Question

class Tree {
void print () {System.out.println("Tree"); }
public static void main(String args[]) {
Tree[] a = new Tree[3];
a[0] new Tree();
a[1] new Banyan();
a[2] new Peepal();
for (int i=0; i<a.length; i++) {
((Tree) a[i]).print();
}

Tree

Banyan

Peepal

Answer 2

Answer:

we will get errors when we will try to compile and run this program.

Explanation:

• Tree[] a = new Tree[3];   this statement creates the array of Tree objects and there are 3 objects of type Tree.
• a[0] new Tree();    a[1] new Banyan();   a[2] new Peepal();  these three statements are not valid statements.
• There is no class named Banyan or Peepal; so we can't create & initialize their objects using constructor.
• There is a class called Tree and we can create & initialize actual Tree objects using constructor but the right syntax for that is a[0] =new Tree();
