Difficult to know exactly what you mean here but I'll take a shot

StringBuilder sb = new StringBuilder();
for(condition){
    sb.append("some string");
    ...
}
System.out.printf("%s\n", sb.toString());

--or, slightly more disturbingly --

StringBuilder buffer = new StringBuilder();
for(condition){
    StringBuilder sb = new StringBuilder();
    sb.append("whatever");
    ...
    buffer.append(sb.toString());
}
System.out.printf("%s\n", buffer.toString());

can't see the point of this second example although it appears to meet 
your original criteria of creating a new builder for each iteration of 
the loop.
