Here it comes...

package replace;

/**
*

*/

import java.io.*;
public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        String mystring =" ";
    System.out.println("Enter the string");
     BufferedReader stdin = new BufferedReader( new InputStreamReader( System.in ) );

            try
            {
                mystring = stdin.readLine();
            } catch ( IOException e) { };

       StringBuffer output =new StringBuffer(' ') ;

       for (int i=0;i<mystring.length();i++)
       {
          if (mystring.charAt(i)!=' ')
               output.append("*");
          else
               output.append(" ");
                       }
     System.out.println(output);
    }

}

Here it goes:

       String a="Nepal is beautiful";
       String b="";

        int n=a.length();
        for(int i=0;i<n;i++){
            if(Character.isWhitespace(a.charAt(i))){
                b+=" ";
            }
            else{
                b+="*";
            }
        }
       System.out.println(b);
