just a recommendation: perhaps you might want to put the number 100 as a named constant to avoid magic numbers! it will also be easier for you to find & change this number in the future if everything is put on top :]

note that plural form should be used on names representing a collection of objects. might want to change this to a different name instead to for better readability - perhaps something like commandParts/commandTypes or other appropriate names!

switch statement should be in the following form:
switch (condition) {
case ABC:
statements;
// Fallthrough
case DEF:
statements;
break;
case XYZ:
statements;
break;
default:
statements;
break;
}

additionally, might want to consider moving & refactoring the different operations to different methods (e.g. listTasks(), markTask()) so that everything is not under the main method! try to avoid long methods :]
