Listing 1 . File SampProg26.java.
/*File SampProg26.java from module 50 Copyright 1997, R.G.BaldwinWithout viewing the solution that follows, write a Java application that illustrates conversion from string tonumeric, similar to the atoi() function in C. The output from the program should be:The value of the int variable num is 3625 ===========================================================*/ class SampProg26{public static void main(String[] args){int num = new Integer("3625").intValue(); System.out.println("The value of the int variable num is " + num); }//end main()}//end class SampProg26

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
