StringJoiner is a class which is used to construct a sequence of characters which are separated by a delimiter. Here getValue returns the values stored in the pair and SetValues sets the values of the pairs. Pairs provide a convenient way of handling simple keys to value association and are particularly useful when we want to return two values from a methodA simple implementation of a Pair is available in the core Java libraries eg.

This class is found in javautil package. These can be called only by creating the object of the class. Java Pair class stores value in the key-value pair combination.
Pair Class in Java. Similarly setAt1 set the value at index 1. Add Pair tuple returns Quartet and upto add Octet tuple returns Decade tuple.
Lets take an example of stdpair in C where its first and second fields can be anything. We can initialize an object of this class by using the following syntax. String value pairgetValue.
V getValue Gets the value for this pair. C doesnt indicate what the data pair class stores. O - the Object to test for equality with this Pair.
Int hashCode Generate a hash code for this Pair. These are the top rated real world Java examples of Pair extracted from open source projects. We can call functions on this.
String toString String representation of this Pair. It is useful for getting two values. Optionally it starts with a provided prefix and ended with the provided suffix.

This class extends the Object class. GetSecond30 getFirst30 of30 create30 getValue25. Similarly other methods to add tuples are available eg.
Java Pair - 30 examples found. A Java pair class is a container a tuple of two objects. MapEntry pairMapentryvalue1value2since Java 9 MapEntry tuplenew AbstractMapSimpleEntryvalue1value2until Java 8 String val1tuplegetKey.
It stores a tuple of two objects. If the Object to be tested is not a Pair or is null then this method returns false. The constructor of this class takes two arguments a key and its corresponding value.
Two Pair s are considered equal if and only if both the names and values are equal. Pair class does not specify the relationship between the specified values but is often useful to. This key-value combination is known as tuples.
