    Default unchecked or unsafe operations ERROR

    This is the line of code generating the "unchecked or unsafe operations" error. There is an arrow that points to "new". How do I get rid of this error so I can compile my code?

    public static ArrayList<String>[] sbins = new ArrayList<String>[10];

    Default Re: unchecked or unsafe operations ERROR

    Note: HW4c.java uses unchecked or unsafe operations.
    Note: Recompile with -Xlint:unchecked for details.

    so when I compile with -Xlint the program runs fine but there are like 10 warnings.

    warning: [unchecked] unchecked call to add<E> as a member of the raw type java.util.ArrayList
    sbins[7].add(s)

    and there is an arrow that points to the "(" after add.
