EmptyStatement

Since Checkstyle 3.1

Description

Detects empty statements (standalone ";" semicolon). Empty statements often introduce bugs that are hard to spot

Examples

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++;
}
