public final class Duration

A duration of zero.

A duration of days standard 24 hour days.

A duration of hours hours.

A duration of minutes minutes.

A duration of seconds seconds.

A duration of seconds seconds adjusted by nanoAdjustment nanoseconds, which may take it across any number of seconds.

A duration of millis milliseconds.

A duration of nanos nanoseconds.

A duration of amount of unit. The unit must have an exact length: a day or anything shorter.

The duration amount adds up to. Every unit it is made of must have an exact length.

The duration from one value to another of the same kind, negative when endExclusive comes first.

The amount of unit held: the seconds or the nanoseconds.

Seconds and nanoseconds, the two units a duration is made of.

A zero duration hands temporal back untouched, null included: JDK 8, the conformance host, does the same and throws nothing.

temporal moved back by this amount.

Whether this is zero long.

Whether this is shorter than zero.

The whole seconds, rounded towards negative infinity.

The nanoseconds within the second, 0 to 999,999,999.

This duration with seconds whole seconds.

This duration with nanoOfSecond nanoseconds within the second.

This duration plus amountToAdd of unit, which must have an exact length.

This duration multiplied by multiplicand, or ArithmeticException when the product is longer than a duration holds.

This duration divided by divisor, the fraction of a nanosecond dropped towards zero. Exact for every duration; only a quotient that is not a duration throws ArithmeticException.

This duration with its sign reversed. The most negative duration has no positive counterpart and throws ArithmeticException.

This duration without its sign.

The whole days, of 24 hours.

The whole hours.

The whole minutes.

The whole seconds; the same as getSeconds().

The whole milliseconds, or ArithmeticException past what a long holds.

The whole nanoseconds, or ArithmeticException past what a long holds (about 292 years).

The whole days; the same as toDays().

The hours left over after the whole days.

The minutes left over after the whole hours.

The seconds left over after the whole minutes.

The milliseconds within the second.

The nanoseconds within the second; the same as getNano().

Compares this object to the specified object to determine their relative order.

Indicates whether some other object is “equal to” this one. The equals method implements an equivalence relation: It is reflexive: for any reference value x, x.equals(x) should return true. It is symmetric: for any reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true. It is transitive: for any reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true. It is consistent: for any reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the object is modified. For any non-null reference value x, x.equals(null) should return false. The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any reference values x and y, this method returns true if and only if x and y refer to the same object (x==y has the value true).

Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by java.util.Hashtable. The general contract of hashCode is: Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons 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 the hashCode method 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 equals(java.lang.Object) method, then calling the hashCode method 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 hashtables. As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

Returns a string representation of the object. In general, the toString method 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 toString method for class Object returns 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())
