Java中数组的用法

public class HowToUseArray {

    public static void main(String[] args)

    {


        //Correct usage 
 

        int [] ary;

        

        int [] aryA = {1,2};

        

        int [] aryB = new int[2];

        aryB[0] = 1;

        aryB[1] = 2;

        

        int [] aryC = new int[]{1,2};

        

        //Wrong usage

        

        //int [] aryD = new int[2]{1,2};

　　　　 //Cannot define dimension expressions when an array initializer is provided


        //int aryE[4];

    }
