All Implemented Interfaces:
Configurable, Contextualizable

public class AvoidNestedBlocksCheck
extends Check

Finds nested blocks. For example this Check finds the obsolete braces in

 switch (a)
 {
     case 0:
         {
             x = 1;
         }
         break;
     default:
         break;
 }
 
and flags confusing code like
 public void guessTheOutput()
 {
     int whichIsWich = 0;
     {
         int whichIsWhich = 2;
     }
     System.out.println("value = " + whichIsWhich);
 }
