Task #1 – Desk Checking

Assume that any variables in the following code snippets have been properly declared.

Can you find the errors (if any) in the following statements and if so, what are they?

1) if (x == 1)

                                y=2;

                else if (x==2);

                                y=3;

2) Count = 0;

if (COUNT == 0)

Count = COUNT + 1;

3) if (average = 100)

System.out.println(“You have a perfect grade”);

4) X==4;

X = X/2;

System.out.println(“the answer is “ + X);

5)   X = A + B / C – D * E – 7 * F;

Solution

Question 1:

Answer: Removed sem colon from else if (x==2);

1) if (x == 1)

y=2;

else if (x==2)

y=3;

Question 2:

Answer:

Count = 0;

if (Count == 0)

Count = Count + 1;

Question 3:

Answer:

if (average == 100)

System.out.println(“You have a perfect grade”);

Question 4:

Answer:

X=4;

X = X/2;

System.out.println(“the answer is “ + X);

Question 5:

Answer:

X = (A + B) / (C – D * E – 7 * F);
