I have List of Records for which I want to find out Maximum value for particular Field:

Can anyone suggest me, any efficient way (rather than writing Sorting Method)

Example :

public decimal maxField1;
public decimal maxField2;

.....
{

List<MyObject__c> listMO = [SELECT ID, Team__c,Field1__c,Field2__c FROM  MyObject__c WHERE xyz__c='abc'];

//Assume I have Map of Teams like below (Not used code here)
MyMap { (Team1,<MyObject1, MyObject2>),
        (Team2,<MyObject3, MyObject4>)
      }
//calling myMethod to get maximum
for(ID key :MyMap.keyset()){
       myMethod(MyMap.get(key));
}
}
...
..
//Find maximum of Field1, field2 for each Team

//---right now I am using SOQL - which I dont want to use

public void myMethod(List<MyObject__c> lstParameter){

 maxField1 = [SELECT Max(field1__c) FROM MyObject__c WHERE ID IN: lstParameter];
}

HERE : I dont want to use SOQL's anymore ....... is there any way that I can find out "Maximum of 'Field Value' for only given List of records at movement.

Any Suggestions! Help !

EDITS :

"Comparable Interface" is the one way - can anyone explain it with simplest real time example (Not Salesforce HelpPage)
