You can take a look at this code that handles timing:

import java.util.*;
volatile int state=-1;
//Intervals in millis
long timings[]={2000, 3000, 5000};
//timer class used
Timer timers[]=new Timer[timings.length];
//A creates the timer task that switches to state i
TimerTask createTask(final int i) {
  return new TimerTask() {
    @Override void run() {
      //If you want additional code to be executed when the state gets switched to i do it here.
      state=i;
    }
  };
}
void setup() {
  //Creates the timers and sets them to be executed at the givens intervals.
  for (int i=0; i<timings.length; i++) {
    timers[i]=new Timer();
    timers[i].scheduleAtFixedRate(createTask(i), 
    /*Time until first execution*/ timings[i],
    /*Interval in wich execution is done*/ timings[i]);
  }
}
void draw() {
  println(state);
}

Also an option you might explore would be looking into the registerMethod method. Here would be a little example on one possible application:

public abstract class Task {
  public abstract void draw();
}
public class TaskA extends Task{
  public void draw() {
    println("Hi");
  }
}
public class TaskB  extends Task{
  public void draw() {
    println("Hello");
  }
}
Task ta=new TaskA();
Task tb=new TaskB();
void setup() {
  //The draw method of the Object ta is executed after the draw method of this sketch
  this.registerMethod("draw",ta);
}
//Any method where you do not want two threads executing the method at the same time should be declared synchronized
synchronized void swap(Task t1,Task t2){
  this.unregisterMethod("draw",t1);
  this.registerMethod("draw",t2);
}
void draw(){
  if(frameCount==300) swap(ta,tb);
}

I hope these examples help you!
