### Question:
LayoutConstraintsDescriptor implements Bean { @Override public boolean equals(Object obj) { if (obj == this) { return true; } if (!(obj instanceof LayoutConstraintsDescriptor)) { return false; } LayoutConstraintsDescriptor descriptor = (LayoutConstraintsDescriptor) obj; return prefWidth == descriptor.prefWidth && prefHeight == descriptor.prefHeight; } private  LayoutConstraintsDescriptor(double prefWidth, double prefHeight); static LayoutConstraintsDescriptor getLayoutConstraints(double prefWidth, double prefHeight); static LayoutConstraintsDescriptor prefWidth(double prefWidth); static LayoutConstraintsDescriptor prefHeight(double prefHeight); static LayoutConstraintsDescriptor flexible(); double getPrefWidth(); void setPrefWidth(double prefWidth); double getPrefHeight(); void setPrefHeight(double prefHeight); static boolean isFlexible(double size); static boolean isPreferred(double size); @Override void addPropertyChangeListener(String propertyName, PropertyChangeListener listener); @Override void removePropertyChangeListener(String propertyName, PropertyChangeListener listener); @Override String toString(); @Override int hashCode(); @Override boolean equals(Object obj); static final String PREF_WIDTH_PROPERTY_NAME; static final String PREF_HEIGHT_PROPERTY_NAME; static final double FLEXIBLE_PREF; }### Answer:
@Test @Disabled public void testEquals() { System.out.println("equals"); Object obj = null; LayoutConstraintsDescriptor instance = null; boolean expResult = false; boolean result = instance.equals(obj); assertEquals(expResult, result); fail("The test case is a prototype."); }
