String and Int Error?

The whole source code:

Code:

package net.nubpro.project.plugin.hp;

import java.util.logging.Logger;
import org.bukkit.command.Command;
import org.bukkit.command.CommandSender;
import org.bukkit.entity.Player;
import org.bukkit.plugin.java.JavaPlugin;

public class Hp extends JavaPlugin{
    private Player player;
    private static final Logger log = Logger.getLogger("Minecraft");

    public void onDisable() { log.info("[Health]Plugin had been disabled");
    }

    public void onEnable() { log.info("[Health]Plugin had been enabled");
    }
    public boolean onCommand(CommandSender sender, Command cmd, String cmdLabel, String[] args) {
        int health = player.getHealth();
        if ((sender instanceof Player)){
        if (cmd.getName().equalsIgnoreCase("hp"))
        {
        sender.sendMessage(health);
        }
        return false;
    }
        return false;
        }
}

A error occurs when I used "int"!
See below:

Code:

int health = player.getHealth();

A error occurs when using "int"
It keep telling me to change "int" to string due sender.sendMessage(health); cannot support int

Code:

        int health = player.getHealth();
        if ((sender instanceof Player)){
        if (cmd.getName().equalsIgnoreCase("hp"))
        {
        sender.sendMessage(health);

So I decide to change to string but getHealth(); doesnt support string

Code:

String health = player.getHealth();

It's making me MAD!
Is there anyway to fix this?

 

String health = player.getHealth().toString();

This is like very basic stuff, you should know this O_O.

 

lol not working.
-.-''

 

int doesn't have a toString method inherited from a superclass. It's a primitive data type. If you want to cast it as a string (but retain its use as an int) cast it as Integer.

Code:

Integer health = player.getHealth();
sender.sendMessage(health.toString());

alternatively:
int health = player.getHealth();
sender.sendMessage("" + health);

 

What does Integer health means?

 

Integer is a type (just like int) that stores data, it just wraps the int in a class with some methods to utilize the data in more than just one way (ie as an int)

the expression:

Code:

Integer health = player.getHealth();

Means (simply) to create a variable named "health" of type "Integer," and assign it the value returned by "player.getHealth()"

java.lang.Integer

 

Thanks it works!

 

@nubpro This seems to work for me:

Code:

public boolean onCommand(CommandSender sender, Command cmd, String cmdLabel, String[] args){
					
	if (cmd.getName().equalsIgnoreCase("hp")){
		if (sender instanceof Player){
			Player player = (Player) sender;
			int health = player.getHealth();
			player.sendMessage(String.valueOf(health));
			return true;
		}
	}
	return false;
}

EDIT: Nevermind, you figured it out.

 

I know there some problems with the return statements but I already figured out. ><

 

@nubpro I meant the "player.sendMessage(String.valueOf(health));" part... mainly.
