Conversion from primitive types to String and vice-versa

Conversion to String
Converting from primitive type to String can be done by using wrapper classes's static toString method.
double i = 42.0;
String str = Double.toString(i);

Case of ascii format to string:
You can convert an ASCII code to String using toString() method of Character wrapper class as shown below:
 int i = 64;
 String aChar = new Character((char)i).toString();

Conversion from string:
Then in this case use parseWrapper method. Example:
For float :

String s = "31.2";
float f = Float.parseFloat(s);
