黃柏諺w3schools陳列array,方法迴圈for each
/* 黃柏諺2022.11.7.w3schools,陣列array,陣列長度方法length,陣列是在型態後面加[] corner bracket */
public class Main {
public static void main(String[] args) {
String[] hey = {"富豪", "寶馬", "福特", "馬自達", "勞斯萊斯","賓士"};
System.out.println(hey.length);
/*方法,函數, length陣列長度*/
/*迴圈輸出陣列hey*/
for (int i = 0; i < 5; i++){
System.out.println(hey[i]);
}
for ( String i: hey) {/*使用for-each迴圈,將each屬於hey陣列的元素*/}
System.out.println(i);
}
}
