java outOfMemoryError with stringbuilder

Question

I\'m getting a java outOfMemoryError when I call this method - i\'m using it in a loop to parse many large files in sequence. my guess is that result.toString()

Answer 1

I reckon the problem with StringBuilder.append(). When Matcher appends sequence of characters to the Builder.

As explained in article about OutOfMemoryError with StringBuilder/StringBuffer, it is a known issue that append() will double the capacity if internal buffer chars if the capacity is not sufficient. Go for streams as suggested by Erickson.
