```
public abstract java.lang.Object clone()
```
    Makes a copy of a bounds object.
    
    Overrides:
    
    clone in class java.lang.Object
  - equals
```
public abstract boolean equals(java.lang.Object bounds)
```
    Indicates whether the specified bounds object is equal to this Bounds object. They are equal if both the specified bounds object and this Bounds are instances of the same Bounds subclass and all of the data members of bounds are equal to the corresponding data members in this Bounds.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    bounds - the object with which the comparison is made.
    
    Returns:
    true if this Bounds object is equal to bounds; otherwise false

  - hashCode
```
public abstract int hashCode()
```
    Returns a hash code for this Bounds object based on the data values in this object. Two different Bounds objects of the same type with identical data values (i.e., Bounds.equals returns true) will return the same hash code. Two Bounds objects with different data members may return the same hash code value, although this is not likely.
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    a hash code for this Bounds object.
