All Implemented Interfaces:

Cloneable, Serializable

IntPair

public IntPair(int i1,
               int i2)

Create a new IntPair object.

Parameters:

i1 - The first integer in the pair.

Method Detail

getI1

public int getI1()

Return the first integer.

Returns:

Return the integer.

getI2

public int getI2()

Return the second integer.

Returns:

Return the integer.

equals

public boolean equals(Object o)

Override the default equals() method. Should return true for all instances where i1 == i1 and i2 == i2, or i1 == i2 and i2 == i1. It can only return true if ip is an IntPair object.

Overrides:

equals in class Object

Returns:

true if the two objects are equal, or false.

hashCode

public int hashCode()

Override the default hashCode() method. Should return the same value for two IntPair objects if ip1.equals(ip2) is true.

Overrides:

hashCode in class Object

clone

public Object clone()

Override the Object.clone() method.

Overrides:

clone in class Object

Returns:

An IntPair object which is a clone of this one.
