Best practice – how do I test for strings in Java?

I render some data according to conditions Support method execution to check whether the string exists But I don't know if I can be satisfied with comparing null?

public boolean isString(MyClass var) {
   return null != var.getMyString();
}

Can we do better?

Solution

I've liked stringutils since Apache commons Lang isNotBlank()：

StringUtils.isNotBlank(var.getMyString())

It performs an additional trim (), which is desirable in most cases If not, use stringutils isNotEmpty(). Another advantage: it uses charsequence, so you can pass string, StringBuilder, etc
