Passing Array of objects to a different class

Any ideas how I can use an array of objects that I have created in one class, in another class?

Sounds really simple but is giving me major problems.

Hi,

How about making an accessor method ?

Pass the array of objects from the first class to the constructor of the second class?

You can just use an instance of the class to access its array.
Consider this.

class1.java
------------
public class class1
{
public String firstName;
public String lastName;

class1(){};

class1(String firstName, String lastName)
{
this.firstName = firstName;
this.lastName = lastName;
}
}

class2.java (Create an array c1array of class1 objects)
--------------
public class class2
{
public class1 c1 = new class1("Amit", "Saini");
public class1 c2 = new class1("Rohit", "Saini");
public class1 c1array[] = {c1,c2}; //array of class1's objects
}

class3.java (Use the array created in class2)
-------------
public class class3
{
public static void main(String args[])
{
class2 c2 = new class2();
for (int i=0; i<c2.c1array.length; ++i)
{
System.out.println(c2.c1array[i].firstName + " " + c2.c1array[i].lastName);
}
}
}

OUTPUT
----------
C:\eclipse\workspace\helloworld>java class3

Even though your approach works, one should try to
