java - Issue with arrays -


i have issue array while developing bukkit plugin. why doesn't work? supposed check whether player has placed block. keeps on saying "diamonds!!" ingame.

@eventhandler public void onplaceofdiamond(blockplaceevent e){     player player = e.getplayer();     string storage[] = new string[100];     int = 0;      if(e.getblock().gettype() == material.diamond_block){         if(arrays.aslist(storage).contains(player.getname())){             player.sendmessage(chatcolor.blue + "you on list");         }else{             player.sendmessage(chatcolor.blue + "diamonds!!");             storage[i] = player.getname();             i++;         }     } }

it's because creating new storage array every time player places block:

@eventhandler public void onplaceofdiamond(blockplaceevent e){     player player = e.getplayer();     string storage[] = new string[100];

so you'll never have complete list of players. fix this, should declare array outside of method:

string storage[] = new string[100];  @eventhandler public void onplaceofdiamond(blockplaceevent e) {     player player = e.getplayer();     int = 0;      if(e.getblock().gettype() == material.diamond_block){         if(arrays.aslist(storage).contains(player.getname())){             player.sendmessage(chatcolor.blue + "you on list");         }         else{             player.sendmessage(chatcolor.blue + "diamonds!!");             storage[i] = player.getname();             i++;         }     } }
