1 Convert List of Strings to List of Floats

In this example,

We have a list of strings named stringList.
We iterate over each string in the list and use the Float.parseFloat() method to parse it as a float.
The result is a list of floats.

Java Program

import java.util.ArrayList;
import java.util.List;

public class Main {
    public static void main(String[] args) {
        List<String> stringList = List.of("1.1", "2.2", "3.3", "4.4", "5.5");
        List<Float> floatList = new ArrayList<>();
        for (String s : stringList) {
            floatList.add(Float.parseFloat(s));
        }
        System.out.println(floatList);
    }
}

Output
