◍ Which is the hexadecimal representation of the binary number 0010 110
1011 1111?.
Answer: 2CBFEach 4 digit binary number translates to a single hexadecimal
digit. Any value higher than 9 will result in an uppercase letter starting from
A.
◍ What are the binary numbers up to the 8th place value?.
Answer: 128 64 32 16 8 4 2 1You can solve this for any amount of place
values by using the equation 2^n, where n is the place value. You start with
0 and work your way up to the last place value. This works for other bases
such as base 4 as well, just replace the 2 with the new base number.
◍ Consider the following code segment.System.out.print("Hello
System.out.println");System.out.print("!!!");What is printed as a result of
executing the code segment?A) Hello!!!B) Hello System.out.println!!!C)
Hello !!!D) Hello System.out.println !!!E) Nothing is printed because the
text "System.out.println" cannot appear inside a print statement..
Answer: B) Hello System.out.println!!!

is printed as a result of executing the code
segment?A)**********B)**********C)**********D)**********E)**********.
Answer: D)**********
◍ What is the output of the following program
statement?System.out.println("Total: " + 8 + 3);.
Answer: Total: 83Because the statement starts with a String, the numbers
are simply concatenated, not added together.

3;System.out.println(a + b / c * 2);What is printed as a result of executing
this code?A) 2B) 6C) 8D) 9E) 14.
Answer: D) 9
◍ How many different values can be represented in 7 bits?.
Answer: 128You can figure this out for any amount of bits by the equations
2^n, where n is the number of bits.
◍ Consider the following code segment.double x = (int) (5.5 - 2.5);double y =
(int) 5.5 - 2.5;System.out.println(x - y);What is printed as a result of
, executing the code segment?A) -1.0B) -0.5C) 0.0D) 0.5E) 1.0.
Answer: D) 0.5
◍ What is the decimal (base 10) value of the base 4 number 123?.
Answer: 27Base 4 place values can be found similarly to binary, where you
use 4^n and then solve the number, which would be 1*16 + 24 + 3*1 = 27.
◍ Java is platform independent because of the....
Answer: JVM.
◍ Consider the following code segment.int x = 5;x += 6 * 2;x -= ;What
value is stored in x after the code segment executes?A) -1.5B) 1C) 9D)
15.5E) 16.
Answer: E) 16
◍ What is a JVM?.
Answer: A Java Virtual Machine. Each platform has its own JVM that
translates bytecode for that platform.
◍ Consider the following code segment.System.out.print(*); // Line
1System.out.print("*"); // Line 2System.out.println( ); // Line
3System.out.println("*"); // Line 4The code segment is intended to produce
the following output, but may not work as intended.***Which line of code,
if any, causes an error?A) Line 1B) Line 2C) Line 3D) Line 4E) The code
segment works as intended..
Answer: A) Line 1

I. (double) + 3I
I. (double) () + 3II
I. (double) ( + 3)A) I onlyB) III onlyC) I and II onlyD) II and III onlyE)
I, II, and III.
Answer: A) I only
◍ What kind error occurs when you use the wrong formula to calculate the
area of a circle?.
Answer: Logic error. This is because the machine compiles and has a valid
