How to use Ternary Operator in JSP

I have a query with regards to using Ternary Operator in JSP. The below mentioned code uses if else statement which works fine.

<%
                if ("Y".equals(TestPerformed)) {%>
            Test Performed <input type="checkbox" id="TestPerformed<%=RowCount%>" name="TestPerformed" value="Y" checked>
            <%} else {%>
            Test Performed <input type="checkbox" id="TestPerformed<%=RowCount%>" name="TestPerformed" >
            <%}%>
            <input type="text" id="HiddenTestPerformed<%=RowCount%>" name="TestPerformed" value="<%=TestPerformed%>"/>
            <script>
                $(function () {
                    $("#TestPerformed<%=RowCount%>").change(function () {
                        $("#HiddenTestPerformed<%=RowCount%>").val(($(this).is(':checked')) ? "Y" : "N");
                    });
                });
            </script>

But When I use the Ternary Operator it gives me a compile time error stating not a statement.

Test Performed <input type="checkbox" id="TestPerformed<%=RowCount%>" name="TestPerformed" value="Y" <%"Y".equals(TestPerformed) ? "checked":"";%>>
            <input type="text" id="HiddenTestPerformed<%=RowCount%>" name="TestPerformed" value="<%=TestPerformed%>"/>
            <script>
                $(function () {
                    $("#TestPerformed<%=RowCount%>").change(function () {
                        $("#HiddenTestPerformed<%=RowCount%>").val(($(this).is(':checked')) ? "Y" : "N");
                    });
                });
            </script>

The Above code basically checks if the TestPerformed is Y or N. If its Y then the Checkbox will be checked or else it will be unchecked. The Jquery is used to change the value of the HiddenTestPerformed input to Y or N.

Kindly help me out as in How do I use this Ternary Operator to fulfill this requirement.

Thanks in Advance.

You are just missing an equals in the scriplet, also some how you need to insert in (brackets) the whole expression and you dont end with a ;

Finally <%= ( <expression> ? <then_String> : <else_String> ) %>

<input type="checkbox" id="TestPerformed<%=RowCount%>" name="TestPerformed" value="Y" <%=("Y".equals(TestPerformed) ? "checked":"")%> >
