LocalVariableCouldBeFinal

A local variable assigned only once can be declared final.
This rule is defined by the following Java class: net.sourceforge.pmd.lang.java.rule.optimizations.LocalVariableCouldBeFinalRule
Example(s):


  
public class Bar {
	public void foo () {
		String txtA = "a"; 		// if txtA will not be assigned again it is better to do this:
		final String txtB = "b";
	}
}
