Use String Class Carefully

If two Strings are concatenated using “+” operator in a “for” loop, then it creates a new String Object, every time. This causes wastage of memory and increases performance time.  Also, while instantiating a String Object, constructors should be avoided and instantiation should happen directly. For example: 1 //Slower Instantiation 2 String bad =  new   String( "Yet another string object" ); 3         4 //Faster Instantiation 5 6 String good =  "Yet another string object";
