Q1. Given the string "strawberries" saved in a variable called fruit, what would "fruit.substring(2, 5)" return?
  • rawb
  • raw <<<<---Correct
  • awb
  • traw
Reasoning: The substring method is accepting two arugments. The first argument being the index to start(includes that char at 2) and the second the index of the string to end the substring(excludes the char at 5). Strings in Java are like arrays of chars. Therefore the method will return "raw" as those are the chars in indexs 2,3, and 4. You can also take the ending index and subtract the beginning index from it, to determine how many chars will be included in the substring (5-2=3).

Q2. How can you achieve runtime polymorphism in Java?
  • method overloading
  • method overrunning
  • method overriding <<<<--- Correct
  • method calling
Q3. Given the following definitions, which of these expressions will NOT evaluate to true?

  • (i1 | i2) == 3
  • i2 && b1 <<<<---Correct
  • b1 || !b2

5: interface Two {
6:      default void method () {
7:          System.out.println(""One"");
8:      }   }
 
  •  class Three implements One, Two {
    publc void method() {
        super.One.method();
  } }
  •   class Three implements One, Two {
    publc void method() {
        One.method();

Q11. Given the following two classes, what will be the output of the Main class?

package mypackage;
public class Math {
    public static int abs(int num){
        return num<0?-num:num;
    }
}
package mypackage.elementary;
public class Math {
    public static int abs (int num) {
        return -num;
    }
}
1: import mypackage.Math;
2: import mypackage.elementary.*;

3: class Main {
4:  public static void main (String args[]){
5:      System.out.println(Math.abs(123));
6:  }
7: }

  • Lines 1 and 2 generate compiler erros due to class name conflicts.
  • "-123"
  • It will throw an exception on line 5.
  • "123" <--- Correct // The answer is "123". The abs() method evaluates to the one inside mypackage.Math class.


Q12. What is the result of this code?
1: class MainClass {
2:  final String message(){
3:      return "Hello!";
4:  }
5: }

6: class Main extends MainClass {
7:  public static void main(String[] args) {
8:      System.out.println(message());
9:  }

10: String message(){
11:     return "World!";
12:  }
13: }

  • It will not compile because of line 10. <--- Correct
  • "Hello!"
  • It will not compile because of line 2.
  • "World!"

Q13. Given this code, which command will output "2"?
class Main {
    public static void main(String[] args) {
        System.out.println(args[2]);
    }
}


  • java Main 1 2 "3 4" 5
  • java Main 1 "2" "2" 5 <--- Correct
  • java Main.class 1 "2" 2 5
  • java Main 1 "2" "3 4" 5


Q14. What is the output of this code?
class Main {
    public static void main(String[] args){
        int a = 123451234512345;
        System.out.println(a);
    }
}

  • "123451234512345"
  • Nothing - this will not compile. <<<<---Correct
  • a negative integer value
  • "12345100000"

Reasoning: The int type in Java can be used to represent any whole number from -2147483648 to 2147483647. Therefore this code will not compile as the number assigned to 'a' is larger than the int type can hold.

Q15. What is the output of this code?
class Main {
    public static void main (String[] args) {
        String message = "Hello world!";
        String newMessage = message.substring(6, 12)

        System.out.println(newMessage);
    }
}

  • The code does not compile.
  • A runtime exception is thrown <<<<---Correct
  • "world!!world"
