陳姵蓁程式設計Java陣列array長度

w3schools陣列array宣告:型態[ ]方括號corner brackets
//陳姵蓁,2022/11/10,
public class Main {
  public static void main(String[] args) {
    String[] cars = {"富豪", "寶馬", "福特", "馬自達","老師來屎"};
    int j;                  /* 宣告位元數 j */
    j = cars.length;        /* 給定 j = 陣列 cars.長度 */
    System.out.println("陣列長度:"+ j );/* 方法印出來print */
    for (int i = 0; i < j; i++) {
      System.out.println(cars[i]);
    } 
    System.out.println("以下使用for-each迴圈輸出");
      for ( String i: cars) { /*將每一個cars陣列的項目items輸出*/
    System.out.println( i );
    } 
  }
