String.format() throws FormatFlagsConversionMismatchException
10,454
You asked for a workaround; just use StringBuilder:
public static String padLeft(String s, int n) {
if (n <= 0)
return s;
int noOfSpaces = n * 2;
StringBuilder output = new StringBuilder(s.length() + noOfSpaces);
while (noOfSpaces > 0) {
output.append(" ");
noOfSpaces--;
}
output.append(s);
return output.toString();
}

This code works fine in Java 1.6:
public static String padLeft(String s, int n) { if (n <= 0) return s; int noOfSpaces = n * 2; String output; noOfSpaces = s.length() + noOfSpaces; output = String.format("%1$#" + noOfSpaces + "s", s); return output; }
But newer versions (and some other VM implementations) throw this
Exception
:java.util.FormatFlagsConversionMismatchException: Mismatched Convertor =s, Flags= # at java.util.Formatter$Transformer.transformFromString(Formatter.java:1020) at java.util.Formatter$Transformer.transform(Formatter.java:861) at java.util.Formatter.format(Formatter.java:565) at java.util.Formatter.format(Formatter.java:509) at java.lang.String.format(String.java:1961)
Any workarounds?
