System.out.println("Welcome to Java");
}
B:
for (int count = 0; count < 10; count++) {
System.out.println("Welcome to Java");
}
C:
for (int count = 1; count < 10; count++) {
System.out.println("Welcome to Java");
}

Question 2
Which of the following loops correctly computes 1/2 + 2/3 + 3/4 + ... + 99/100?
A:
double sum = 0;
for (int i = 1; i <= 99; i++) {
sum = i / (i + 1);
}
System.out.println("Sum is " + sum);
B:
double sum = 0;
for (int i = 1; i < 99; i++) {
sum += i / (i + 1);
}
System.out.println("Sum is " + sum);
C:
double sum = 0;
for (int i = 1; i <= 99; i++) {
sum += 1.0 * i / (i + 1);
}
System.out.println("Sum is " + sum);
D:
double sum = 0;
for (int i = 1; i <= 99; i++) {
sum += i / (i + 1.0);
}
System.out.println("Sum is " + sum);
E:
double sum = 0;
for (int i = 1; i < 99; i++) {
sum += i / (i + 1.0);
}
System.out.println("Sum is " + sum);
