how to create an Object array and how to work with it

[zavrisky]

class test
{
void printLine()
{
System.out.println("Hello World"
}
}

class drive
{
public static void main(String args[])
{
test obTest[] = new test[10];

obTest[0].printLine();
}
}


My objective is to create an array of a class object and to work with it. The above one is a test code, and probably I am missing something as it is not working. Help me out someone.
I am a beginner, sorry for the dumb question.
and thanks in advance

With this line
test obTest[] = new test[10];
you have meade the declaration but the array is still empty you have to fill it with test-Objects
ex.
for(int i=0; i<obTest.length; i++)
obTest=new test();

//See below - arrays are initialized to nulls by JVM

class test
{
void printLine()
{
System.out.println(&quot;Hello World&quot;
}
}

class drive
{
public static void main(String args[])
{
test obTest[] = new test[10];
/*Next line added by me to create a non-null object reference, since the object array above is simply being created, but, since no constructor is being called, is initialized by the JVM to all &quot;nulls&quot;.*/
obTest[0] = new test();//First array element initialized
// by assigning to it the reference returned by
// the constructor call, 'new test()' .
obTest[0].printLine(); //This now works
//Also, let's setup a test object in the array's 10th pos.
obTest[9] = new test();
obTest[9].printLine(); // This prints another line.
// The other 8 array items are still null object refs,
// and cannot be used. The two in use refer to
// anonymous objects. The array has a name, but the
// objects represented by it do not have names.
