                16          vs=4.0/3.0 * 3.14 * r * r * r;
                17          System.out.println("Volume of a sphere : "+vs + " cu cm ");

                18          System.out.println("-----------------------");
                19          System.out.print("Enter length of a cuboid in cm  : ");

                20          l=sc.nextInt();
                21          System.out.print("Enter breadth of a cuboid in cm : ");

                22          b=sc.nextInt();
                23          System.out.print("Enter height of a cuboid in cm  : ");

                24          h=sc.nextInt();
                25          vcd=l * b * h;
                26          System.out.println("Volume of a cuboid : "+vcd + " cu cm ");

                27          System.out.println("-----------------------");

                28      }
                29  }

              Hint:
              Volume of a cube (vc) = s * s * s          where s is a side of cube.
              Volume of a sphere (vs) = 4 / 3 * π * r * r * r    where π = 3.14 or 22 / 7 and r is a radius of sphere
              Volume of a cuboid (vcd) = l * b * h

              You will get the following output:



















                   5.5 USING InputStreamReader CLASS
              Similar to the Scanner class, the InputStreamReader class is also used to take the input from the user during the execution
              of the program. It takes input in the form of bytes and converts it into characters. To use the InputStreamReader class,
              we need another class called BufferedReader. The BufferedReader class allows us to read data line by line. To utilize
              the InputStreamReader class we need to import a package called java.io as follows:
              import java.io.*;
              //Used for including the package

              BufferedReader br= new BufferedReader(new InputStreamReader(System.in));
              //Used to create the object
