標題:
陣列的長度
利用length屬性, 可取得陣列的長度, 即該陣列包含了幾位成員.
int a[]={1,2,3,4};
int b[][]={{1,2,3,4},{1,2,3,4},{1,2,3,4}};
int c[][][]={{{1,2,3,4},{1,2,3,4},{1,2,3,4}},{{1,2,3,4},{1,2,3,4},{1,2,3,4}}};
上列三個陣列長度分別為何呢?
public class Ch41
{
public static void main(String args[])
{
int a[]={1,2,3,4};
int b[][]={{1,2,3,4},{1,2,3,4},{1,2,3,4}};
int c[][][]={{{1,2,3,4},{1,2,3,4},{1,2,3,4}},{{1,2,3,4},{1,2,3,4},{1,2,3,4}}};
System.out.println(a.length); //4
System.out.println(b.length); //3
System.out.println(c.length); //2
}
}
