SuspiciousConstantFieldName


SuspiciousConstantFieldName
A field name is all in uppercase characters, which in Sun's Java naming
conventions indicate a constant. However, the field is not final.
       
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
    
//ClassOrInterfaceDeclaration[@Interface='false']
 /ClassOrInterfaceBody/ClassOrInterfaceBodyDeclaration/FieldDeclaration
  [@Final='false']
  [VariableDeclarator/VariableDeclaratorId[upper-case(@Image)=@Image]]
 
                
  
		    
		    
	    
	    
        
        
        Example:
            
                    
    
public class Foo {
 // this is bad, since someone could accidentally
 // do PI = 2.71828; which is actualy e
 // final double PI = 3.16; is ok
 double PI = 3.16;
}
