Java 数组详解：一维数组+二维数组+数组拷贝

一.一维数组（1）数组是什么数组可以装一组相同数据类型数据的容器（变量）数组是一个可以装其它数据(基本类型数据或者引用类型数据即对象)的容器它也是一个对象的,也是在堆空间里分配数组类型本身是一个引用类型(由其它类型加上[])int a = 9; - 基本数据类型int[] ages = new int[20] - 引用类型（2）声明 1 int[] arr ;//声明数组变量arr = new int[3];//给数组分配内存空间，而且默认值是0 2 int[] arr = new int[3];//定义一个数组变量，并分配内存空间，默认值为0 （3）初始化 1 声明和初始化分开 int[] arr = new int[3];//给数组变量分配内存空间，赋以相应数据类型的默认值。 arr[0] =3; arr[1] =7; arr[2] =9; java.lang.ArrayIndexOutOfBoundsException数组下标越界异常。 2 声明和初化合在一起 int[] arr = new int[]{3,7,9}; int[] arr = {3,7,9}; 数组的每个...

Java 基本数据类型+引用数据类型详解

一.数据类型 java是强类型语言，指的是一旦一个常量或变量声明出来，它的类型就确定了，以后都不会变成其它类型，声明的时候是整型，以后都是整型(ps:javascript是弱类型)var i =10;si = "hello";var d =new Date(); int i =10;i ="hello";//XXXXXX java的数据类型包括哪些呢？int a = 6;Scanner input = new Scanner(System.in); 基本数据类型只有8个:byte、short、int、long、float、double、char、boolean 注意:　String不是基本数据类型！！！是引用类型引用数据类型有无限个二.数学进制（1）十进制日常生活中使用的进制都是十进制，因为古人数数只能用10个手指头，满10进1基数有10个，0到9，满10进1 7332 = 7 * 10（3） + 3*10（2） + 3*10（1） + 2*10（0）（2）二进制 1 二进制是谁发明？如何发明的18世纪德国数理哲学大师莱布尼兹发现部分灵感来源于中国古代哲学，如易经二进制转成...
