Class UnnecessarySemicolonAfterTypeMemberDeclarationCheck

  • All Implemented Interfaces:
    Configurable, Contextualizable
    public final class UnnecessarySemicolonAfterTypeMemberDeclarationCheck
extends AbstractCheck

    Checks if unnecessary semicolon is used after type member declaration.

    This check is not applicable to empty statements (unnecessary semicolons inside methods or init blocks), EmptyStatement is responsible for it.

    To configure the check: 

     <module name="UnnecessarySemicolonAfterTypeMemberDeclaration"/>

    Results in following: 

     class A {
     ; // violation, standalone semicolon
     {}; // violation, extra semicolon after init block
     static {}; // violation, extra semicolon after static init block
     A(){}; // violation, extra semicolon after constructor definition
     void method() {}; // violation, extra semicolon after method definition
     int field = 10;; // violation, extra semicolon after field declaration

     {
         ; // no violation, it is empty statement inside init block
     }

     static {
         ; // no violation, it is empty statement inside static init block
     }

     void anotherMethod() {
         ; // no violation, it is empty statement
         if(true); // no violation, it is empty statement
     }
 }
