w3schools學習:陣列array,方法length,迴圈for-each

/*江紫恩2022.11.7.w3schools,陣列array,陣列長度方法length,陣列是在型態後面加[] corner brachet */
public class Main {
  public static void main(String[] args) {
    String[] hey = {"富豪", "寶馬", "福特", "馬自達","撈屎來食","瀕死"};
    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);
    }
  }
}
