How to declare a dynamic object array in Java?

Question

I want to ask a question about Java. I have a user-defined object class, student, which have 2 data members, name and id. And in another class, I have to declare that object

Answer 1

Its not possible,we need to specify the size of array when declaring object array;

1. one way to declare object array

    student st[];
    st=new student[3];
   

2. second way

    student st[]=new student[5];
   

in both cases not any objects are created only the space is allocated for the array.

st=new student[1];

this will create a new object;
