String Conversion

• Conversion from primitive type to String

  • Done through Wrapper Classes which override the toString() method

  • Syntax

    ```java
    Integer a = 130;
    String s = a.toString();
    ```
    

• Conversion from String to primitive type

  • Each wrapper class has a parse method → parseXXX()

  • Syntax

    ```java
    int a = Integer.parseInt(s);
    byte b = Byte.parseByte(s);
    
    //Exception
    //Since String is made of chars anyway 
    //considering the String is made of a single character
    char c = s.charAt(0)
    
    ```
