Package com.puppycrawl.tools.checkstyle.checks.coding

Class MultipleVariableDeclarationsCheck

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

    Checks that each variable declaration is in its own statement and on its own line.

    Rationale: the Java code conventions chapter 6.1 recommends that declarations should be one per line/statement.

    To configure the check: 

     <module name="MultipleVariableDeclarations"/>

    Example: 

     public class Test {
   public void myTest() {
     int mid;
     int high;
     // ...

     int lower, higher; // violation
     // ...

     int value,
         index; // violation
     // ...

     int place = mid, number = high;  // violation
   }
 }
