A student is working on the pseudocode for converting measurements in feet and inches to only inches and produces the following steps: [login to view URL] the number of input feet [login to view URL] the number of input inches [login to view URL] inches = input inches 4. [login to view URL] Total Inches Which Pseudocode is missing for step 4? a. total inches = 12*input inches b. total inches = 12*input feet c. total inches = total inches + 12*input feet total inches = total feet 2. [login to view URL] speed = 2500; 2. 3. [login to view URL](“The speed is between 1000 and 5000 (both inclusive).”); 5.} Which piece of code, if placed on line 3, will enable the program to work as expected? If (speed > 1000 and speed < 5000) { if (speed >= 1000 && speed <= 5000){ if (speed > 1000 && speed < 5000) if (1000< speed < 5000) 3. 1. int total = 0; 2. for (int i = 0; i<50; I +=2) { 3. total +=i; 4. } 5. [login to view URL](total); Which block can replace lines 2 through 4 to produce the same result? a. while(i<50){ total +=i; } b. int i=0; while (i<50){ \ total +=i; } c. int i=0; while (i<50){ total +=i; i+=2; } d. while (int I < 50; i +=2){ total +=i; } 4. [login to view URL] i=0; [login to view URL] (i<10){ 3. 4.} Which modification will prevent the infinite loop? a. Replace the code on line 2 with the following code: do { line 4: } while (i<10); b. Replace the code on line 1 with the following code: int i=-1; c. Add the following code to line 3: i++; d. Replace the code on line 2 with the following code: while (i<=10){ 5. [login to view URL] [][] numbers = { 2. {6,7,8}, 3. {10,11,12} 4.}; 5. [login to view URL] (int i=0; I < [login to view URL]; i++) { 7. 8. [login to view URL](numbers[i][j] + “ “); 9. } 10. } Which line of code, if placed on line 7, will provide the output 6 7 8 9 10 11 12? [login to view URL] (int j=0; j<i; j++){ [login to view URL] (int j=0; j < numbers[i].length; j++){ [login to view URL] (int j=0; j<1; j++){ [login to view URL] (int j=i; j<numbers[i].length; j++){ 6. 1. try{ 2. …..some code.... 3. } catch (IOException e){ 4. [login to view URL](“Caught IOException”); 5. } catch (Exception e) { 6. [login to view URL](“Caught Exception”); 7. } finally ( 8. [login to view URL](“Done!”); 9. } What is the program output if line 2 causes an IOException? a. Caught IOException Done! b. Caught IOException Caught Exception Done! c. Caught Exception Done! d. Done! 7. A developer writes a method that requires a positive integer value. Which option provides the codes users with the most error recovery posibilities? a. Throw new Exception(“input must be positive”); b. [login to view URL](“iinput must be positive”); c. throw new IllegalArgumentException(); d. throw new IllegalArgumentException(“Input must be positive!”); 8. int a = 10; int b = 30; b = a; b = a+b; [login to view URL](a + “ “ + b); What is the output on the screen/ a. 10 30 b. 10 40 c. 10 20 d. 10 10 9. 1. double a = 15.6; 2. int b=3; 3. int c=(int) a/b; What is the final value of c? a. The code will not compile, error on line 3 b. 5.2 c. 5 d. 3.2 10. int x=15; int y=2; x=x-y; int z=x*y; [login to view URL](x+” “+y+” “+z); If the code is executed, what will be the output on the console? a. 15 2 17 b. 13 26 30 c. 13 2 26 d. 2 15 30
