how do i loop an if statement on a timer in java?

so im trying to make a minecraft plugin that sends a string of text in chat on random intervals. now im trying to make it start from line 1 every 5 minutes. i just dont know how to do this Ps: im new to java.

Random rand = new Random();
int n = rand.nextInt(3);

if (n == 1) {
    Bukkit.broadcastMessage("yeet");
}

>Solution :

A quick search should lead you to this:
https://bukkit.org/threads/creating-a-loop.119088/
https://www.codegrepper.com/code-examples/java/bukkit+repeating+task+every+minute+spigot

The code, without testing it:

Bukkit.getScheduler().scheduleSyncRepeatingTask(plugin, new Runnable() {
    @Override
    public void run() {
        Bukkit.broadcastMessage("This message is shown immediately and then repeated every second");
    }
}, 0L, 20L); //0 Tick initial delay, 20 Tick (1 Second) between repeats

It seems like in Minecraft, 20 Ticks equals to one second. So you should calculate 20 x 60 x 5 to get the amount of ticks needed for 5 minutes.

Try 6000.

I also recommend to you to read the Javadoc of the Bukkit project.

https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/scheduler/BukkitScheduler.html#scheduleSyncRepeatingTask(org.bukkit.plugin.Plugin,org.bukkit.scheduler.BukkitRunnable,long,long)

This should lead you to the current function that is used.
