The event is called keypress, usually the code is referred to as callback.
Answer:
<em>(c) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 7 in a string whose last element is at index 6.</em>

Explanation:
Given
printAllCharacters method and printAllCharacters("ABCDEFG");
Required
What happens when x < str.length() is changed to x <= str.length()
First, we need to understand that str.length() gets the length of string "ABCDEFG"
There are 7 characters in "ABCDEFG".
So: str.length() = 7
The first character is at index 0 and the last is at index 6
Next, we need to simplify the loop:
for (int x = 0; x< str.length(); x++) means for (int x = 0; x< 7; x++)
The above loop will iterate from the character at the 0 index to the character at the 6th index
while
for (int x = 0; x<=str.length(); x++) means for (int x = 0; x<=7; x++)
The above loop will iterate from the character at the 0 index to the character at the 7th index
Because there is no character at the 7th index, the loop will return an error
Hence: (c) is correct
Answer:
Python code given below
Explanation:
def calculate_storage(filesize):
block_size = 4096
full_blocks = filesize // block_size
partial_block = filesize % block_size
if partial_block > 0:
return (full_blocks + 1) * block_size
return filesize
print(calculate_storage(1))
print(calculate_storage(4096))
print(calculate_storage(4097))
Janice can actually used both knowledge as an advantage. She can use her background in farming while learning more about medicine. In such a way, she can have a strong advantage in medicinal farming - like learn ways to create good and effective drugs from plants, etc.
Answer:
B. until another thread issues a notify on the semaphore.
Explanation:
A semaphore is a variable that is shared between threads and is not negative. It also acts as a calling mechanism that uses two atomic operations wait and signal for synchronization of processes.
A thread that is waiting for a process can be signaled by another thread.
A semaphore puts a thread to sleep until another thread issues a notify on the semaphore.
The wait operation will get a semaphore or otherwise wait if the busy S semaphore is available.
The signal operation will release a semaphore or wake a process if there is a thread waiting for S.
