Perhaps you try using camelcase when naming variables. Eg. listOfTasks

Perhaps you could name this class as "Task" (singular) instead as it refers to one task

Good job for using a verb to name this method

In general, the code is quite clear, however, there is a lot of potential for clearer and more concise code.

Since you abstracted the [greet_user()] function, it may be better if you maintain Single Level of Abstraction Principle (SLAP), and also extract this portion as a separate function

It may be better to avoid using a magic number (100) and instead define it at the top of the file as MAX_NUMBER_OF_TASKS

+                }


It may be clearer to extract these parts as separate functions to avoid nesting loops.

Overall good effort in implementation.More work on SLAP with shorter methods, and classes will be helpful in future iP levels and tP.

Switch-case should not have different indentations.

Try keeping your main method short and have a parser to deal with interpreting user commands instead

+                case "event":


Perhaps consider using constants instead of strings, for example, COMMAND_EVENT instead of "event"

+                    Integer m_index = Integer.valueOf(command[1]);


m_index, u_index etc. might be easy for the original developer to understand but not for someone else reading it or another person taking over. Consider using clearer naming in this case.

Consider other data structures, apart from a fixed size array, to make your product more scalable, especially since we are already approaching recess week :)

Avoid using constructor names of other classes as method name. It can be confusing and potential source of bug. Also, consider separate classes for adding new tasks.
