### Question:
Position { public void set(Position newPosition) { if (newPosition != null) { this.line = newPosition.getLine(); this.column = newPosition.getColumn(); } } Position(int line, int column);  Position(Position position); void incrementLine(); void incrementColumn(); void set(Position newPosition); int getColumn(); String getColumnAsString(); int getLine(); String getLineAsString(); String toString();  }### Answer:
@Test public void testSet() { Position position = new Position(-1, 5); Position anotherPosition = new Position(2, 30); position.set(anotherPosition); assertEquals("line", 2, position.getLine()); assertEquals("lineAsString", "2", position.getLineAsString()); assertEquals("col", 30, position.getColumn()); assertEquals("colAsString", "30", position.getColumnAsString()); }
