Is it possible to create a method returning a LinkedList and what would be the correct syntax ?
public LinkedList static void NewtonRaphson1() {
return linkedlist;
}
swap the static
and the return type
and remove the void
:
public static LinkedList<String> NewtonRaphson1() {
return new LinkedList<String>();
}
you have defined a wrong syntax.
Edit: As Tunaki mentioned it is better to use generic and declare the type of data that is in your list:
LinkedList<String>
LinkedList<Integer>
LinkedList<Float>
LinkedList<MyObjectClass>
otherwise you get a warning from your IDE
"LinkedList is a raw type. References to generic type LinkedList should be parameterized"
the great benefit of that is:
- Stronger type check during compile time
- you dont need casting.
omit the "void", a void method return nothing ...
public static LinkedList NewtonRaphson1() {
return linkedlist;
}
