Is the above code of some help ?

as i have still not arrived at the right answer ?

sorry for the late reply .

The code goes as follows in the getTestValue() the code is as follows:-

public Object getTestValue(){ return (testValue == null ? -1 : testValue); }

so as i could understand the getter is responsible for removing the InvocationException in equals method which was thrown at line
if(this.testValue == myClass.getTestValue()){ return true; }

When i changed the equals as follows:-


public boolean equals(Object object){ if(this == object){ return true; } if(object == null){ return false; } if(object != null){ MyClass myClass = (MyClass)object; if(this.getTestValue() == myClass.getTestValue()){ return true; } } return false; } }

It works and no exception is thrown . In either case , the value of fields of MyClass should be same then why is the behaviuor different on invocation of this.testValue and this.getTestValue()

Hi


I have a piece of code
class MyClass{ Object testValue; public Object getTestValue(){ return testValue; } public void setTestValue(Object testValue){ this.testValue = testValue; } public boolean equals(Object object){ if(this == object){ return true; } if(object == null){ return false; } if(object != null){ MyClass myClass = (MyClass)object; if(this.testValue == myClass.getTestValue()){ return true; } } return false; } } public class testingNulls { public static void main(String[] args){ MyClass myClass = new MyClass(); System.out.print(myClass.testValue); MyClass myClassNew = new MyClass(); boolean setFlag = myClass.equals(myClassNew); System.out.print(" Output "+setFlag); } }
My question comes from equals method in the block
if(this.testValue == myClass.getTestValue()){ return true; }

I had a Myclass object which did not have a testValue associated with it now when i ran the test i got an Invocation exception . This example is in customized form so it might not throw exception . However, in the real code we had to use a getter in the code block as:-
if(this.getTestValue() == myClass.getTestValue()){ return true; }


I could not understand why this worked because fields for the calling object are same in either case . CAn anyone explain ?

about the version i think i would want to appear in a version dealing with J2ee1.6. In case you can suggest please do .

Thank you for your prompt reply but what i am asking is the advantage of one constructor over the other ie the HashCodeBuilder() and the
HashCodeBuilder(int startValue, int multiplier). Can you please explain ?


Thanks
Ragi

Hi all.


I am using org.apache.commons.lang.builder.HashCodeBuilder to generate the hashcode of an object . Can anyone explain where to use the HashCodeBuilder() and where HashCodeBuilder(int initialNonZeroOddNumber, int multiplierNonZeroOddNumber) has to be used . I read the docs but couldnt understand . Can anyone elaborate .

hi ,

I am writing a test case using easy mock but the method i want to test gives a call to the super class method which is also overridden in my subclass . I thought about to approaches one taking out the call to super class method in another method and then mocking this method other being partial mocking . Can anyone suggest whether the approach is correct or is there a way out which is better or there is already something existing in the api to deal with such scenario .


Thanks ,
