Answer:
JTextField
Explanation:
JTextField is a Swing control which can be used for user input or display of output. It corresponds to a textfield and can be included with other controls such as JLabel, JButton,JList etc. on a comprehensive user interface which is application dependent. JTextField supports a read-write mode where the user can enter a value and it also supports a read-only mode which can be used to display non-editable output to the user.
By looking at your code, it seems like you're trying to let the user enter positive numbers until the user enters a negative number. To achieve this, you need to indent int(input("Enter a number, negative to stop")) inside the loop.
The second answer choice is correct.

Answer:
The complete method is as follows:
public static int divBySum(int[] arr, int num){
int sum = 0;
for(int i:arr){
if(i%num == 0)
sum+=i;
}
return sum;
}
Explanation:
As instructed, the program assumes that arr has been declared and initialized. So, this solution only completes the divBySum method (the main method is not included)
This line defines the method
public static int divBySum(int[] arr, int num){
This line declares and initializes sum to 0
int sum = 0;
This uses for each to iterate through the array elements
for(int i:arr){
This checks if an array element is divisible by num (the second parameter)
if(i%num == 0)
If yes, sum is updated
sum+=i;
}
This returns the calculated sum
return sum;
}
