Program 1

public class float_Keyword{
        public static void main(String args[]){
            float d1=35.87f; //float keyword is used as variable
            float d2=43.6f;
            float result=d1+d2;
            System.out.println("The result is :"+result);
                    }

            }

The result is : 79.47

 

 

program 2

public class float_Keyword1{
        public static void main(String args[]){
        add(14.56f,46.7f);
        }
        static float add(float a,float b){
            //float keyword is used with method
        float result=a+b;
        System.out.println("The result is :"+result);
        return result;//return value
                    }

            }
