It's slightly less efficient ( sb.append() ends up calling Integer.getChars(), which is what Integer.toString() would've done anyway), but it works.
Java has special support for the + operator when used with strings (see the documentation) which translates the code you posted into: StringBuilder sb = new StringBuilder() Īt compile-time. The concatenation will work, but it is unconventional and could be a bad smell as it suggests the author doesn't know about the two methods above (what else might they not know?). Numerous conversion and formatting options. Excellent educational tool for C++ developers learning Java. Fast - tens of thousands of lines converted from C++ to Java per minute. Normal ways would be Integer.toString(i) or String.valueOf(i). Flexible - converts snippets, files, and folders from C++ to Java. Use this String.valueOf(value) How do I convert from int to String?
