Question:

Consider the following program:

public class DataTypesExample {
  public static void main(String[] args) {
    int numStudents = 35;
    double averageScore = 83.45;
    char grade = 'A';
    boolean passed = true;

    System.out.println("Number of students in the class: " + numStudents);
    System.out.println("Average score in the class: " + averageScore);
    System.out.println("Grade of the student: " + grade);
    System.out.println("Did the student pass the class? " + passed);
  }
}

What will be the output of the above program?

  1. Number of students in the class: 35 Average score in the class: 83.45 Grade of the student: A Did the student pass the class? true

  2. Number of students in the class: 35.0 Average score in the class: 83.45 Grade of the student: A Did the student pass the class? true

  3. Number of students in the class: 35 Average score in the class: 83.45 Grade of the student: 65 Did the student pass the class? true

  4. Number of students in the class: 35 Average score in the class: 83.45 Grade of the student: A Did the student pass the class? false

  5. None of the above

Answer:

The correct answer is option 1:

Number of students in the class: 35 Average score in the class: 83.45 Grade of the student: A Did the student pass the class? true

Explanation:

  • The variable numStudents is assigned the value 35, which is an int data type.
  • The variable averageScore is assigned the value 83.45, which is a double data type.
  • The variable grade is assigned the value 'A', which is a char data type.
  • The variable passed is assigned the value true, which is a boolean data type.

In the program, we use the System.out.println() method to print the values of these variables along with some additional text. The output will be displayed as follows:

Number of students in the class: 35
Average score in the class: 83.45
Grade of the student: A
Did the student pass the class? true

Therefore, option 1 is the correct answer.
