Question

The following for loop executes 26 times.

for (int i = 0; i <= 50; i = i + 2)

System.out.println(i);

True

False

  

Suppose that you have the following code.

int num = 5;

if (num >= 5)

     System.out.println(num);

else

     System.out.println(num + 5);

The output of this code is 10.

True

False

Suppose x = 18.9. The output of the statement -- System.out.println((int(x) % 3); is 1.

True

False

  

The expression !(x < 0) is true only if x is a positive number.

True

False

If the initial condition of any while loop is false, the statements within the loop will still execute once.

True

False

  

If the output file does not exist you will get a FileNotFoundException.

True

False

The output of the Java code (Assume all variables are properly declared.)

System.out.print("St");

for (int count = 5; count <= 3; count--)

System.out.print('o');

System.out.println('p');

is: Stoop

True

False

Given

int one;

double two;

boolean four;

which of the following assignment statements are valid?

(i) xx = 7 + 3 % 4;

(ii) 2.3 + 3.5 = two;

(iii) four = (2 <= 3);

Only (i) is valid

(i) and (ii) are valid

(ii) and (iii) are valid

only (iii) is valid

Only (i) is valid

(i) and (ii) are valid

(ii) and (iii) are valid

only (iii) is valid
