §5.1.5) to type long by numeric promotion If the other operand is not long, it is first widened Precision, and the result of the numerical operator is of type Of type long, then the operation is carried out using 64-bit Integer operator other than a shift operator has at least one operand Methods, and constants are predefined in the classes Byte, Short, In decimal form, and then produce a newly created String that is Which, when given a String operand and an integral operand, willĬonvert the integral operand to a String representing its value Value to a value of any specified numeric type ( §15.16), which can convert from an integral Objects, including arrays, support the methods of class Object

The values of a reference type are references to objects. An object ( §4.3.1) is aĭynamically created instance of a class type or a dynamically createdĪrray.

The reference types ( §4.3)Īre class types, interface types, and array types. Short, int, long, and char, and the floating-point typesįloat and double. The numeric types are the integral types byte, Primitive types ( §4.2) are the boolean type and The types of the Java programming language areĭivided into two categories: primitive types and reference types. Static typing helps detect errors at compile time. Those values, and determine the meaning of the operations. That an expression can produce, limit the operations supported on The values that a variable ( §4.12) can hold or Types, Classes, and InterfacesĪ statically typed language, which means thatĮvery variable and every expression has a type that is known atĪ strongly typed language, because types limit Subtyping among Class and Interface Types 4.10.3.
