Connection:

Defines a connection between nodes (simplified with a string e.g "a"). Connection consists "from" and "to".

Task:

Defines a collection of connections.

"apply" method:

Using "apply" method, you can create inter-connection between existing connections. the connection between the same "from" and "to" should not be possible. e.g:

var task = new Task()
task.apply("1",Arrays.asList("1"))

should not create any connections. In other word task.getConnections() should be empty.

Example

var task = new Task()
task.apply("1",Arrays.asList("2", "3"))

would make the task has the following connections:

• connection between "1" and "2"
• connection between "1" and "3"
• connection between "2" and "1"
• connection between "2" and "3"
• connection between "3" and "1"
• connection between "3" and "2"

another call of apply method, e.g:

task.apply("4",Arrays.asList("1"))

would make the task having an updated connections:

• connection between "1" and "2"
• connection between "1" and "3"
• connection between "1" and "4"
• connection between "2" and "1"
• connection between "2" and "3"
• connection between "2" and "4"
• connection between "3" and "1"
• connection between "3" and "2"
• connection between "3" and "4"
• connection between "4" and "1"
• connection between "4" and "2"
• connection between "4" and "3"

be advised that calling task.apply("1",Arrays.asList("4")) and task.apply("4",Arrays.asList("1")) would result the same

You are allowed to create new classes, methods, enums or anything that would help you achieve your goal.
