Cloning a Java bean with few of the properties values - BeanUtils

Question

I am having a Java bean, which i want to clone it to get a new instance, but in the new instance, I want few of the properties to have values, others i don't want to be cloned/copied.

Example:-

Source:- Class ABC, Object src --> field1 = 10, field2 =5, field3 = 6, field4 = 20
Target:- Class ABC, Oject clone --> field1 = 10, field2 = 5, field3 = null, field4 = null

I can also use copyProperties but than, I have to create a similar but small class structure.

I can also use copyProperty but then, I have to write it multiple times.

Is there a good solution to this.

Answer 1

Use this method copyProperties(Object dest, Object orig) Copy property values from the origin bean to the destination bean for all cases where the property names are the same.
