Evaristo commented on LANG-1410:
--------------------------------
There is minor memory saving with Yifan Guo approach when cs is null, because
Java primitives have a default value when assignment is not explicit to a given
value
int strLen; // This is euqivalent to int strLen = 0;
if (cs == null || (strLen = cs.length()) == 0) {
return true;
}
That means that when cs is null variable strLen is using some memory
This code saves memory when cs == null
if (cs == null) {
return true;
}
int strLen = cs.length();
if ( strLen == 0) {
return true;
}
> StringsUtil.isBlank check null first
