Given a integer, convert to String, using String Builder class. No error checking needed on input integer, However do read in the input integer using Scanner API. This program requires you to use a loop.

The program in Java will be:

/ / Java program to demonstrate working parseInt ()

public class GFG

{

public static void main (String args[])

{

int decimalExample = Integer. parseInt ("20");

int signedPositiveExample = Integer. parseInt ("+20");

int signedNegativeExample = Integer. parseInt ("-20");

int radixExample = Integer. parseInt ("20",16);

int stringExample = Integer. parseInt ("geeks",29);

/ / Uncomment the following code to check

/ / NumberFormatException

/ / String invalidArguments = "";

/ / int emptyString = Integer. parseInt (invalidArguments);

/ / int outOfRangeOfInteger = Integer. parseInt ("geeksforgeeks",29);

/ / int domainOfNumberSystem = Integer. parseInt ("geeks",28);

System. out. println (decimalExample);

System. out. println (signedPositiveExample);

System. out. println (signedNegativeExample);

System. out. println (radixExample);

System. out. println (stringExample);

}
