what is Ljava.lang.String;@

The method works if you provide an array. The output of

String[] helloWorld = {"Hello", "World"};
System.out.println(helloWorld);
System.out.println(Arrays.toString(helloWorld));

is

[Ljava.lang.String;@45a877
[Hello, World]

(the number after @ is almost always different)

Please tell us the return type of Employee.getSelectCancel()
