UnnecessaryParentheses
Sometimes expressions are wrapped in unnecessary parentheses,
making them look like a function call.
      

		
		
		    
    			
This rule is defined by the following XPath expression:
    			
    			
    
                  
          //Expression
           /PrimaryExpression
            /PrimaryPrefix
             /Expression[count(*)=1]
              /PrimaryExpression
              /PrimaryPrefix
              
  
		    
		    
	    
	    
        
        
        
Example:
            
    
                
  public class Foo {
      boolean bar() {
          return (true);
      }
  }
