    • parseInteger

      public static int parseInteger(String string, int defaultValue)
      Tries to parse an integer value from a string. If the provided string is an integer, the parsed int will be returned. Otherwise the provided default value is returned instead.
      Parameters:
      string - the string you want to parse.
      defaultValue - the default return value if the string could not be parsed.
      Returns:
      the parsed int value, or the provided default value if the string could not be parsed.

    • parseLong

      public static long parseLong(String string, long defaultValue)
      Tries to parse a long value from a string. If the provided string is an integer/long, the parsed long will be returned. Otherwise the provided default value is returned instead.
      Parameters:
      string - the string you want to parse.
      defaultValue - the default return value if the string could not be parsed.
      Returns:
      the parsed long value, or the provided default value if the string could not be parsed.

    • parseFloat

      public static float parseFloat(String string, float defaultValue)
      Tries to parse a float value from a string. If the provided string is a floating number, the parsed float will be returned. Otherwise the provided default value is returned instead.
      Parameters:
      string - the string you want to parse.
      defaultValue - the default return value if the string could not be parsed.
      Returns:
      the parsed float value, or the provided default value if the string could not be parsed.

    • parseDouble

      public static double parseDouble(String string, double defaultValue)
      Tries to parse a float value from a string. If the provided string is a floating number, the parsed float will be returned. Otherwise the provided default value is returned instead.
      Parameters:
      string - the string you want to parse.
      defaultValue - the default return value if the string could not be parsed.
      Returns:
      the parsed float value, or the provided default value if the string could not be parsed.

    • parseBoolean

      public static boolean parseBoolean(String string, boolean defaultValue)
      Tries to parse a boolean from a string. If the provided string is "true" or "false" (or "1" or "0"), the parsed boolean value will be returned. Otherwise the provided default value is returned instead.
      Parameters:
      string - the string you want to parse.
      defaultValue - the default return value if the string could not be parsed.
      Returns:
      the parsed boolean value, or the provided default value if the string could not be parsed.

    • isInteger

      public static boolean isInteger(String string)
      Determines whether or not the provided string represents an integer/long value (for example, it will return true for values like "0", "1", "-7", "42", but false for strings like "7.62", "Hello", "5+5" etc).
      Parameters:
      string - the string you want to check.
      Returns:
      true if the provided string represents an int value, false if not.

    • isNumeric

      public static boolean isNumeric(String string)
      Determines whether or not the provided string represents a numeric value (integer/long or float/double, for example, it will return true for values like "0", "1.426", "-100", "22.0", but false for strings like "3k", "Bonjour", "7*7" etc).
      Parameters:
      string - the string you want to check.
      Returns:
      true if the provided string represents a numeric value, false if not.

    • isHex

      public static boolean isHex(String string)
      Determines whether or not the provided string represents a hexadecimal (hex) value using a "0x" prefix (for example, it will return true for values like "0xFF", "0xaabbcc", "0x41AB", "0x0", but false for strings like "56", "#FFAA13", "0xZVKK").
      Parameters:
      string - the string you want to check.
      Returns:
      true if the provided string represents a hex value, false if not.

    • isBoolean

      public static boolean isBoolean(String string)
      Determines whether or not the provided string represents a boolean value (lower case, it will only return true for "true" or "false").
      Parameters:
      string - the string you want to check.
      Returns:
      true if the provided string equals "true" or "false", false if not.

    • combineStringArray

      public static String combineStringArray(String[] array, int start, int end, char delimiter)

    • firstCharToUpper

      public static String firstCharToUpper(String string)

    • firstCharToLower

      public static String firstCharToLower(String string)

    • removeAllNonWordCharacters

      public static String removeAllWhitespaces(String string)

    • removeAllLeadingWhitespaces

      public static String removeAllLeadingWhitespaces(String string)
      Removes all leading white spaces. e.g if you provide the string " Test", this function returns "Test". If you provide "Hello World", this function returns the unmodified "Hello World" string.
      Parameters:
      string - the string you want to remove the leading white spaces from.
      Returns:
      the new string which does not contain any leading white spaces.

      the individual lines as an array of strings.

    • getMd5

      public static String getMd5(String string)

      an MD5 hash.
