Consider refactoring the code to reduce the length in void main

else if should be placed on the same line as on 42

consider using multiple print statements to make the code more readable

ideal to refer to all instance parameters with the this keyword, e.g. this.isDone

good use of ternary statements, though brackets are not needed to evaluate them

can consider making the length of the task array a variable

Class/enum names must be nouns and written in PascalCase. So in your case, it should be InputParser instead.

avoid using magic literals in the code, consider storing it in a constant (static final)

good, but maybe this can be a constant at the class-level

this function is quite long (30+ LOC). consider abstracting out the code into multiple functions

the command types can perhaps be stored as constants or you could probably use enums to avoid the usage of magic literals.

this is 4 levels of nesting, it makes the code hard to read and debug if any problems arise. consider refactoring this to multiple methods.

avoid leaving in commented-out code. it can reduce readability
