Funkcije se uporabljajo za razbijanje in razdelitev ogromne kode na majhne dele, tako da koda postane bolj razumljiva in s tem zmanjša kompleksnost kode. Nizi so homogene podatkovne strukture za zmanjšanje kompleksnosti kode, povečanje učinkovitosti in zmanjšanje časa izvajanja kode. Uporabljamo matriko in mislimo, da sta oba dela programiranja, ki prihranita čas, implementirana skupaj. Tako obstaja koncept prehajanja Array do funkcije.

V tem razdelku se bomo naučili, kako lahko matriko posredujemo uporabniško definirani funkciji in opazili, kako to naredi kodo bolj optimistično in tudi učinkovito.

Na splošno je namen posredovanja matrike funkciji prenos velike količine podatkov med metodami. Če želite matriko posredovati funkciji, le posredujte matriko kot parameter funkcije (kot običajne spremenljivke) in ko matriko posredujemo funkciji kot argument, se dejansko posreduje naslov matrike v pomnilniku, ki je referenca. Tako bodo vse spremembe v matriki znotraj metode vplivale na dejanske vrednosti matrike.

Implementirali bomo nekaj primerov kod, skozi katere bomo spoznali, kako posredovati matriko funkciji.

Primer 1:

Izračun največje in najmanjše vrednosti dane matrike.

Da bi dobili največjo in najmanjšo vrednost v matriki, lahko izvedemo spodnjo kodo:

 import java.util.Scanner; public class array { public int max(int [] array) { int max = 0; for(int i=0; imax) { max = array[i]; } } return max; } public int min(int [] array) { int min = array[0]; for(int i = 0; i <array.length; i++ ) { if(array[i]<min) min="array[i];" } return min; public static void main(string args[]) scanner sc="new" scanner(system.in); system.out.println('enter the array range'); int size="sc.nextInt();" int[] arr="new" int[size]; elements of ::'); for(int i="0;" i<size; i++) arr[i]="sc.nextInt();" m="new" array(); system.out.println('maximum value in is::'+m.max(arr)); system.out.println('minimum is::'+m.min(arr)); < pre> <p> <strong>Output:</strong> </p> <img src="//techcodeview.com/img/java-tutorial/73/passing-array-function-java.webp" alt="Passing Array to Function In Java"> <p> <strong>Code Explanation:</strong> </p> <ul> <li>In the above code, we created a class <strong>array</strong> within which we have created a <strong>max()</strong> function and <strong>min()</strong> </li> <li>In the <strong>max ()</strong> function, we have passed an array as the function parameter, and using for loop, we found the maximum value in the array by indexing i from 0 to the length of the array, and as soon it finds the maximum value, it gets stored in the max variable.
