InefficientStringBuffering


InefficientStringBuffering
Avoid concatenating non literals in a StringBuffer constructor or append().
    
		
		
		    
		    
    		    
    		    
    		    

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

public class Foo {
 void bar() {
  // Avoid this
  StringBuffer sb=new StringBuffer("tmp = "+System.getProperty("java.io.tmpdir"));
  // use instead something like this
  StringBuffer sb = new StringBuffer("tmp = ");
  sb.append(System.getProperty("java.io.tmpdir"));
 }
}
