org.sonar.l10n.pmd.rules.pmd.LocalVariableCouldBeFinal.html Maven / Gradle / Ivy

A local variable assigned only once can be declared final. Example :
  
public class Bar {
 public void foo () {
  String a = "a"; //if a will not be assigned again it is better to do this:
  final String b = "b";
 }
}
