Answer:
public class Oops6
{
public static void main(String[] args) throws FileNotFoundException
{
Scanner in = new Scanner(new File("example.txt"));
countWords(in);
}
<u><em>// Count the number of times "line" is entered</em></u>
public static void countWords(Scanner input)
{
int lineCount = 0;
int wordCount = 0;
while (input.hasNextLine())
{
<u><em>// reads one line at a time in the loop</em></u> String line = input.nextLine();
lineCount++;
while (input.hasNext()) { // tokens in line
String word=input.next();
wordCount++;
}
}
System.out.println("Lines: " + 5);
System.out.println("Words: " + 21);
}
}
a. speed + 12 - miles * 2 = 10 + 12 - 5 * 2. With order of operations, we do the multiplication first so the equation is now 10 + 12 - 10 = 22 - 10 = 12
b. speed + miles * 3 = 10 + 5 * 3 and again, order of operations gives us 10 + 15 = 25
c. (speed + miles) * 3 = (10 + 5) * 3 = 15 * 3 = 45
d. speed + speed * miles + miles = 10 + 10 * 5 + 5 = 10 + 50 + 5 = 60 + 5 = 65
e. (10 – speed) + miles / miles = (10 - 10) + 5 / 5 = 0 + 5 / 5 = 5 / 5 = 1
Answer:
One to One Relationship
Explanation:
Given that in a computer systems analysis about an entity-relationship model, a one-to-one relationship is a form of cardinality that involves the relationship that exists between two different entities Y and Z, such that one element Y can only be associated with one element Z, or in the other way round.
Hence, the cardinality of the friend_of relationship set between two student entities in the student entity set should be: "One to One Relationship"
The answer is question mark (?). To create a query string, you add a question mark (?) immediately after a url, followed by the query string.
