How to use a string in the .setFireTicks() function

Hello,
I am making a private plugin for my server, and i want to be able to troll a friend of mine. I want it so that whenever he tries to run a command, it sets him on fire, but whenever i try to use a string, whether it be through a function, a variable or just putting the string next to it, I get this 'The method setFireTicks(int) is undefined for the type String'

Code:java

 }else if(command.equalsIgnoreCase("rl") && sender.equals("Saint_Goat")){
 
Player target = Bukkit.getServer().getPlayer("Saint_Goat");
target.setFireTicks(3000);
}

any help appreciated

 

Use

Code:java

int ticks = Integer.parseInt(YourStringHere);
RandomLoc.getGoat().setFireTicks(ticks);

This convert your string into integer value (this have a NumericFormatException if you put a no numeric character)

 

Set fire ticks only takes an int as a parameter all it does is set the ticks a fire is burning for.
