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".

Answer:
public static int greaterThanInt(int n){
return n+10;
}
Explanation:
This is a very simple method in Java. it will accept an argument which is an integer n and return n+10 since the question requires that an arbitrary integer greater than n be returned adding any int value to n will make it greater than n.
A complete java program calling the method is given below:
<em>import java.util.Scanner;</em>
<em>public class ANot {</em>
<em> public static void main(String[] args) {</em>
<em> Scanner in = new Scanner(System.in);</em>
<em> System.out.println("Please enter an integer");</em>
<em> int n = in.nextInt();</em>
<em> int greaterInt = greaterThanInt(n);</em>
<em> System.out.println("You entered "+n+", "+greaterInt+" is larger than it");</em>
<em> }</em>
<em> public static int greaterThanInt(int n){</em>
<em> return n+10;</em>
<em> }</em>
<em>}</em>
