in java, I need help filling out these methods

public class ElectionManager $\{$

public static boolean containsCandidate$($String$[][]$ candidates, int

numCandidates, String name, String party$)\{$

if $($name$.$length$()==0)\{$

return false;

$\}$

return true;

$\}$

public static int addCandidate$($String$[][]$ candidates, int

numCandidates, String name, String party, int numVotes$)\{$

return numCandidates;

$\}$

public static int dropCandidate$($String$[][]$ candidates, int

numCandidates, String name, String party$)\{$

return numCandidates;

$\}$

public static String findWinner$($String$[][]$ candidates, int

numCandidates$)\{$

return null;

$\}$

public static String findLowestPollingCandidate$($String$[][]$ candidates,

int numCandidates$)\{$

return null;

$\}$

$\}$

Our test string of canidates is:

String$[][]$ candidateList $=\{$

$\{"$Slowpoke$",$ "Water", $"3"\},$

$\{"$Squirtle$",$ "Water", $"97"\},$

$\{"$Wooper$",$ "Water", $"300"\},$

null, null, null$\}$;
