Answer:
Following are the code to this question:
import java.util.*;//import package for user-input
public class U7_L2_Activity Three//defining class U7_L2_Activity Three
{
public static ArrayList<Integer> getOdds(ArrayList<Integer> val)//defining a static method getOdds as an ArrayList
{
ArrayList<Integer> odd = new ArrayList<Integer>();//creating ArrayList Object
int i; //defining integer variable
for(i=0;i<val.size();i++)//defining for loop for calculating odd values
{
if(val.get(i)%2!=0)//defining if block to check odd numbers
{
odd.add(vals.get(i));//add values in odd ArrayList
}
}
return odd;//return ArrayList odd
}
public static void main(String[] asr)//defining main method
{
int l,i;//defining integer variable
Scanner sob = new Scanner(System.in);//creating Scanner calss Object
ArrayList<Integer> num = new ArrayList<Integer>();//creating ArrayList object
System.out.println("Enter length of the ArrayList: ");//print message
l = scan.nextInt();//input length value
System.out.println("Enter ArrayList values: "); //print message
for(i = 0; i < l; i++)//use for to input value
{
num.add(sob.nextInt());//input value
}
System.out.println("Odds list: " + getOdds(num));//calling method getOdds
System.out.println("Original list: " + num);//print array value
}
}
Output:
Enter ArrayList length:
7
Enter values:
2
5
8
6
7
3
12
Odds list: [5, 7, 3]
Original list: [2, 5, 8, 6, 7, 3, 12]
Explanation:
In the above-program inside the class, a static method "getOdds "is declared, that accepts an array list in its parameters, and defined an array list "odd", in this a for loop is defined, that check the odd numbers in the array and add the value in the odd Arraylist, and returns its values.
Inside the main method is defined that creates scanner class object for input array value and pass the value into the method "getodds" and print its return values.
