Java学习----数组

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;
    }
}
