二维数组【java】

 

二维数组赋值内存地址

public class DouArr{
	public static void main (String args[]){
		int arrA [] = {12,23,34,45};
		int [] arrB= new int [] {90,19,80,78};
		int arrC [] = new int [2];
		System.out.println("分别打印一维数组的地址");
		System.out.println("arrA="+arrA+"\tarrB="+arrB+"\tarrC="+arrC);
		//以上是一维数组
		//以下是二维数组
		System.out.println("分别打印二维数字的地址");
		int arrDouble [] [] = new int [3] [];
		for (int i=0;i<arrDouble.length;i++){
			System.out.print(arrDouble[i]+"\t");
		}
		System.out.println("打印换行");
		//二维数组的内容
		arrDouble[0] = arrA;
		arrDouble[1] = arrB;
		arrDouble[2] = arrC;
		System.out.println("打印二维数组的地址");
		for(int i=0;i<arrDouble.length;i++){
			System.out.println(arrDouble[i]);
		}
	}
