How many times does the following loop execute?int upperCaseLetters = 0;String str = "abcdEfghI";boolean found = false;for (int

damaskus [11]

Answer:

Five times

Explanation:

Given the codes as follows:

int upperCaseLetters = 0;
String str = "abcdEfghI";
boolean found = false;
for (int i = 0; i < str.length() && !found; i++)
{
char ch = str.charAt(i);
if (Character.isUpperCase(ch))
{
found = true;
}
}

The for loop will stop when the first uppercase letter is found in the str. This condition is set in the for loop condition ( i < str.length() && !found)

Since the the first upper case letter is the fifth character in the given str, the for loop will run for five rounds. In the fifth round the condition in the if statement (Line 9) will be evaluated to true and then set the true value to found variable (Line 11). This will terminate the loop in the next iteration.

xz_007 [3.2K]

Answer: B) Shape is a base class, and circle and square are derived classes of Shape.

Shape is a base class because circle and squares are the shapes so these are the derived class of the shape, which is inherited by the shape like circle and square. As, the base class (shape) is the class which are derived from the other classes like circle and square and it facilitates other class which can simplified the code re-usability that is inherited from the base class. Base class is also known as parent class and the super class.
