primitive data types in java 文心快码BaiduComate 在Java中,原始数据类型(Primitive Data Types)是编程语言中内置的基本数据类型,它们直接存储在内存中,而不是作为对象的引用。这些类型提供了对基本数据操作的直接支持,使得程序能够高效地处理数据。 Java中的所有原始数据类型包括: byte: 描述:8位有符号整数。 范围...
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 ...
