Tuple di Jawa

Tuple dianggap sebagai koleksi pelbagai jenis objek yang dipesan. Walaupun objek itu mungkin berkaitan atau mungkin tidak satu sama lain, ia secara kolektif mempunyai makna tertentu. Di Jawa, tiada struktur data terbina yang disokong oleh tupel. Jadi, kelas akan dibuat apabila sebarang keperluan berlaku. Di samping itu, fungsi ini boleh digunakan dalam Senarai dan juga tatasusunan. Walau bagaimanapun, data jenis data yang berbeza tidak dapat mengekalkannya.

Tuple daripada pembina:

Nthtuple<t1,t2,. .  tn> nthtuple= new Nthtuple<t1,t2,. . . . . . . tn>(v1, v2, . . . . , vn)

Kaedah Tuple from with():

Nthtuple<t1,t2,. .  tn> nthtuple= new Nthtuple.with(v1, v2, . . . . , vn)

Tuple daripada koleksi lain:

Nthtuple<t1,t2,.  tn> nthtuple=new Nthtuple.fromCollection(collectionWith nvalues);

Di sini,

• t1, t2, … tn ialah jenis 1, jenis 2,… ., jenis n
• v1, v2, . . ., vn ialah nilai 1, nilai 2, . . . , nilai n
• n ialah bilangan parameter dan bilangan nilai

Ciri-ciri Tuples di Jawa

Berikut ialah ciri utama Tuple di Jawa

• Typesafe
• Boleh diulang
• Laksanakan toString()
• Setanding (Tuple melaksanakan Sebanding)
• Kekal
• Boleh bersiri
• Laksanakan kaedah equals() dan hashCode().

Bagaimanakah Tuples berfungsi di Jawa?

Mari kita ambil contoh tupel.

Di sini, anda dapat melihat bahawa setiap objek tuple ini adalah daripada jenis data yang berbeza. Tetapi, apabila kita pertimbangkan secara kolektif, ia boleh dikenal pasti sebagai butiran seorang pelajar Anna di jabatan Sains Komputer yang berusia 23 tahun.

Nota: Tuples dalam Java menyokong saiz sehingga 10, dan terdapat cara pelaksanaan tertentu untuk setiap saiz tuple, seperti yang ditunjukkan di bawah.

Size of Tuple	Name	Sample
One Element	Unit	Unit<1>
Two Elements	Pair	Pair<1,2>
Three Elements	Triplet	Triplet<1,2,3>
Four Elements	Quartet	Quartet<1,2,3,4>
Five Elements	Quintet	Quintet<1,2,3,4,5>
Six Elements	Sextet	Sextet<1,2,3,4,5,6>
Seven Elements	Septet	Septet<1,2,3,4,5,6,7>
Eight Elements	Octet	Octet<1,2,3,4,5,6,7,8>
Nine Elements	Ennead	Ennead<1,2,3,4,5,6,7,8,9>
Ten Elements	Decade	Decade<1,2,3,4,5,6,7,8,9,10>

Saiz Tuple Nama Sampel Satu Elemen Unit Unit<1> Dua Elemen Pasangan Pasangan<1,2> Tiga Elemen Triplet Triplet<1,2,3> Empat Elemen Kuartet Kuartet<1,2,3,4> Lima Elemen Kuintet Kuintet<1,2,3,4,5> Enam Elemen Sextet Sextet<1,2,3,4,5,6> Tujuh Elemen Septet Septet<1,2,3,4,5,6,7> Lapan Elemen Oktet Oktet<1,2,3,4,5,6,7,8> Sembilan Elemen Ennead Ennead<1,2,3,4,5,6,7,8,9> Sepuluh Elemen Dekad Dekad<1,2,3,4,5,6,7,8,9,10>

Examples to Implement Tuples in Java

Below are the examples mentioned:

Now, let us see some practical examples of tuples.

Example #1

Java program to create a pair tuple of string type

Code:

import org.javatuples.Pair;
public class TupExample {
public static void main(String[] args) {
//create a pair tuple from constructor
Pair<String,String>pobj = new Pair<String,String>("Happy", "Sad");
//print the tuples
System.out.println("Emotions are: " + pobj);
}
}

Output:

Explanation: In this program, a pair tuple is created of string type. For that, the package org.javatuples.Pair has to be imported first. Once it is created, the objects of the tuple can be printed.

Example #2

Java program to create a pair tuple of different data types

Code:

import org.javatuples.Pair;
public class TupExample {
public static void main(String[] args) {
//create a pair tuple from constructor
Pair<String,Integer>pobj = new Pair<String,Integer>("Anna", 23);
//print the tuples
System.out.println("Student is: " + pobj);
}
}

Output:

Explanation: In this program, a pair tuple is created of two different data types, string and integer. Here also, the package org.javatuples.Pair has to be imported first. Once it is created, the objects of the tuple can be printed.

Example #3

Java program to print a pair tuple using with () method.

Code:

import org.javatuples.Pair;
public class TupExample {
public static void main(String[] args) {
//create a pair tuple from constructor
Pair<String,Integer>pobj = Pair.with("Anna", 23);
//print the tuples
System.out.println("Student is: " + pobj);
}
}

Output:

Explanation: Unlike the above programs, a pair tuple is created using with() method in this program. Here also, the package org.javatuples.Pair has to be imported first. Once it is created, the objects of the tuple can be printed.

Example #4

Java program to create an octet tuple of integer type

Code:

import org.javatuples.Octet;
public class TupExample {
public static void main(String[] args) {
//create an octet tuple from constructor
Octet<Integer,Integer,Integer,Integer,Integer,Integer,Integer,Integer>pobj = Octet.with(12, 23, 34, 45, 56, 67, 78, 89);
//print the tuples
System.out.println("Numbers are: " + pobj);
}
}

Output:

Explanation: In this program, an octet tuple is created using with () method. Here, the package org.javatuples.Octet has to be imported first. Once it is created, the objects of the tuple can be printed.

Example #5

Java program to create decade tuple of integer type using fromCollection()

Code:

import java.util.ArrayList;
import java.util.List;
import org.javatuples.Decade;
public class TupExample {
public static void main(String[] args) {
// Create a li of 10 elements
List<Integer>li = new ArrayList<Integer>();
li.add(12);
li.add(23);
li.add(34);
li.add(45);
li.add(56);
li.add(67);
li.add(78);
li.add(89);
li.add(90);
li.add(101);
Decade<Integer, Integer, Integer, Integer, Integer, Integer, Integer, Integer, Integer, Integer>dobj
= Decade.fromCollection(li);
Integer[] a = { 12, 23, 34, 45, 56, 67, 78, 89, 90, 101 };
Decade<Integer, Integer, Integer, Integer, Integer, Integer, Integer,
Integer, Integer, Integer>dnew = Decade.fromArray(a);
System.out.println("Numbers are: " +dobj);
System.out.println("Numbers are: " +dnew);
}
}

Output:

Explanation: In this program, a decade tuple is created using fromCollection () method. For that, first, a list has to be created with 10 elements. These 10 elements will later gets printed using the fromCollection() method. Here, the package org.javatuples. A decade has to be imported first. Only after importing this, the objects of the tuple can be printed.

Example #6

Java program to create an octet tuple using with() and fromCollection() method.

Code:

import java.util.ArrayList;
import java.util.List;
import org.javatuples.Octet;
public class TupExample {
public static void main(String[] args) {
//create an octet tuple from constructor
Octet<Integer,Integer,Integer,Integer,Integer,Integer,Integer,Integer>pobj = Octet.with(12, 23, 34, 45, 56, 67, 78, 89);
//print the tuples
System.out.println("Numbers using with() method are: " + pobj);
// Create a list of 8 elements
List<Integer>li = new ArrayList<Integer>();
li.add(12);
li.add(23);
li.add(34);
li.add(45);
li.add(56);
li.add(67);
li.add(78);
li.add(89);
Octet<Integer, Integer, Integer, Integer, Integer, Integer, Integer, Integer>dobj
= Octet.fromCollection(li);
System.out.println("Numbers using the fromCollection() method are: " +dobj);
}
}

Output:

Explanation: In this program, an octet tuple is created using fromCollection () and with() method.
