"Consider the following code snippet: int number = 0; Scanner in = new Scanner(System. in); System. out. print(""Enter a number: ""); number = in. nextInt(); if (number > 30) { . . . } else if (number > 20) { . . .. } else if (number > 10) { . . . } else { . . . } Assuming that the user input is 40, which block of statements is executed? a. if (number > 30) { . . .}
b. else if (number > 20) { . . .}
c. else if (number > 10) { . . .}
d. else { . . .}

if (number > 30) {. . .}

Explanation:

This code block uses a simple if-elseif-else control structure to do a comparison on a value.  In this type of control structure, each operation of control is check until the correct condition is met, and once the code executes, it exits the control structure, never touching the remainder of the structure.

In this example, we are fortunate that the value triggers the first part of the control structure with if (number > 30) and will execute that section of code.  Once the code finishes, it will exit the structure, never making it to the other 3 control conditions.

Cheers.
