-
equals
public boolean equals(@CheckForNull Object obj)
Description copied from class:java.lang.ObjectIndicates whether some other object is "equal to" this one.The
equalsmethod implements an equivalence relation on non-null object references:- It is reflexive: for any non-null reference value
x,x.equals(x)should returntrue. - It is symmetric: for any non-null reference values
xandy,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any non-null reference values
x,y, andz, ifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue. - It is consistent: for any non-null reference values
xandy, multiple invocations ofx.equals(y)consistently returntrueor consistently returnfalse, provided no information used inequalscomparisons on the objects is modified. - For any non-null reference value
x,x.equals(null)should returnfalse.
The
equalsmethod for classObjectimplements the most discriminating possible equivalence relation on objects; that is, for any non-null reference valuesxandy, this method returnstrueif and only ifxandyrefer to the same object (x == yhas the valuetrue).Note that it is generally necessary to override the
hashCodemethod whenever this method is overridden, so as to maintain the general contract for thehashCodemethod, which states that equal objects must have equal hash codes.- Specified by:
equalsin interfaceRangeSet<C extends Comparable>- Overrides:
equalsin classObject- Parameters:
obj- the reference object with which to compare.- Returns:
trueif this object is the same as the obj argument;falseotherwise.- See Also:
Object.hashCode(),HashMap
- It is reflexive: for any non-null reference value
-
hashCode
public final int hashCode()
Description copied from class:java.lang.ObjectReturns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided byHashMap.The general contract of
hashCodeis:- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
hashCodemethod must consistently return the same integer, provided no information used inequalscomparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. - If two objects are equal according to the
equals(Object)method, then calling thehashCodemethod on each of the two objects must produce the same integer result. - It is not required that if two objects are unequal
according to the
Object.equals(java.lang.Object)method, then calling thehashCodemethod on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
As much as is reasonably practical, the hashCode method defined by class
Objectdoes return distinct integers for distinct objects. (The hashCode may or may not be implemented as some function of an object's memory address at some point in time.)- Specified by:
hashCodein interfaceRangeSet<C extends Comparable>- Overrides:
hashCodein classObject- Returns:
- a hash code value for this object.

an execution of a Java application, the
-
toString
public final String toString()
Description copied from class:java.lang.ObjectReturns a string representation of the object. In general, thetoStringmethod returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.The
toStringmethod for classObjectreturns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:getClass().getName() + '@' + Integer.toHexString(hashCode())
- Specified by:
toStringin interfaceRangeSet<C extends Comparable>- Overrides:
toStringin classObject- Returns:
- a string representation of the object.
