PrematureDeclaration

PrematureDeclaration

Checks for variables that are defined before they might be used. A reference is deemed to be premature if it is created right before a block of code that doesn’t use it that also has the ability to return or throw an exception.
This rule is defined by the following Java class: net.sourceforge.pmd.lang.java.rule.optimizations.PrematureDeclarationRule
Example(s):


              
public int getLength(String[] strings) {
  
  int length = 0;	// declared prematurely

  if (strings == null || strings.length == 0) return 0;
  
  for (String str : strings) {
    length += str.length();
    }

  return length;
}
