这两个方法都与我相同，但只有一个有效。 [英] Both of these series of methods seem identical to me, but only one works..
问题描述
我想要打印一系列成员供选择和一系列书籍..我已经多次检查过，但两者看起来完全相同但只有'bookarray'正在打印..
< br $>
public static Person [] createArray1（）
{
Person [ ] personarray = new Person [5];
personarray [0] =新人（John Smith，67岁，假，1485）;
personarray [1] =新人（Joe Bailey，58，false，2003）;
personarray [2] =新人（Barbara Jones，76，false，9191） ;
personarray [3] =新人（Felix Anderson，36岁，假，1974年）;
personarray [4] =新人（Sarah Watson， 27，false，1996）;
返回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（选择选择）
{
Person [] listOfPeople = Service.createArray1（）;
System.out.println（Test1）;
Service.printPersons（listOfPeople）;
}
public static Book [] createArray（）
{
Book [] bookarray = new Book [ 3];
//书名，isbn号，onloan = false ..从Book对象传入
bookarray [0] =新书（The Lion，the Witch and the Wardbrobe，80312，false）;
bookarray [1] =新书（Great Expectations，4232，false）;
bookarray [2] =新书（指环王，2131，假）;
返回bookarray;
}
public static void printBooks（Book [] bookarray）
{
for（int counter = 0 ; counter< bookarray.length; counter ++）
{
System.out.println（counter +。+ bookarray [counter] .getString（））; < br $>
}
}
public static void orderBooks（Select select）
{
预订[] listOfBooks = Service.createArray（）;
Service.printBooks（listOfBooks）;
}
我尝试了什么：
测试1在choosePerson正在打印，但printPersons中的测试2没有..
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..
