数组“类”型

package test_pakages;

public class ArraySize {

    public static void main(String[] args){
        Array[] ArrayB = new Array[5];
        int[] ArrayC = new int[5];
        double[] ArrayD = new double[5];

        for(int i= 0;i<ArrayC.length;i++){
            ArrayC[i] = i;
            ArrayB[i] = new Array(ArrayC[i],ArrayC[i]);
        }
        for(int i= 0;i<ArrayD.length;i++){
            ArrayD[i] = Math.atan(i);
            ArrayB[i] = new Array(ArrayD[i]);
        }
    }
}
class Array{
    public Array(int i){
        System.out.println("int整形数"+i);
    }
    public Array(double i){
        System.out.println("double数"+i);
    }
    public Array(int i,int j){
        System.out.println("相乘数组"+i*j);
    }

}
