Question 11 pts

A compile-time error occurs when

Group of answer choices

c. there’s a syntax error in a Java statement

a. the Java compiler can’t be located

b. bytecodes can’t be interpreted properly

c. there’s a syntax error in a Java statement

Answer is c

Compile time error occurs during the compiler check the program compiled. Compiler will terminate the program with error when a syntactical error is encountered.

An error that lets the application run but produces the wrong results is known as a

Group of answer choices

d. syntax error

c. logic error

a. runtime error

b. user error

Answer is c (logical error)

In the case where the application runs without both compile time error and run time error and produces the wrong results then the program have logical errors.

Question 31 pts

What is the range of values that x can hold after this statement is executed?

double x = Math.random() * 10 + 100;

Group of answer choices

b. 100 <= x < 110

c. 100 <= x < 200

a. 100 <= x < 101

d. 100 <= x < 1100

Answer is b (100 <= x < 110)

Math.random() will generate values from 0 inclusive to 1 exclusive.
Then Math.random()*10 will generate values from [0,10)
Add 100 to above result will yield [100,110)
which means values from 100 inclusive to 110 exclusive.

Question 41 pts

If a = 5, b = 2, and c = 10, what is the value of c after the following statement is executed?

c = c + a * b – 5;

Group of answer choices

a. -45

d. None of the above

b. 15

c. 25

Answer is b (15)

first multiplication happes which yields c+10-5
which will result in 15

Assume that before the following code is executed, the value of totalOne is 6.728, the value of totalTwo is 116, and both are BigDecimal objects. What is the value of totalFinal after the code is executed?

totalOne = totalOne.setScale(2, RoundingMode.HALF_UP);

BigDecimal totalFinal = totalTwo.add(totalOne);

Group of answer choices

d. 123

b. 122.72

a. 122.728

c. 122.73

Answer is c (122.73)

FirstLine will change the value of totalOne from 6.728 to 6.73

Second line will add up the values totalOne and totalTwo i.e 6.73 + 116 = 122.73
