  - join
```
public DataFrame join(DataFrame df)
```
    Description copied from interface: DataFrame
    
    Perform a one-to-one inner join on this (left) dataframe with the specified (right) dataframe by their key columns. The resulting dataframe will have a key column which is the intersection of the left and right key columns.
    If the left dataframe has N columns and the right has M columns then the resulting dataframe will have N + M - 1 columns, starting with all N columns from the left dataframe, followed by the columns from the right dataframe excluding the right key column. If the right dataframe has any column names in common with the left, the duplicate right column names will have a suffix appended to them in the result.
    If the left dataframe has S rows and the right has T rows then this join operation will use O(S + T) space and time. The space overhead is approximately S + T bits. The result will contain at most min(S, T) rows, and will be empty if the two key columns do not have any elements in common.
    
    Specified by:

    Parameters:
    
    df - - the right dataframe to be joined with this left one

    Perform a one-to-many inner join on this (left) dataframe with the specified (right) dataframe using the key column from the left dataframe. Elements from the specified column in the right dataframe will be matched against the key column using a binary search.
    If the left dataframe has N columns and the right has M columns then the resulting dataframe will have N + M - 1 columns, starting with all N columns from the left dataframe, followed by the columns from the right dataframe excluding the specified non-index column. If the right dataframe has any column names in common with the left, the duplicate right column names will have a suffix appended to them in the result.
    If the left dataframe has S rows and the right has T rows then this join operation will use O(T) space and run in O(T*log(S)) time. The space overhead is approximately T*(4 bytes + 1 bit).

If the right dataframe has any column names in common with the left, the duplicate right column names will have a suffix appended to them in the result.
    If the left dataframe has S rows and the right has T rows then this join operation will use O(S) space and run in O(S*log(T)) time. The space overhead is approximately S*(4 bytes + 1 bit).
    
    Specified by:
    
    joinManyToOne in interface DataFrame
    
    Parameters:
    
    df - - the right dataframe to be joined with this left one

    If the left dataframe has N columns and the right has M columns then the resulting dataframe will have N + M - 1 columns, starting with all N columns from the left dataframe, followed by the columns from the right dataframe excluding the specified non-index column. If the right dataframe has any column names in common with the left, the duplicate right column names will have a suffix appended to them in the result.
    If the left dataframe has S rows and the right has T rows then this join operation will use O(S + T) space and run in O(T*log(S)) time. The space overhead is approximately S bits, plus T*(4 bytes + 1 bit).

If the right dataframe has any column names in common with the left, the duplicate right column names will have a suffix appended to them in the result.
    If the left dataframe has S rows and the right has T rows then this join operation will use O(S + T) space and time. The space overhead is approximately T bits, plus the space required by an <Integer,Integer> HashMap with S entries, plus an additional S*8 bytes.
