- Method Detail
  - groupCount
```
public int groupCount()
```
    Returns the number of captured groups of this match. Any non-negative integer smaller than the value returned by this method is a valid group index for this match.
    
    Returns:
    
    The number of captured groups.
  - group
```
public java.lang.String group(int idx)
```
    Returns the input subsequence captured by the given group by this match. Groups are indexed from left to right, starting at zero. Note that some groups may match an empty string, in which case this method returns the empty string. This method never returns null.
    
    Parameters:
    
    idx - The index of the group to return.
    
    Returns:
    
    The (possibly empty) substring captured by the group during matching, never null.
    
    Throws:
    
    java.lang.IndexOutOfBoundsException - If there is no group in the match with the given index.
