 Geetha said: (Wed, Jul 6, 2011 01:49:19 AM) && (comparision between two oprands) in the above two conditions are false so the ans is false. &&: It check two conditions true the result is true otherwise false. If one condition is true other condition is false then again the ans is false.

 Azlan Tanveer said: (Thu, Apr 5, 2012 08:24:37 PM) && operator is comes under logical operator, if all operands i.e. conditions are true it evaluates to true and if any one or more than one or all of them are wrong it will evaluate to false. It is necessary that all conditions should be true.

 Noora said: (Tue, Apr 17, 2012 09:35:05 AM) 3>6 is false 7>4 is true In this expression AND condition is used In and if one statement is false all result is false 3>6&&7>4

 Shariq said: (Mon, Sep 17, 2012 07:56:02 PM) First condition evaluated is 3>6 which is not true, condition is not checked further. After which, if it was written 3<6, which is true then only second condition is tested for its trueness or false, Let us consider condition before && evaluated true. 2 cases arise if the next condition is true or not. Accordingly then, use of && operator states if any one of i/p is false then result is false.
