Java中的基本数据类型 Java是一种强类型语言。这意味着必须为每一个变量声明一种类型。在Java中,一共有8种基本 类型(primitive type),其中由4种整型、2种浮点类型、1种用于表示Unicode编码的字符单元 的字符类型char和1种用于表示真值的boolean类型。 在Java中,所有的数值类型所占据的字节数量与平台无关。注意,...

The eight primitive data types supported by the Java programming language are: 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 ...
Java, for instance, has eight primitive data types: boolean– a single TRUE or FALSE value (typically only requires onebit) byte– 8-bit signed integer (-127 to 128) short– 16-bit signed integer (-32,768 to 32,767) int– 32-bit signed integer (-231to -231-1) ...
Primitive Data Type A primitive data type is either a data type that is built into a programming language, or one that could be characterized as a basic structure for building more sophisticated data types. Programmers will often be immediately familiar with the primitive data types used in ...
The term primitive in this context is usually discussed in relationship to data types. For example, the Java data types int, char and Boolean are all considered primitive types. Other Java types are built on the primitive types. The term primitive might also be used in other ways in a ...
