UseIndexOfChar


UseIndexOfChar
Use String.indexOf(char) when checking for the index of a single character; it executes faster.
    
		
		
		    
		    
    		    
    		    
    		    

    		    This rule is defined by the following Java class:
    		    net.sourceforge.pmd.rules.strings.UseIndexOfChar
    		    
		    
	    
	    
        
        
        Example:
            
                    

public class Foo {
 void bar() {
  String s = "hello world";
  // avoid this
  if (s.indexOf("d") {}
  // instead do this
  if (s.indexOf('d') {}
 }
}
