Answer:
The code to this question can be given as:
Code:
public interface Test //define interface
{
public abstract Duration getDuration(); //define method
getDuration.
public abstract Result check(int a);
//define method
check .
public abstract double getScore();
//define method getScore.
}
Explanation:
In the above code, we define an interface that is "Test" inside an interface, we define three methods that can be defined as:
- First, we define a method that is "getDuration" that method returns Duration as an object.
- Second, we define a method that is "check" this method accepts an integer parameter that is a and return Result.
- The third method is "getScore" this method will return a double value.
import java.util.Scanner;
public class U2_L3_Activity_Four {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.println("Enter a sentence.");
String sent = scan.nextLine();
int count = 0;
for (int i = 0; i < sent.length(); i++){
char c = sent.charAt(i);
if (c != ' '){
count++;
}
else{
break;
}
}
System.out.println("The first word is " + count +" letters long");
}
}
We check to see when the first space occurs in our string and we add one to our count variable for every letter before that. I hope this helps!

Answer:
Option (e)
Explanation:
Option (e) is the answer. It indicates the exception thrown and displays it. It also indicates the place where the exception was thrown ( at what line of the code the exception was thrown )
Option (a) is false as the program which was terminated because of an exception which was not handled doesn't starts automatically.
Option (b) is false as it doesn't opens a dialogue box about running the program another time or anything. It just terminates because of the unhandled exception.
Option (c) is false as it doesn't saves all the output to a disk file called the "runStackTrace.txt".
Option (d) is false as it doesn't open a dialogue box. The program terminates because of the unhandled exception.
