Hello: I have this code:

Code:

    package com.webs.playsoulcraft.plazmotech.java.MineRegen;
   
    import java.util.logging.Logger;

    public class Main extends JavaPlugin{
        String pmrgenable = "no";

        @Override
        public void onEnable() {
            this.log.info("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~");
            this.log.info("Plaz's Mine Regen is now enabled!");

            return false;
        }
       
        public void onPlayerInteract(PlayerInteractEvent event) {
            final Action action = event.getAction();
            final Location blockLocation = event.getClickedBlock().getLocation();

                while(true) {
                    try {
                        Thread.sleep(1000*60);
                        Location bloc = null;
                        log.info("Mine regenerated!");
                        for(double i=l1.getX(); i == l2.getX(); i++){

                                    bloc.setZ(k);
                                    World w = bloc.getWorld();
                                    Block b = w.getBlockAt(bloc);
                                    if(r <= 5){
                                        b.setTypeId(56);
                                    }
                                    if(r <= 10 && r > 5){
                                        b.setTypeId(14);
                                    }
                                    if(r <= 25 && r > 10){
                                        b.setTypeId(15);
                                    }
                                    if(r <= 45 && r > 25){
                                        b.setTypeId(16);
                                    }
                                    if(r > 45){
                                        b.setTypeId(1);
                                    }
                                }
                            }
                        }
                       
                       
                    } catch (InterruptedException ie) {
                        log.info("Error!");
                    }
                }
            }
        };
        t.start();
    }

The important bit is the Thread t. Why can't I start it using t.start();? It gives me the error: Syntax error on token "start", Identifier expected after this token Please help!

 

You can't put statements like that inside a class, they need to be in a method.

Edit: Also, you should really be using the scheduler for this, not a thread.
