Hi friend,

Code to help in solving the problem :

import java.io.*;
class StringLength
{
public static void main(String[] args) throws Exception
{

String string = "";
InputStreamReader input = new InputStreamReader(System.in);
BufferedReader reader = new BufferedReader(input);
// read in user input
System.out.println("Enter the first word");
String str1=reader.readLine();
System.out.println("Enter the second word");
String str2=reader.readLine();
String str3=str1+""+str2;
int len=str3.length();
int dotlen=0;

if(len<=30)
{
dotlen = 30-len;
}
String strdot="";
for(int i=1;i<=dotlen;i++)
{
strdot+=".";
}
System.out.println("Output String : " +str1+strdot+str3);



}
}


Thanks
