Perhaps I should have made myself a bit clearer; it wasn't necessarily
calling the log method of the logger. Rather, I should have said that the
logger can do a println statement, instead of building a temporary
StringBuffer (which is in effect what the java.text format does)
class Logger {
Writer out;
logString pattern, int i) {
//parsepattern
StringBuffer buffer = new StringBuffer();
buffer.add(firstPartOfPattern);
buffer.add(String.valueOf(i));
buffer.add(secondPartOfPattern);
out.write(buffer.toString());
out.writeln();
}
}
class Logger {
Writer out;
logString pattern, int i) {
//parsepattern
out.write(firstPartOfPattern);
out.write(String.valueOf(i));
out.write(secondPartOfPattern);
out.writeln();
}
}
