Reason (R): Array will always begin with the 0 th subscript. a. Both Assertion (A) and Reason (R) b. Both Assertion (A) and Reason (R) are true and Reason (R) is a correct are true and Reason (R) is not a explanation of Assertion (A) correct explanation of Assertion(A) c. Assertion (A) is true and Reason (R) d. Assertion (A) is false and Reason (R) is false is true Choose the correct way to initialize a two-dimensional array in Java? a. int a[][] myArray = {{1,2},{3,4}}; b. int a[2][2] = {{1,2},{3,4}}; c. int a[2][2] myArray; d. None of above myArray[0][0]=1; myArray[0][1]=2; myArray[1][0]=3; myArray[1][1]=4; Which of these is an incorrect array declaration? a. int arr[] = new int[5] b. int [] arr = new int[5] c. int arr[] = int [5] new d. All are correct What is the output of the Java code given below? String color[]={ blue , red , violet }; System.out.println(color[2].length()); a. 6 b. 5 c. 3 d. Error Predict the output of the following code snippet: String P = "20", Q ="24"; int a = Integer.parseInt(P); int b = Integer.valueOf(Q); System.out.println(a+""+b); a. 20 b. 24 20 c. 2024 d. 24 Cell number of a dimensional array is also known as a. Packets b. Blocks c. Subscripts d. compartments Read the following text and choose the correct answer: It is also an infixed or unknown iterative loop i.e., the user may not be aware of the number of times the iterations will take place. In this loop, the condition is checked at first before entering into the loop. Which of the following options best describes the above given text? a. for loop b. do-while loop c. while loop d. switch construct What is the final value stored in variable x? double a=-8.35 double x=Math.abs(Math.floor(a)); a. 9.0 b. 7.0 c. 6 d. 7 [9] Q.B. 1. 2. 3.
