If row
and/or column
is int
, then it doesn't have any method at all since it is a primitive type. Change it to Integer
or use ==
instead.
Int Cannot Be Dereferenced In Equals Method [closed]
Question
I have an equals method in a Position class. The class contains two instance variables, row and col, that represent the location in a grid. I need to be able to check if two different positions are equal, using an equals method. However, with my current equals method I get an "Int cannot be dereferenced" error upon compiling. I cannot find how to fix this, and the instructor has specified that there should be no reason to overwrite the hashcode. My equals method is below, any help is appreciated.
@Override
public boolean equals(Object other) {
if (null == other) return false;
if (this == other) return true;
if (!(other instanceof Position)) return false;
Position that = (Position) other;
return row.equals(that.getRow()) && col.equals(getCol());
}
EDIT: row and col are of type int.
