why do we need peek() when we have get() in linked list?

Question

why do we need peek() when we have get() in linked list?.while I am studying the linked list I have this doubt. what is difference between them?

Answer 1

get() requires an index to access an element, peek() doesn't. As you can read in the comments the peek() also comes from the Queue-Interface.

Simple said the peek() internally ( see implementation )

• calls get(0) if the list is not empty
• returns null if the list is empty

The get(0) itself doesn't return null , it throws an java.lang.IndexOutOfBoundsException instead.

Answer 2

LinkedList - Get vs Linked List - Peek

Take a look at the return values and thrown errors.
