What I want is to randomly select agents based on their parameters from Main. So, rather than selecting an agent by its index - agent.get(i) - I want to randomly select an agent by its properties.
I would love it if something like this is possible:
agent.get(randomWhere(agent, a -> a.age > 50 && a.health == "good" && ...));
I am aware that the randomWhere function will return the agent but, not its index. so is there a function that would do this directly?
The workaround I thought of is:
1- list all the agents using the filter function:
List agentslist = filter( agent, p -> p.p_gender == false && ...);
which would return something like :
[root.agent[1]( p_gender = false,...),root.agent[5]( p_gender = false,...),root.agent[17]( p_gender = false,...)]
2- I loop though the agentslist using Regex to get the index of each agent from what is between the [ ] in a new list. Based on this example this new list will have these values [1,5,17] .
3- Finally, I choose randomly from the new list and input its value in the agent.get(i) directly.
Is there a better way to do this?
Thanks in advance,
to get the index just use the getIndex() function.
int index=randomWhere(yourAgents,a->a.age>50 && a.health.equals("good")).getIndex();
agent.get(index);
Remember to use equals() when you compare strings... "==" is only used effectively for primitives.
