```
public class DuplicateObjectException
extends ApplicationException
```
An DuplicateObjectException is thrown if an object was rejected because it is a duplicate. This typically happens if objects are registered (e.g. in a Map) and an object is already associated for the same key.

public DuplicateObjectException(Object object)
```
    The constructor.
    
    Parameters:
    
    object - is the object that was rejected because it is a duplicate.

public DuplicateObjectException(Object object,
                                Object key)
```
    The constructor.
    
    Parameters:
    
    object - is the object that was rejected because it is a duplicate.
    
    key - is the key the object could NOT be associated with because it already leads to another object.
  - DuplicateObjectException
```
public DuplicateObjectException(Object object,
                                Object key,

```
    The constructor.
    
    Parameters:
    
    object - is the object that was rejected because it is a duplicate.
    
    key - is the key the object could NOT be associated with because it already leads to another object.

```
    This method puts the given value into the given map using the given key.
    
    Type Parameters:
    
    KEY - is the generic type of the key.
    
    VALUE - is the generic type of the value.
    
    Parameters:
    
    map - is the Map.
    
    key - is the key.
    
    value - is the value to put.
    
    Throws:
    
    DuplicateObjectException - if the given map already contains a value for the given key that is NOT equal to the given value.
  - getCode
```
public String getCode()
```
    Description copied from class: ApplicationException
    
    This method gets the code that identifies the detailed type of this object. While UUID is unique per instance of a ApplicationException this code is a short and readable identifier representing the ApplicationException Class. The default implementation returns the simple name. However, the code should remain stable after refactoring (so at least after the rename the previous code should be returned as String literal). This code may be used as a compact identifier to reference the related problem or information as well as for automatic tests of error situations that should remain stable even if the message text gets improved or the locale is unknown.
    
    Overrides:
    
    getCode in class ApplicationException
    
    Returns:
    
    the error code.
