Constructor Detail

MutableInteger

public MutableInteger()

MutableInteger

public MutableInteger(int i)

Method Detail

set

public void set(int i)

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Compares this object to the specified object. The result is true if and only if the argument is not null and is an MutableInteger object that contains the same int value as this object. Note that a MutableInteger isn't and can't be equal to an Integer.

Overrides:

equals in class Object

Parameters:

obj - the object to compare with.

Returns:

true if the objects are the same; false otherwise.

toString

public String toString()

Overrides:

toString in class Object

compareTo

public int compareTo(MutableInteger anotherMutableInteger)

Compares two MutableInteger objects numerically.

Parameters:

anotherMutableInteger - the MutableInteger to be compared.

Returns:

Tthe value 0 if this MutableInteger is equal to the argument MutableInteger; a value less than 0 if this MutableInteger is numerically less than the argument MutableInteger; and a value greater than 0 if this MutableInteger is numerically greater than the argument MutableInteger (signed comparison).

compareTo

public int compareTo(Object o)

Compares this MutableInteger object to another object. If the object is an MutableInteger, this function behaves like compareTo(MutableInteger). Otherwise, it throws a ClassCastException (as MutableInteger objects are only comparable to other MutableInteger objects).

Specified by:

compareTo in interface Comparable

Parameters:

o - the Object to be compared.

Returns:

0/-1/1

Throws:

ClassCastException - if the argument is not an MutableInteger.
