what is best way to model many-to-many relationship?

lets say we have a two classes , Team and Player

• any given Player can be in multiple Team s
• any Team can have as many Player s as they like

I like to call methods like

• playerX.getTeamList() to get the list of all the Team s he/she is in
• teamY.getPlayerList() to get the list of all the Player s in the team

(or have some other way to do this effectively)

I can think of two ways of doing this , but they just don't feels like good oop pattens. can you think of any good ways , perhaps a design patten ?
