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));

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

(the number after @ is almost always different)

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

Ljava.lang.String;@ is returned where you used string arrays as strings. Employee.getSelectCancel() does not seem to return a String[]
