How to get values ​​from hashmap

My HashMap:

Code:java

package API.CustomEvents;
 
import org.bukkit.entity.Player;
import org.bukkit.event.Event;
import org.bukkit.event.HandlerList;
 
import java.util.HashMap;
 
public class MiniEventsJoinEvent extends Event {
    private static final HandlerList handlers = new HandlerList();
 
    Player player;
    String string;
    Integer newsize;
    Integer getTimeLeft;
    HashMap<String, String> players;
 
    public MiniEventsJoinEvent(Player player, String string, Integer newsize
            , Integer getTimeLeft, HashMap<String, String> players) {
        this.player = player;
        this.string = string;
        this.newsize = newsize;
        this.getTimeLeft = getTimeLeft;
        this.players = players;
    }
 
    /**
    * @return the name of the event.
    */
    public String getEventName() {
        return this.string;
    }
 
    /**
    * @return the player who joined the event.
    */
    public Player getPlayer() {
        return this.player;
    }
 
    /**
    * @return the number of players in the event.
    */
    public int getAmountOfPlayersInEvent() {
        return newsize;
    }
 
    /**
    * @return how long until the event auto stops.
    * (seconds)
    */
    public int getTimeLeft() {
        return getTimeLeft;
    }
 
    /**
    * @return the HashSet the contains all the player from any event.
    */
    public HashMap<String, String> getPlayersInEvent() {
        return players;
    }
 
    public HandlerList getHandlers() {
        return handlers;
    }
 
    public static HandlerList getHandlerList() {
        return handlers;
    }
}
 

How to get newsize ​​from hashmap
These doesnt work

1. MiniEventsJoinEvent.get("newsize");

 

You didn't give it a value. Where you create the HashMap add:

Code:java

 = new HashMap<>();

After you add this to the end of the line it should work.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

baugh70 check his constructor, he assigns it there.
StatywPlay MiniEventsJoinEvent.get("newsize"); isn't defined in the class. If you want the newsize variable, call getAmountOfPlayersInEvent()

 

New problem

Code:java

                        if (!plugin.getInfo().inevent.size() >= 5) {
                            plugin.send(player, "full-event");
                            return true;

Error: The operator ! is undefined for the argument type(s) int

File Info

Code:java

package Util.Methods;
 
import Mains.MiniEvents;
import org.bukkit.configuration.file.FileConfiguration;
import org.bukkit.entity.Player;
import org.bukkit.scoreboard.Scoreboard;
 
import java.util.HashMap;
import java.util.HashSet;
 
public class Info{
    public MiniEvents plugin;
 
 
    public Info(MiniEvents plugin) {
        this.plugin = plugin;
    }
    public boolean eventstarting = false;
    public boolean eventstarted = false;
    public boolean cancelled = false;
    public final HashSet<String> sbefore = new HashSet<>();
    public final HashSet<String> sblue = new HashSet<>();
    public final HashSet<String> sred = new HashSet<>();
    public final HashSet<String> sfire = new HashSet<>();
    public final HashMap<String, String> inevent = new HashMap<>();
    public final HashMap<String, Scoreboard> scoreboard = new HashMap<>();
 
    public int eventSize(){
        return inevent.size();
    }
    public String getEventName(){
        return plugin.getEventName();
 
    }
    public boolean eventStarting(){
        return eventstarting;
    }
    public boolean eventStarted(){
        return eventstarted;
    }
    public boolean inEvent(Player player){
        return inevent.containsKey(player.getName());
    }
    public String eventFormalEventName(String s){
        return plugin.getFormalName(s);
    }
    public int getTimeLeft(){
        return plugin.getTimerMain().getTimeLeft();
    }
    public FileConfiguration getPlayerFile(Player player){
        return plugin.playerFile(player.getName().toLowerCase());
    }
    public HashMap<String, String> getPlayersInEvent(){
        return inevent;
    }
    public boolean inSpectateMode(Player player){
        return plugin.getSpectateMode().inspec.contains(player.getName());
    }
}
 
 

 

StatywPlay why is that ! there in the first place... It seems logically incorrect regarding to the contents of the block that follows.

Moreover you should declare your fields private ;3 (with a public accessor if you need access anywhere else)
