Since Checkstyle 3.1
Detects empty statements (standalone ";"
semicolon).
Empty statements often introduce bugs that are hard to spot
To configure the check:
<module name="Checker"> <module name="TreeWalker"> <module name="EmptyStatement"/> </module> </module>
Example:
public void foo() { int i = 5; if (i > 3); // violation, ";" right after if statement i++; for (i = 0; i < 5; i++); // violation i++; while (i > 10) // OK i++; }
All messages can be customized if the default message doesn't suit you. Please see the documentation to learn how to.
