JAVA has 8 reserved keyword for primitive data type for assigning 8 different type of information based on value (type of information) and byte (memory or space). For example int is used for a 32-bit (4-byte) integer value, char for 16-bit character, boolean for true or false value, ...
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...

Java supports eight basic primitive data types. This tutorial explains basic primitive data types (int, long, short, byte, char, boolean, float, double) with their size, range and default value. Java basic data types are predefined and implicit to the la
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 ...

【答案】：variables of a primitive type declared是定义的原始类型的变量，是指int,long,char,boolean等原始类型，这些不是类，在.Net里叫做小整形，小长型，小字符，这些变量即使在传递的时候也是传递自己的一个复制。（最后这句看不懂没关系，看下面的你就懂了）reference variables declared 是定义...
boolean 布尔型 true 或 false bype 一个字节 -128-127;bype b=125;(符号占一位,) char 两个字节 0-65535 int 4个字节的整数 long 8个字节的整数 float 4个字节的浮点数(单精度)//浮点数是指小数位数不确定的小数。6-7位精度 double 8个字节的浮点数(双精度)14-15位精度。
It is very easy to declare a double in Java: doubled=3.13457599923384753929348D;doubled; Just like float, the default value of a double type is 0.0. 7. boolean A boolean is actually one of the most simple primitive data types in Java. As you may already know, a boolean can contain onl...
