Suggestion: Add the method isEmpty in the classes StringBuilder and StringBuffer (original) (raw)

Hello,

we have a scenario where a project with approximately 500K lines of code is going through a large refactoring. One of the changes was to replace string concatenations in loops by StringBuilder. Within the logic we found the following condition:

for(...) { if(str.isEmpty()) { // do something } }

After using StringBuilder,we had to change it to:

for(...) { if(str.length() == 0) { // do something } }

... which is a less readable code than the previous code. Having shown that, we would like to know if there was a previous discution on the inclusion or not of a method isEmpty in the StringBuilder. if yes, why it is not there, if no, can we actually have it on Java8 or in a near future?

We can actually find other similar String-like methods within StringBuilder, such as charAt, replace and others.

We would like to know if it is worthwhile to be discussed and taken forward.

Best regards,
