The following explanation was not tested. public void debug(Object ... params) { StringBuffer sb = new StringBuffer(); for (Object param: params) { sb.append(param); } log.debug(sb); } Someone else pointed out that lazy reads are simple to implement by relying on objects’ toString() methods and variable argument list.

lazyLog.debug(”Found “, person);

public void debug(Object … params) {
StringBuffer sb = new StringBuffer();
for (Object param: params) {
sb.append(param);
