can getters be used in equals and hashcode?
java
Solution
You can, but why would you? Option A: the compiler inlines that, so you end up with a reference to the field anyway. Option B: The compiler does not inline the call, i.e. you've introduced one extra method call.
There are also implications for legibility- if the `name` field is directly accessible within the class, why not refer to it directly? I find this easier to read, but some people find it inconsistent.
Problem
I have below code which overrides equals() and hashcode() methods. ``` public boolean equals(Object obj) { if (obj == null) return false; if (!(obj instanceof Name)) return false; Name name = (Name) obj; return this.name.equals(name.name); } public int hashCode() { return name.hashCode(); } ``` here can i replace below 2 lines: ``` return this.name.equals(name.name); return name.hashCode(); ``` with ``` return this.getName().equals(name.getName()); return getName().hashCode(); ``` i mean instead of using properties can i directly use getters inside equals and hashcode methods? Thanks!
