Convert the following while loop into a for loop.

int count = 0;

int numberOfCaptialLetters = 0;

String text = "Hello There How Are You?";

while(count < text.length()) {

char currentChar = text.charAt(count);

if(Character.isUpperCase(currentChar)) {

numberOfCaptialLetters++;

}

count++;

System.out.println("Total = " + numberOfCaptialLetters);

Write a Java program (code + screenshot of output) that takes student grades as double values and then outputs the following:

• The number of inputted grades

• The average

Sample run1:

Please input student grade or (-1) to stop: 20

Please input student grade or (-1) to stop: 80

Please input student grade or (-1) to stop: 80

Please input student grade or (-1) to stop: -1

The number of student grades: 3

The average is: 60.0

Sample run2:

Please input student grade or (-1) to stop: 50

Please input student grade or (-1) to stop: 100

Please input student grade or (-1) to stop: -1

The number of student grades: 2

The average is: 75.0

Sample run3:

Please input student grade or (-1) to stop: -1

No grades inputted
