Correct Option: A

"What will be the output of the following snippet: MOVE ZERO TO WS-COUNT IF WS-COUNT = 0 NEXT SENTENCE END-IF ADD +1 TO WS-COUNT. DISPLAY 'VALUE OF WS-COUNT: ' WS-COUNT "

  1. VALUE OF WS-COUNT: 0

  2. VALUE OF WS-COUNT: 1

  3. Compile error

  4. None of the above


Correct Option: A
  1. Compilation error, attempting to perform binary comparison on logical data type.

  2. Compilation and output of "We are equal 10".

  3. Compilation and output of "Not equal! 20".

  4. Compilation and output of "Not equal! 10".


Correct Option: D

What will be the output on compiling/running the following code? public class MyThread implements Runnable { String myString = "Yes "; public void run() { this.myString = "No "; } public static void main(String[] args) { MyThread t = new MyThread(); new Thread(t).start(); for (int i=0; i < 10; i++) System.out.print(t.myString); } }

  1. Compilation Error

  2. Prints : Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes and so on.

  3. Prints : No No No No No No No No No No and so on.

  4. Prints : Yes No Yes No Yes No Yes No Yes No and so on.

  5. The Output cannot be determined.


Correct Option: E

  1. True

  2. False


Correct Option: A

The modulus operator (%) in Java can be used only with variables of integer type.

  1. True

  2. False


Correct Option: B

AI Explanation

To answer this question, you need to understand the modulus operator (%) in Java and the types of variables it can be used with.

The modulus operator (%) in Java calculates the remainder of one number divided by another. While it is commonly used with integer types, it can also be used with other data types such as floating-point numbers (e.g., double and float).

So, the statement "The modulus operator (%) in Java can be used only with variables of integer type" is incorrect.

Let's go through each option to understand why it is correct or incorrect:

Option A) True - This option is incorrect because the modulus operator (%) in Java can be used with variables of other types, not just integer types.

Option B) False - This option is correct because the statement "The modulus operator (%) in Java can be used only with variables of integer type" is false.

The correct answer is B) False.

1) What will be the output of the following program?package chapters.chap02;public class Chap02 { public static void main(String[] args) { for (int i=0; i&lt;5; i++){ switch (i){ case 0: System.out.println(&quot;0&quot;); ++i; break; case -1: System.out.println(&quot;-1&quot;); break; case 2: System.out.println(&quot;2&quot;); i++; case 4: System.out.println(&quot;4&quot;); break; } } }}

  1. The program will not stop and it will run recursively upon execution

  2. The program will output '0 2 5 5'.

  3. The program will output '0 2 4 4'.

  4. The program will output '02 4 5'.


Correct Option: C

2) What will be the output of the following program when it is made to run with the options "java scjp5_0.chap07.Ques01 1"package scjp5_0.chap07;public class Ques01 { public static void main(String[] args) { for (int i = 0; i < 2; i ++){ try{ System.out.println(args[i]); }catch(Exception e){} } }}

  1. The program will output 'scjp5_0.chap07.Ques01 1'.

  2. The program will output 1.

  3. The program will output '1' and then will raise an ArrayIndexOutOfBoundsException.

  4. The program won't print anything but will raise an ArrayIndexOutOfBoundsException at run-time.


Correct Option: B

4) What is the result of compiling and running the following code? class VarArgOne { public static void printArgs(String s, Integer ... i, String s) { //line 1 for(int j : i) { //line 2 System.out.print(j + " " + s); //line 3 } } public static void main(String ... args) { //line 4 printArgs("exam", 12, 34, "scjp"); //line 5 } }

  1. Compilation fails due to error at line 1.

  2. Compilation fails due to error at line 2.

  3. Compilation fails due to error at line 4.

  4. Compilation fails due to error at both line 1 and line 4.
