In this HackerRank Java Int to String problem in java programming language You are given an integer n, you have to convert it into a string. If your code successfully converts n into a string s the code will print “Good job”. Otherwise it will print “wrong answer”.
HackerRank Java Int to String problem solution.
import java.util.*;
import java.security.*;
public class Solution {
public static void main(String[] args) {
DoNotTerminate.forbidExit();
try {
Scanner in = new Scanner(System.in);
int n = in .nextInt();
in.close();
//String s=???; Complete this line below
//Write your code here
String s = Integer.toString(n);
if (n == Integer.parseInt(s)) {
System.out.println("Good job");
} else {
System.out.println("Wrong answer.");
}
} catch (DoNotTerminate.ExitTrappedException e) {
System.out.println("Unsuccessful Termination!!");
}
}
}
//The following class will prevent you from terminating the code using exit(0)!
class DoNotTerminate {
public static class ExitTrappedException extends SecurityException {
private static final long serialVersionUID = 1;
}
public static void forbidExit() {
final SecurityManager securityManager = new SecurityManager() {
@Override
public void checkPermission(Permission permission) {
if (permission.getName().contains("exitVM")) {
throw new ExitTrappedException();
}
}
};
System.setSecurityManager(securityManager);
}
}
