Java SE 第二讲: 1. Windows: notepad, editplus, ultraedit, gvim Linux: vi, vim, gedit 2. Java 中的数据类型分为两大类: 1)原生数据类型 (Primitive Data Type) 2)引用类型(对象类型) (Reference Type) 3. 变量与常量:所谓常量,就是值不
The most commonly used integer type is int. It is a signed 32-bit type that has a range from –2,147,483,648 to 2,147,483,647. In addition to other uses, variables of type int are commonly employed to control loops and to index arrays. This data type will most likely be large ...

Doing so tells your program that a field named "gear" exists, holds numerical data, and has an initial value of "1". A variable's data type determines the values it may contain, plus the operations that may be performed on it. In addition to int, the Java programming language supports...
considered a primitive data type in one language but not in another. Other experts may contrast primitive data types with derived data types, which are created using collections of primitive data types. As a result, they can be broken down into more basic elements than the primitive data types...
