String Performance
Perhaps string concatenation is the most frequently used string operation in any language. In Java you can concat two string in this manner: String concatdStr = "String1"+"String2"+" and String3"; But this is not a good idea. Behind the curtain , Java does string concatenation using StringBuffer class. So the above concat becomes : String sBuf = new StringBuffer(32); sBuf.append("String1").append("String2").append(" and String3");
