StringUtils.isBlank() vs String.isEmpty() :
StringUtils.isBlank()
will also check for null, whereas this:
String foo = getvalue("foo");
if (foo.isEmpty())
will throw a NullPointerException
if foo
is null.
Second Solv –
StringUtils.isBlank
also returns true
for just whitespace:
isBlank(String str)
Checks if a String is whitespace, empty ("") or null.
