二維與多維陣列

資料型態 陣列名稱[][];
陣列名稱＝new 資料型態[列的個數][行的個數];  //而列的個數一定要填

int score[][];   //宣告整數陣列score
score=new int[2][4]; //使陣列score 可存放2列4行的記憶體空間

資料型態 陣列名稱[][]＝new 資料型態[列個數][行個數]; //列的個數一定要填

int score[][]=
{   
  {15,25,30,17},
  {22,52,10,8}
};

public class ch06_4 {
​
	public static void main(String[] args) {

		for(i=0; i<score.length; i++)
		{
		   for(j=0; j<score[i].length; j++) //這此運用到取得第i列的元素個數
		   {
		      System.out.println("score["+i+"]["+j+"]="+score[i][j]);

		}
		System.out.println("陣列行數："+score.length);
