Write the boolean method called "isPresent" below that accepts a String parameter called "name" and

returns true if the String "name" is present in a linked list of NameNodes, and false if it is not present. If

the String parameter is empty or null, return false. Assume NameNode exists as shown below, and a

variable called "first" refers to the start of the linked list: $[12$ pts$]$

public boolean isPresent $($String name$)\{$public String name;public NameNode$($String name$)$ this.name $=$ name;$\}$
