「陣列(Array)」
,按序排列的同類資料元素的
集合
。
1.
索引值是從0
開始計數
2.索引值
不可超出陣列的範圍
3.取陣列最後一個值=陣列長度-1
分別運用四種不同的陣列宣告方式, 完成參考執行畫面.

public static void main(String args[])
{
String a[]={"春","夏","秋","冬"};
String b[]={"甲","乙","丙","丁"};
System.out.print("陣列a: ");
for(int i=0; i<4; i++)
System.out.print(a[i]+" ");
System.out.println();
System.out.print("陣列b: ");
for(int i=0; i<4; i++)
System.out.print(b[i]+" ");
System.out.println();
int c[]={1,2,3,4};
//string d[4]; -> c++宣告長度為4的空陣列
String d[]=new String[4]; //宣告長度為4的空陣列
d[0]="A";
d[1]="B";
d[2]="C";
d[3]="D";
//foreach
//for(陣列型態 變數:陣列(來源))
