Question

I would like to create a string that HAVE trailing spaces to complete a stringbuffer width.

e.g:

Stringbuffer str = new Stringbuffer(10);  //Create a string with 10 spaces.
str.append("Hello");

The output is
“Hello” without any trailing spaces.
But what I want is “Hello” with 5 trailing spaces.

In the above example, since “Hello” has 5 characters, there should be 5 more trailing spaces after it.

Please advice, thx

Just append a space until the length is less than 10:

while(str.length() < 10) {
    str.append(" ");
}
