Get Smaller Elements

Lecture 72:-  Get Smaller Elements

To get all elements smaller than a specified value from an ArrayList in Java, you can create a new ArrayList and add the elements that satisfy the condition (i.e., smaller than the specified value) to this new list. Here's how you can do it:

javaCopy code
import java.util.ArrayList;

public class GetSmallerElements {
    public static void main(String[] args) {
        ArrayList<Integer> numbers = new ArrayList<>();
        numbers.add(12);
        numbers.add(7);
        numbers.add(8);
        numbers.add(5);
        numbers.add(18);
        numbers.add(6);
        numbers.add(10);

        // Specified value to compare against
        int specifiedValue = 9;

        // ArrayList to store smaller elements
        ArrayList<Integer> smallerElements = new ArrayList<>();

        for (Integer num : numbers) {
            if (num < specifiedValue) {
                smallerElements.add(num);
            }
        }

        // Print the list of smaller elements
        System.out.println("Smaller elements than " + specifiedValue + ": " + smallerElements);
    }
}

Output:

lessCopy code
Smaller elements than 9: [7, 8, 5, 6]

In this example, we have an ArrayList called numbers containing various integers. We specify a value specifiedValue (in this case, 9) that we want to compare the elements against.

We create a new ArrayList called smallerElements to store the elements that are smaller than specifiedValue. Then, we iterate through the numbers list, and for each element, we check if it is smaller than specifiedValue. If it is, we add it to the smallerElements list.

Finally, we print the smallerElements list to see the elements that are smaller than the specified value.
