How to generate hashCode() and equals() for a package in eclipse?

Question

I have various class in this package. Is it possible to generate hashCode() and equals() for all classes in this package at once?

Answer 1

If you need to auto generate hashCode() and equals() in eclipse for each class in certain package

Open every java class >>> right click >> sourse >>> generate hashCode() and equals()

Maybe if the number of classes too big then you can create java task to open every file and append the hashcode() and equals()

Answer 2

Currently Eclipse does not support this feature. Enhancement bug is raised for this.

Answer 3

Not Specific for package but apache common's HashCodebuilder and EqualsBuilder can help you to implement it in correct way

https://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/builder/HashCodeBuilder.html

http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/builder/EqualsBuilder.html

Answer 4

can you imagine when you have implementation of "equal()" for classes and you will choose for package "generate please method equal()" what must decide eclipse ? I think if you want to generate a methods automatically for package of classes - you can make own code..
