Java uses the parseint () method in the integer class to convert a string to a base data type

Import java.util.*;p ublic class systeminfo{public static void Main (string[] args) {Properties sp = System.        GetProperties ();        Enumeration E = Sp.propertynames ();               while (E.hasmoreelements ()) {string key = (string) e.nextelement ();         System.out.println (key+ "=" +sp.getproperty (key)); }    }}
