Is it better to use List or Collection?
- by Vivin Paliath
I have an object that stores some data in a list. The implementation could change later, and I don't want to expose the internal implementation to the end user. However, the user must have the ability to modify and access this collection of data. Currently I have something like this:
public List<SomeDataType> getData() {
return this.data;
}
public void setData(List<SomeDataType> data) {
this.data = data;
}
Does this mean that I have allowed the internal implementation details to leak out? Should I be doing this instead?
public Collection<SomeDataType> getData() {
return this.data;
}
public void setData(Collection<SomeDataType> data) {
this.data = new ArrayList<SomeDataType>(data);
}
