java - Generate a random interger within a case: in a Loop() -

i have functioning script game, uses java client.

i trying generate random number upon loop each time case: comes up.

public int onloop() throws interruptedexception {      switch (getstate()) {          case attack:             entity seagull = npcs.closest("seagull");                 if(seagull.exists())  {                 seagull.interact("attack");                 sleep(random(1500, 2000));             }                 break;         case attacking:              int decide = random(1, 3);                 if(myplayer().isanimating()) {                     getskills().hoverskill(skill.strength);                     log("checking stats...");                     sleep(random(1000, 9000));                 }else if(decide == 3) {                     getmouse().moveoutsidescreen();                     sleep(random(5000, 30000));                     log("afking");                 }                 break; 

here using generate random int:

int decide = random(1, 3); 

and trying pull number with:

else if(decide == 3) { 

but have had no luck!

function numbers(objid) {    var rand_inta = math.floor(math.random()*5); // first number    document.getelementbyid(objid).innerhtml=(rand_inta); //print second box  }
