[Java] Окружения элемента в массиве Опции

[Merhaba]

Утро Доброе!
Помогите Пожалуйста переписать программу с Pascal на Java:

function Min(a,b: integer): integer;
begin
  if a<b then Min:= a else Min:= b
end;

function Max(a,b: integer): integer;
begin
  if a>b then Max:= a else Max:= b
end;


const
  n= 30;
  m= 20;

var
  a: array [1..n,1..m] of integer;
  i,j,k,l,p,q: integer;
  Ok: boolean;

begin
  Randomize;
  for i:=1 to n do for j:=1 to m do a[i,j]:= Random(100);
  for i:=1 to n do begin
    for j:=1 to m do Write(a[i,j]:3);
    WriteLn
  end;

  l:=0;
  for i:=3 to n-2 do for j:=3 to m-2 do begin
    Ok:= true;
    k:= 1;
    for p:= Max(i-k,1) to Min(i+k,n) do
      for q:= Max(j-k,1) to Min(j+k,m) do
        if (Abs(i-p)=k) or (Abs(j-q)=k) then Ok:= Ok and (a[i,j]>a[p,q]);
    k:= 2;
    for p:= Max(i-k,1) to Min(i+k,n) do
      for q:= Max(j-k,1) to Min(j+k,m) do
        if (Abs(i-p)=k) or (Abs(j-q)=k) then Ok:= Ok and (a[i,j]<a[p,q]);
    if Ok then Inc(l)
  end;

  WriteLn('found ',l,' of wanted elements');
  ReadLn
end.
