/* 謝宇哲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 {

    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*/}
