About Delphi

About Java

Java is a high-level programming language developed by Sun Microsystems. It was originally designed for developing programs for set-top boxes and handheld devices, but later became a popular choice for creating web applications.

Palindrome Check Example: Delphi vs Java

Palindrome Check in Delphi

function IsPalindrome(const S: string): Boolean;
var
  CleanStr: string;
  I: Integer;
begin
  // Remove non-alphanumeric characters and convert to lowercase
  CleanStr := '';
  for I := 1 to Length(S) do
    if S[I].IsLetterOrDigit then
      CleanStr := CleanStr + S[I].ToLower;

  // Check if the string is equal to its reverse
  Result := CleanStr = ReverseString(CleanStr);
end;

// Example usage
WriteLn(IsPalindrome('A man, a plan, a canal: Panama'));  // True
WriteLn(IsPalindrome('race a car'));  // False

Palindrome Check in Java

public class PalindromeChecker {
    public static boolean isPalindrome(String str) {
        String cleanStr = str.toLowerCase().replaceAll("[^a-z0-9]", "");
        return cleanStr.equals(new StringBuilder(cleanStr).reverse().toString());
    }

    public static void main(String[] args) {
        System.out.println(isPalindrome("A man, a plan, a canal: Panama")); // true
        System.out.println(isPalindrome("race a car")); // false
    }
}

Bubble Sort Example: Delphi vs Java

Bubble Sort in Delphi

procedure BubbleSort(var Arr: array of Integer);
var
  I, J, Temp: Integer;
begin
  for I := High(Arr) downto Low(Arr) do
    for J := Low(Arr) to I - 1 do
      if Arr[J] > Arr[J + 1] then
      begin
        Temp := Arr[J];
        Arr[J] := Arr[J + 1];
        Arr[J + 1] := Temp;
      end;
end;

// Example usage
var
  Arr: array of Integer;
begin
  SetLength(Arr, 7);
  Arr[0] := 64; Arr[1] := 34; Arr[2] := 25; Arr[3] := 12;
  Arr[4] := 22; Arr[5] := 11; Arr[6] := 90;

  WriteLn('Original array:');
  PrintArray(Arr);

  BubbleSort(Arr);

  WriteLn('Sorted array:');
  PrintArray(Arr);
end;

Bubble Sort in Java

public class BubbleSort {
    public static void bubbleSort(int[] arr) {
        int n = arr.length;
        for (int i = 0; i < n; i++) {
            for (int j = 0; j < n - i - 1; j++) {
                if (arr[j] > arr[j + 1]) {
                    int temp = arr[j];
                    arr[j] = arr[j + 1];
                    arr[j + 1] = temp;
                }
            }
        }
    }

    public static void main(String[] args) {
        int[] arr = {64, 34, 25, 12, 22, 11, 90};
        bubbleSort(arr);
        System.out.println(Arrays.toString(arr));
    }
}
