        Why is this an issue?

        More Info

        Empty statements represented by a semicolon ; are statements that do not perform any operation. They are often the result of a typo or a misunderstanding of the language syntax. It is a good practice to remove empty statements since they don’t add value and lead to confusion and errors.

        Code examples

        Noncompliant code example

        void doSomething() {
          ;                                  // Noncompliant - was used as a kind of TODO marker
        }
        
        void f() {
          if (complicated.expression.foo()); // Noncompliant - the condition doesn't apply to bar
            bar();
        }
        
        void f() {
          if (complicated.expression.foo())
            bar();
          else ;                             // Noncompliant else is empty
            buzz();
        }
        

        Compliant solution

        void doSomething() {
        }
        
        void f() {
          if (complicated.expression.foo()) {
            bar();
          }
        }
        
        void f() {
          if (complicated.expression.foo())
            bar();
          else
            buzz();
        }
