+
+## Explanation
+
+### Constructor
+
+The constructor takes two `Queen` objects, `queen1` and `queen2`, and stores them as instance variables after validating the following conditions:
+
+- Either queen is `null`.
+- Both queens occupy the same position.
+
+If either of these conditions is true, an exception is thrown.
+
+### `canQueensAttackOneAnother` Method
+
+This method calculates the row and column differences between the two queens and checks the following conditions:
+
+- The row difference is zero (the queens are on the same row).
+- The column difference is zero (the queens are on the same column).
+- The row and column differences are equal (the queens are on the same diagonal).
+
+If any of these conditions are true, the method returns `true`, indicating that the queens can attack each other.

+# Introduction
+
+In this exercise, we determine if two queens on a chessboard can attack each other based on their positions.
+A queen in chess can move any number of squares horizontally, vertically, or diagonally.
+The task is to check if two queens, placed on specific coordinates, can attack each other.
+
+## General Guidance
+
+The problem boils down to checking three conditions:
+
+1. **Same Row**: The queens are on the same row.
+2. **Same Column**: The queens are on the same column.
+3. **Same Diagonal**: The queens are on the same diagonal, i.e., the absolute difference between their row and column positions is equal.
+
+## Approach: Difference Comparison Approach
+
+```java
+class QueenAttackCalculator {
+    private final Queen queen1;
+    private final Queen queen2;
+    
+    QueenAttackCalculator(Queen queen1, Queen queen2) {
+        if (queen1 == null || queen2 == null) {
+            throw new IllegalArgumentException("You must supply valid positions for both Queens.");
+        }
+        if (queen1.getRow() == queen2.getRow() && queen1.getColumn() == queen2.getColumn()) {
+            throw new IllegalArgumentException("Queens cannot occupy the same position.");
+        }
+        this.queen1 = queen1;
+        this.queen2 = queen2;
+    }
+
+    boolean canQueensAttackOneAnother() {
+        int rowDifference = Math.abs(queen1.getRow() - queen2.getRow());
+        int columnDifference = Math.abs(queen1.getColumn() - queen2.getColumn());
+        return rowDifference == 0 || columnDifference == 0 || rowDifference == columnDifference;
+    }
+}
+```
