Of the following, if statements, which one correctly executes three instructions if the condition is true
If (x < 0) { a = b * 2; y = x; z = a – y; }
If{ (x < 0) a = b * 2; y = x; z = a – y ; }
{ if (x < 0) a = b * 2; y = x; z = a – y; }
If (x < 0) a = b * 2; y = x; z = a – y;
Which of the sets of statements below will add 1 to x if x is positive and subtract 1 from x if x is negative but leave x alone if x is 0?
If (x > 0) x++; else x--;
If (x == 0) x = 0; else x++; x--;
If (x > 0) x++; else if (x < 0) x--;
X++; x--;
_______ is the process of finding errors and fixing them within a program.
Compiling
Executing
Debugging
Scanning
Compare the following two if statements and select, which answer best, summarizes each line of code. String name1, name2; int guess, answer; if (name1.equals(name2)) if (guess == answer)
The first if statement will compare the numerical value of the two names entered to see if they are equal and the second if statement will also compare the numerical values to see if they are equal
The first if statement will not work correctly due to string values being used, the second if statement will correctly compare the variables guess and answer
The first if statement will compare the two string values to see if they are equal and the second will compare the two integer values to see if they are equal.
The first if statement should read if (name1 == name2) in order to properly compare the values and the second if statement will compare the numerical values to see if they are equal.

Esc
Ctrl - C
Kim has just constructed her first for loop within the Java language. Which of the following is not a required part of a for loop?
Initialization
Condition
Variable
increment
Analyze the following error that was received when Scott tried to compile his java program named average. Average.java:14: 'else' without 'if' else ^ Which of the following could have resulted in the error being generated?
Scott used an infinite loop within his program
Scott placed a semicolon at the end of an If statement
Scott placed a semicolon at the end of an If statement
Scott omitted a line of code below the If statement such as a System.out.pritnln or a Keybaord.readInt();
A technique used by codes to convert an analog signal into a digital bit stream is known as
Pulse code modulation
Pulse stretcher
Query processing
Queue management

Jay is considering adding a repetition statement within his Java programming final project. Jay is unsure of the number of times each loop needs to execute. Analyze the conditional statements below and select which statement best fits the need identified by Jay within his programming.
While loop
If-Else
For loop
Switch statement
Kevin has implemented a While loop within his Java program. Assess the code statement below and select which answer best summarizes the output Kevin will experience once the while statement is executed. Int count = 1; while (count <=25) { System.out.println (count); Count = count –1; } System.out.println (“Done”);
The while loop will execute 25 times and print the numbers 1 thru 25 and finish with the printing of Done.
The while loop will execute 25 times and print the numbers 25 down to 1 and finish with the printing of Done.
The while statement will not function correctly due to a missing semicolon(;) after the statement while (count <=25)
The while statement will execute by counting down from 1 until infinity and result in an infinite loop.
The protocol data unit (PDU) for the application layer in the Internet stack is
Message
Segment
Frame
Datagram
Score =Keyboard.readInt(); while (score != -1) { System.out.println (“The score is” + score); score =Keyboard.readInt(); } USER INPUT = -1, predict what will happen after the user input is accepted into the java program.
The while statement will continue to ask the user to enter a score and then print out the score that has been received.
The while loop will execute an infinite number of times because the program statement can never be false
The while statement will never print the statement “The score is” because the condition present within the while will be false on the first time through.
The while statement will function until a value other than –1 is entered.
Which of the following protocols is an application layer protocol that establishes, manages and terminates multimedia sessions ?
Session Maintainence Protocol
Session Initiation Protocol
Real-Time Streaming Protocol
Real-Time Transport Control Protocol
