Question

Write a method called splitArray which will receive four parameters as follows:

• Original array
• Array of multiples
• Array of not multiples
• Number to compare if the values within the original array are multiples of

Assuming that always the original array will contain half values as multiples and half as not multiples. Your method should return the numbers within the original array that are multiples of the last parameter in the array of multiples (second parameter). Furthermore, your method should return the array of not multiples in the third parameter received.

As an example, if the input was 6 7 8 9 3 6 10 3. The Array of multiples would be conformed as 9 3 6 and the array of not multiples would be conformed by 7 8 10. And the output should be as follows.

Multiple[0] = 9
Multiple[1] = 3
Multiple[2] = 6
Not multiple[0] = 7
Not multiple[1] = 8
Not multiple[2] = 10

Keep in mind that you will create the other arrays and they will start without having any element

import java.util.*;

public class Main{

public static void splitArray(int[] ori, int[] mul, int[] not, int val){
  
// Fill your multiple and not multiple arrays here based on the original array
  
}


public static void main(String[] args){
  
Scanner scnr = new Scanner(System.in);
  
int oSize = scnr.nextInt();
  
int[] original = new int[oSize]; // Declaring the original array
int[] multiple = new int[oSize/2]; // Declaring the array of multiple numbers
int[] notMultiple = new int[oSize/2]; // Declaring the array of not multple numbers
int value;
  
  
// Getting the values for the original array
for (int i = 0; i < oSize; i++){
original[i] = scnr.nextInt();
}
  
value = scnr.nextInt();
  
splitArray(original, multiple, notMultiple, value);
  
for (int i = 0; i < oSize / 2; i++){
System.out.printf("Multiple[%d] = %d%n", i, multiple[i]);
}

for (int i = 0; i < oSize / 2; i++){
System.out.printf("Not multiple[%d] = %d%n", i, notMultiple[i]);
}
  
}

}

If you have any doubts, please give me comment...

import java.util.*;

public class Main{

public static void splitArray(int[] ori, int[] mul, int[] not, int val){

  

// Fill your multiple and not multiple arrays here based on the original array

int j=0, k=0;

for(int i=0; i<ori.length; i++){

     if(ori[i]%val==0){

        mul[j] = ori[i];

        j++;

     }

     else{

         not[k] = ori[i];

         k++;

     }

}

}

public static void main(String[] args){

  

Scanner scnr = new Scanner(System.in);

  

int oSize = scnr.nextInt();

  

int[] original = new int[oSize]; // Declaring the original array

int[] multiple = new int[oSize/2]; // Declaring the array of multiple numbers

int[] notMultiple = new int[oSize/2]; // Declaring the array of not multple numbers

int value;

  

  

// Getting the values for the original array

for (int i = 0; i < oSize; i++){

original[i] = scnr.nextInt();

}

  

value = scnr.nextInt();

  

splitArray(original, multiple, notMultiple, value);

  

for (int i = 0; i < oSize / 2; i++){

System.out.printf("Multiple[%d] = %d%n", i, multiple[i]);

}

for (int i = 0; i < oSize / 2; i++){

System.out.printf("Not multiple[%d] = %d%n", i, notMultiple[i]);

}

}

}
