陣列 (一)

本帖最後由鄭繼威於 2022-12-10 10:20 編輯

「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 class Ch34
{
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))
System.out.print("陣列c: ");
for(int i:c)
System.out.print(i+" ");
System.out.println();
System.out.print("陣列d: ");
for(String sa:d)
System.out.print(sa+" ");
System.out.println();
}
