Addressing the Error in Creating an Array of LinkedLists
In Java, it is not possible to create a generic array of LinkedLists directly. This is due to a limitation of the Java language known as "generics erasure." When compiling Java code, the compiler erases type information for generic types like LinkedList. As a result, the Java Virtual Machine (JVM) only sees raw types like LinkedList when executing the code.
Resolving the Issue
To resolve this issue, you can cast the type and make the declaration like this:
<code class="java">myMatrix = (LinkedList<IntegerNode>[]) new LinkedList<?>[numRows];</code>
By casting the array to a specific type, you are explicitly telling the compiler that you intend for it to be an array of LinkedLists containing IntegerNode objects. The wildcard character (?) in the declaration indicates that the specific type of elements within the LinkedList array is irrelevant, as long as they are objects of any type.
