CollapsibleIfStatements
Sometimes two 'if' statements can be consolidated by separating their conditions with a boolean short-circuit operator.
      
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
                    
//IfStatement[@Else='false']/Statement
 /IfStatement[@Else='false']
 |
//IfStatement[@Else='false']/Statement
 /Block[count(BlockStatement)=1]/BlockStatement
  /Statement/IfStatement[@Else='false']
            
  
		    
		    
	    
	    
        
        
        Example:
            
                    
  
public class Foo {
 void bar() {
  if (x) {
   if (y) {
    // do stuff
   }
  }
 }
}
