1.数组就是一组数据，数据类型相同

2.数组的声明

3.数组的初始化

 

package org.cindy.array;public class Array {    public static void main(String[] args) {        //int[] x = new int[5]; //声明数组长度                /*        x[0] = 1;        x[1] = 2;        x[2] = 3;        x[3] = 4;        x[4] = 5;        */                int[] x = new int[]{1,2,3,4,5};                for (int i = 0; i < x.length; i++){            System.out.println(x[i]);        }                //char[] c = new char[3];        //c[0] = 'a';        //c[1] = 'b';        //c[2] = 'c';        char[] c = new char[]{'a', 'b', 'c'};        for (int j = 0; j < c.length; j++){            System.out.println(c[j]);        }        //float[] f;        //String[] s;    }}
