JAVA 数组

public class Test{
    public static void main(String[] args){
        int[] arr    =    new    int[5];    //声明数组，并赋值最大有5个，下标是0-4
        arr[1]    =    99;    //给数组的下标1赋值
        arr[2]    =    88;    //给数组的下标2赋值
        int i    =    arr[1]    //数组下标值的引用
        System.out.println(i);
    }
}

public class Test{
    public static void main(String[] args){
        //第一种
        int arr1[];
        arr1    =    new int[5];
        arr1[0]    =    10;
        //第二种
        int[] arr2    =    new int[5];
        arr2[0]    =    20;
        //第三种
        int[]    arr3    =    {30,40,50};
    }
