JAVA return unexpected boolean result from method

Why the following method always return false for the below value. Do I confuse with somethings??

public boolean isTwoWay(Detail detail) {
    return (detail.isExchange && detail.isTwoWay && !detail.isIVR);
}

which data contain following

detail.isExchange =  true;
detail.isTwoWay = true;
detail.isIVR = false;

but it return false instead of true

I have tried with that and its print true always.

boolean isExchange =  true;
boolean isTwoWay = true;
boolean isIVR = false;

System.out.println(isExchange && isTwoWay && !isIVR);

The only way the method will return false is if one of your assumptions is wrong:

detail.isExchange =  true;
detail.isTwoWat = true;
detail.isIVR = false;

Rest assured, this kind of oversight happens to programmers all the time, including the best of us.

Put a breakpoint where you receive false instead of your expected true, and verify your assumptions.
