`static boolean`	`isEmpty(String str)`
`static boolean`	`isFloatOnly(String str)` Ensures that the string is composed of only floating point numbers (digits [0-9] and maybe a "."), with optional leading/trailing blanks.
`static boolean`	`isIntegerOnly(String str)` Ensures that the string is composed of only an digits [0-9] with optional leading/trailing blanks.
`static boolean`	`isNotAllowed(String str, String unallowedChars)` Returns `true` if the specified string has no unallowed characters.

  - isIntegerOnly
```
public static boolean isIntegerOnly(String str)
```
    Ensures that the string is composed of only an digits [0-9] with optional leading/trailing blanks. (floating point/real numbers are not allowed because they contain a ".")
  - isFloatOnly
```
public static boolean isFloatOnly(String str)
