Answer 1

The correct answer for the given question is option(A) i.e Throws an exception .

Step-by-step explanation:

following are the code in java language

public class Main

{

public static void main (String[]args)

{

int userNumber =14;

String userEntry="two";

userNumber= Integer.parseInt(userEntry);

System.out.println(userNumber);

}

}

The main class throws an EXCEPTION java.lang.NumberFormatException
