Is this valid Syntax to create character linklist?

Question

LinkedList<char> PC=new LinkedList<char>();

getting this error message when tried to run.

Solution.java:5: error: unexpected type
    LinkedList<char> PC=new LinkedList<char>();    
           ^
   required: reference
   found:    char

Can anyone explain why we can create the link list of arrays, object, and string but not of character?

This line seems to be OK. Most probably the error is in the line before. You should include in your post a few more lines of code. — Little Santi, Jan 24 '18 at 07:57

Array is an object, when char is a primitive type. As generics support only non-primitive types, you can create LinkedList<Character> and autoboxing will take care of packing chars into Character class.
