Možemo izraditi java program za sortiranje elemenata niza korištenjem selekcijskog sortiranja. U algoritmu sortiranja odabirom, tražimo najniži element i raspoređujemo ga na odgovarajuću lokaciju. Mijenjamo trenutni element sa sljedećim najmanjim brojem.

Kako funkcionira selekcijsko sortiranje?

Algoritam sortiranja selekcije radi na vrlo jednostavan način. Održava dva podniza za dati niz.

arraylist

• Podniz je već sortiran.
• A drugi podniz nije razvrstan.

Sa svakom iteracijom odabira sortiranja, element se bira iz nesortirane podmarice i premješta u sortiranu podmatricu.

pd.spojiti

 arr[] = 25 35 45 12 65 10 // Find the minimum element in arr[0...5] and place it at beginning. 10 25 35 45 12 65 // Find the minimum element in arr[1...5] and place it at beginning of arr[1...5] 10 12 25 35 45 65 // Find the minimum element in arr[2...5] and place it at beginning of arr[2...5] No, you can see that the array is already sorted. 10 12 25 35 45 65

Sortiranje odabira u Javi (drugi način)

Također možete koristiti metodu u kojoj niz nije unaprijed definiran. Ovdje korisnik mora staviti elemente kao unos.

U sljedećem Java programu tražimo od korisnika da unese elemente niza ili broj, sada usporedite element niza i započnite zamjenu s varijablom temp. Stavite prvi element u temp i drugi element u prvi, a zatim temp u drugi broj i nastavite za sljedeće podudaranje da sortirate cijeli niz uzlaznim redoslijedom.

 import java.util.Scanner; public class SelectionSortExample2 { public static void main(String args[]) { int size, i, j, temp; int arr[] = new int[50]; Scanner scan = new Scanner(System.in); System.out.print(&apos;Enter Array Size : &apos;); size = scan.nextInt(); System.out.print(&apos;Enter Array Elements : &apos;); for(i=0; i<size; i++) { arr[i]="scan.nextInt();" } system.out.print(\'sorting array using selection sort technique..
\'); for(i="0;" i<size; for(j="i+1;" j arr[j]) temp="arr[i];" arr[j]="temp;" system.out.print(\'now the after sorting is :
\'); system.out.print(arr[i]+ \' \'); < pre> <p>Output:</p> <strong> Use image SelectionSort</strong> </size;>
