AvoidInstanceofChecksInCatchClause


AvoidInstanceofChecksInCatchClause
Each caught exception type should be handled in its own catch clause.
      
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
        
//CatchStatement/FormalParameter
 /following-sibling::Block//InstanceOfExpression/PrimaryExpression/PrimaryPrefix
  /Name[
   @Image = ./ancestor::Block/preceding-sibling::FormalParameter
    /VariableDeclaratorId/@Image
  ]
    
              
  
		    
		    
	    
	    
        
        
        Example:
            
                    

try { // Avoid this
 // do something
} catch (Exception ee) {
 if (ee instanceof IOException) {
  cleanup();
 }
}
try {  // Prefer this:
 // do something
} catch (IOException ee) {
 cleanup();
}
