<h2>Answer:</h2>

14.0

<h2>Explanation:</h2>

Using the level of precedence in Java,

From left to right;

(i) the first division operation will be done.

(ii)followed by the second division operation.

(iii)followed by the first multiplication operation.

(iv)followed by the third division operation.

(v)followed by the second multiplication operation.

(vi) followed by the first addition operation.

(vii)lastly followed by the second addition operation.

=================================================

Taking the steps above one after the other;

<em>(i) the first division operation will be done (i.e 19 / 2)</em>

=> Integer division in Java gives an integer result. Therefore, 19 / 2 = 9.5 will give 9.

So,

=><em> </em><u>19 / 2</u> / 2.0 + 2.5 * 6 / 2 + 0.5 * 4

=> 9 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4

<em>(ii)followed by the second division operation. (i.e 9 / 2.0)</em>

=> From the result from step (i), the second division operation is now 9 / 2.0.

=> 9 / 2.0 = 4.5

So,

=> <u>9 / 2.0</u> + 2.5 * 6 / 2 + 0.5 * 4

=> 4.5 + 2.5 * 6 / 2 + 0.5 * 4

<em>(iii)followed by the first multiplication operation. (i.e 2.5 * 6)</em>

=> The first multiplication operation is given by 2.5 * 6

=> 2.5 * 6 = 15.0

So,

=> 4.5 + <u>2.5 * 6</u> / 2 + 0.5 * 4

=> 4.5 + 15.0 / 2 + 0.5 * 4

<em>(iv)followed by the third division operation. (i.e 15.0 / 2)</em>

=> The third division operation is given by 15.0 / 2

=> 15.0 / 2 = 7.5

So,

=> 4.5 + <u>15.0 / 2</u> + 0.5 * 4

=> 4.5 + 7.5 + 0.5 * 4

<em>(v)followed by the second multiplication operation. (i.e 0.5 * 4)</em>

=> The second multiplication operation is given by 0.5 * 4

=> 0.5 * 4 = 2.0

So,

=> 4.5 + 7.5 + <u>0.5 * 4</u>

=> 4.5 + 7.5 + 2.0

<em>(vi) followed by the first addition operation. (i.e 4.5 + 7.5)</em>

=> The first addition operation is given by 4.5 + 7.5

=> 4.5 + 7.5 = 12.0

So,

=> <u>4.5 + 7.5</u> + 2.0

=> 12.0 + 2.0

<em>(vii) lastly followed by the second addition operation. (i.e 12.0 + 2.0)</em>

=> The second addition operation is given by 12.0 + 2.0

=> 12.0 + 2.0 = 14.0

So,

=> <u>12.0 + 2.0</u>

=> 14.0

<em>Therefore, 19 / 2 / 2.0 + 2.5 * 6 / 2 + 0.5 * 4 = 14.0</em>

In Java, the order of precedence for arithmetic operators is;

=> /, * and %

=> followed by + and -

The ____ operator executes one of two expressions based on the results of a conditional expression. Group of answer choices

Mars2501 [29]

Corrected or Complet Question

The ____ operator executes one of two expressions based on the results of a conditional expression.

a. .

b. ( )

c. ,

d. ?:

Answer:

(d) ? :

Explanation:

The ternary operator (? :) is an operator that executes one out of two expressions based on the results of a conditional expression. It is a faster or shorthand way of writing an if ... else statement. The operator checks the conditional expression and depending on whether it is true or false, one of its two statements will be executed. For example:

String correct = (4 < 5) ? "yes" : "no" ;

In the code above,

i. the conditional statement is (4 < 5) and this will be tested for to return true or false.

ii. the first expression (the one after the ?) is "yes" which will be executed if the conditional statement returns true.

iii. and the second expression (the one after the : ) is "no" which will be executed if the conditional statement returns false.

Therefore, since the conditional expression returns true for 4 < 5, the first expression will be executed. i.e "yes". This means that the String variable <em>correct </em> will have a value of "yes".
