Create an array of 5 floats and calculate their sum.

 public class MyClass {

    public static void main(String args[]) {

         float [] marks = {45.7f, 67.8f, 63.4f, 99.2f, 100.0f};

        float sum = 0;

        for(float element:marks){

            sum = sum + element;

        }

        System.out.println("The value of sum is " + sum);

    }

}
