Creating Objects without using the new keyword?

Question

This part of the code Iterator<String> it = animals.iterator();
I do not understand this part how can you use
animals.iterrator without the new keyword...is it calling a constructor here without the new keyword?

because I read from using the new keyword this prompts the IDE to create a space on the Heap for the object

Answer 1

This statement is just like
String f=intF.toString();//intF is an int variable

Similarly here you are creating a member of Iterator class named it,and using iterator method of animals object(List object).
