About output
Inside of the TestEmployee class, after making changes in line of println() method. It shows red line below manager getDetails . My output shows error.Syntax error on token "manager",delete this tokenThe method get details() is undefined for the type StringAt TestEmployee.main(TestEmployee.java:10)As shown in other tutorial videos, I think something is missing in that line or may be not visible in that video at that time.
