I want to print an array of members to choose from and an array of books.. I have double checked many times, but both seem identical yet only 'bookarray' is printing.. public static Person[] createArray1() { Person[] personarray = new Person [5]; personarray[0] = new Person ("John Smith", 67, false, 1485); personarray[1] = new Person ("Joe Bailey", 58, false, 2003); personarray[2] = new Person ("Barbara Jones", 76, false, 9191); personarray[3] = new Person ("Felix Anderson", 36, false, 1974); personarray[4] = new Person ("Sarah Watson", 27, false, 1996); return personarray; } public static void printPersons (Person[] personarray) { for (int counter = 0; counter > personarray.length; counter++) { System.out.println("Test2"); System.out.println(counter + "." + personarray[counter].getString2()); } } public static void choosePerson(Select select) { Person[] listOfPeople = Service.createArray1(); System.out.println("Test1"); Service.printPersons(listOfPeople); } public static Book[] createArray() { Book[] bookarray = new Book[3]; // book title, isbn number, onloan = false.. passed in from Book object bookarray[0] = new Book ("The Lion, the Witch and the Wardbrobe", 80312, false); bookarray[1] = new Book ("Great Expectations", 4232, false); bookarray[2] = new Book ("The Lord of the Rings", 2131, false); return bookarray; } public static void printBooks(Book[] bookarray) { for (int counter = 0; counter < bookarray.length; counter++) { System.out.println(counter + "." + bookarray[counter].getString()); } } public static void orderBooks(Select select) { Book[] listOfBooks = Service.createArray(); Service.printBooks(listOfBooks); }What I have tried:"Test 1" In choosePerson is printing but "Test 2" in printPersons does not..推荐答案 for循环条件不同 这篇关于这两个方法都与我相同，但只有一个有效。的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
