    Parameters:
    
    data - the data to be split
    
    defAcRt - the default accuracy rate for data
    
    cl - the class label to be predicted
    
    Returns:
    
    the array of data after split
  - covers
```
public boolean covers(Instance inst)
```
    Whether the instance is covered by this antecedent
    
    Specified by:
    
    covers in class JRip.Antd
    
    Parameters:
    
    inst - the instance in question
    
    Returns:
    
    the boolean value indicating whether the instance is covered by this antecedent
  - toString
```
public java.lang.String toString()
```
    Prints this antecedent
    
    Specified by:
