![]() ![]() 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.
