Answer:
b. size
Explanation:
We can use the size() method of java.util.ArrayList to determine the size of an ArrayList in Java. The size() method of the ArrayList class returns an integer which is equal to the number of elements present in the ArrayList.
Below is an example code to illustrate the use of the size() method of the ArrayList:-
ArrayList<Integer> aList = new ArrayList<Integer>(5);
aList.add(25);
aList.add(2);
aList.add(5);
aList.add(22);
System.out.println("Size of the array list: " + aList.size());
This will print the size of the array list as 4 since we've added four numbers into the array list.
Answer:
fav_number=26
guess=0
while 0==0:
try:
guess=int(input('Enter your guess: '))
except:
print ('You have entered an invalid value.')
else:
if guess == fav_number:
break
elif guess>fav_number:
print ('Try a smaller number.')
elif guess<fav_number:
print ('Try a larger number')
Explanation:
define a variable fav_number and set it to number. write an infinite while loop to read input from user. In try block get input from user, if user enters invalid input code in except block will be executed. For valid input
- check if its greater than favorite number, if yes print try smaller number.
- check if its smaller than favorite number, if yes print try larger number.
- check if its equal to favorite number, break loop and exit
