How to print every array element?

Question

I have an array contains Employee object.

How do I print every element of the array?

I can only get it to print the last input.

/*This is Employees class
  toString accepts lastname, firstname, payrate, workhour, grosspay, tax, netpay, and return a string */
public void display(Employee a[])
    {
        for (int i=0; i<max; i++)
        {
            System.out.println(a[i].toString());
        }
     }

// main
        for (int a=0; a<max;a++)
        {
            list[a]=emps.getinfo(emp);
        }
        emps.display(list);

//Employee class
//  I am assuming there is something wrong with these two methods in my Employee class. 
public Employee(Employee e)
        {
            lastname=e.lastname;
            firstname=e.firstname;
        }
// Argument will be lastname, firstname, workhour, payrate, grosspay, tax and net.
public String toString()
        {
            return String.format("format", argument);
        }

I don't see it in the code you posted. Also, please post the Employee class. — Eran

I post the Employee class. As for the properties of the Employee instances, are you asking for the constructors of Employee? — Kai

Please post complete code. Including the instance variables of Employee class, including the actual body of getInfo. — Eran

The answer to your question regardless of code context:

Integer[] integers = {1, 2, 3};
System.out.println(Arrays.toString(integers));

looks like problem in

list[a]=emps.getinfo(emp);

most likely emp remains the same during your loop, so you get the same result. Your link does not provide any info, unfortunately.

I would suggest you write your array as List for more generic use of the object. it's a better practice this way, and now you can rock-n-roll with it like this:

List<String> items = new ArrayList<>();
items.add("A");
items.add("B");
items.add("C");
items.add("D");
items.add("E");

//lambda
//Output : A,B,C,D,E
items.forEach(item->System.out.println(item));

//Output : C
items.forEach(item->{
    if("C".equals(item)){
        System.out.println(item);
    }
});

//method reference
//Output : A,B,C,D,E
items.forEach(System.out::println);

//Stream and filter
//Output : B
items.stream()
    .filter(s->s.contains("B"))
    .forEach(System.out::println);
