    • 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.
      Parameter:
      string - the string you want to parse.
      defaultValue - the default return value if the string could not be parsed.
      Gibt zurück:
      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.
      Parameter:
      string - the string you want to parse.
      defaultValue - the default return value if the string could not be parsed.
      Gibt zurück:
      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.
      Parameter:
      string - the string you want to parse.
      defaultValue - the default return value if the string could not be parsed.
      Gibt zurück:
      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.
      Parameter:
      string - the string you want to parse.
      defaultValue - the default return value if the string could not be parsed.
      Gibt zurück:
      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.
      Parameter:
      string - the string you want to parse.
      defaultValue - the default return value if the string could not be parsed.
      Gibt zurück:
      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).
      Parameter:
      string - the string you want to check.
      Gibt zurück:
      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).
      Parameter:
      string - the string you want to check.
      Gibt zurück:
      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").
      Parameter:
      string - the string you want to check.
      Gibt zurück:
      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").
      Parameter:
      string - the string you want to check.
      Gibt zurück:
      true if the provided string equals "true" or "false", false if not.
