I have to write a java program So basically I have to take

Solution

import java.io.*;
import java.util.*;

class InchesToCms{
   public static void main (String[] args)throws Exception{
       //1 Inches = 2.54 Centimeters;
       BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));//to get input creating bf is an object.
       System.out.print(\"Enter the inches: \");//asking the input is inches
       float inches = Float.parseFloat(bf.readLine());//geting input first in string,so convert into float using parseFloat function.
       float cms = inches * 2.54f;//multiplying given input inches and 2.54.
       System.out.println(inches + \" inches is \" + cms + \" centimeter(s).\");//display the inches and centimeters.
  
  
       System.out.print(\"Enter the Centimeters: \");//asking the input is Centimeters.
       float CMS = Float.parseFloat(bf.readLine());
       System.out.println(\"You entered \" +CMS+ \" centimeter(s).\");//display out put in Centimeters only.
   }
}

/* Output:
  
      1) Enter the inches: 11.0
          11.0 inches is 27.939999 centimeter(s).
          Enter the Centimeters: 2.0
          You entered 2.0 centimeter(s).  

Explanatin:

This program 1) It takes input in inches and convert into centimeters

                     2) and Next It takes input in centimters and display the out in the same centimeters.
