Java: Need advice on String manipulation program

[fallenshadow]

I wrote this simple program a while back but it doesn't quite work properly.

For some reason the surname is repeated. Any ideas?

class StringTest
{
  public static void main(String[] args)
  {
    String str1 = new String();
    String str2 = new String();
    char initial=' ', firstletsn;
    int i=0, start=0, end=0, endstr;
  
    System.out.print("Enter your firstname followed by your surname ");
    str1 = EasyIn.getString();
    endstr = str1.length();
  
    while (i < endstr)
    {
        System.out.println(str1.charAt(i)+ " " + i);
        i++;
    }
    
    i=0;
    
        while(str1.charAt(i)== ' ')
        i++;
        start=i;
        
        initial = str1.charAt(start);
        str1 = str1.toLowerCase();
         
        while ((str1.charAt(i)>='a')&&(str1.charAt(i)<='z'))
        i++;
        
        
        while(i < endstr)
        {
            System.out.println(str1.charAt (i) + " " + i);
            i++;
        }
        end = i;
    str2 = str1.substring(start,end);
    firstletsn = str2.charAt(start);
    str2 = str2.toUpperCase();
    firstletsn = str2.charAt(0);
    str2 = str2.substring(1,str2.length());
    str2 = str2.toLowerCase();
    
    System.out.println(firstletsn+str2 + " " + initial + ".");
    
  }
} 

I was gonna study this for an upcoming test but since its faulty then there is no point in studying something wrong!

What's EasyIn?

[fallenshadow]

It is just a class that takes input.. no need to worry about that.

Works the same as scanner.

You'll have to tell me what kinf of input your program expects, ten. just the surname or first name + surname ?

[fallenshadow]

The program expects the first name followed by the surname. Like this:

firstname surname

The letters are outputed one by one... except the surname gets repeated a second time.. I need to know why this happens.

It organizes the name in the correct way at the end. The end output is correct.

Well ... if I'm understanding you correctly, it's because you print it out twice (There are two "while" loops with

System.out.println(str1.charAt (i) + " " + i)

in them; comment out the second).

It organizes the name in the correct way at the end. The end output is correct.

Is the output for

Jebediah Bootlace

really supposed to be

Jebediah bootlace J.

?

[ofnuts]

In the real word, this code would be written using a regular expression...

It is also some code which won't work outside of English-speaking countries (and even then...), and I'm not talking about the futility of the "initial" in ideographic languages, but of the test of the a-z range.

Oh silly me... I was tired when I posted this.

Please forgive me for posting up such a stupid question.

Thanks General Zod! Your reply was very helpful!
