how do i create an array of objects

hello,
i have created an array or my own named Store. i want to create an array of objects using this class.
iv used
Store[] s=new Store[2];
then im assigning values to the elements using a for loop
for(int i=0;i<2;i++)
{ s[i].setXXX(parameter);}
but im gettin a null pointer exception here on s[i].setXXX line.
Please tell me how to correct this part. Where have i gone wrong.

You just declared Store[] s array object but did not initialized the s[1] & s[2] objects. You need initialize them before calling the set methods. How about modifying your for loop some thing similar to:


for(int i=0;i<2;i++)
{
s[i] = new Store(); // initializing
s[i].setXXX(parameter);
}

You've declared an array of Store objects called s, and instantiated the array with a length of 2...

Store[] s = new Store[2];

But there are no Store objects referenced in the array. Instead, s[0] and s[1] are both null, which results in the NullPointerException when you attempt to dereference them.

You need to assign references to Store instances. For example...

s[i] = new Store();
