Linkedin Java Assessment Questions and Answers Old

Q1. Given the string “strawberries” saved in a variable called fruit, what would “fruit.substring(2, 5)” return?
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?
Q3. Given the following definitions, which of these expressions will NOT evaluate to true?
boolean b1 = true, b2 = false; int i1 = 1, i2 = 2;

    }
}

String str = “”abcde””;
str.trim();
str.toUpperCase();
str.substring(3, 4);
System.out.println(str);
Q8. What is the result of this code?
 
1: class Main {
2:   public static void main (String[] args){
3:     System.out.println(print(1));
4:   }
5:   static Exception print(int i){
6:       if (i>0) {
7:          return new Exception();
8:       } else {
9:          throw new RuntimeException();
10:      }
11:  }
12: }
Q9. Which class can compile given these declarations?
 
1: interface One {

    publc void method() {
        super.One.method();
  } }
    publc void method() {
        One.method();
  } }
}
    publc void method() {
        One.super.method();
  } }
Q10. What is the output of this code?
 
1: class Main {
2:  public static void main (String[] args) {
3:      List list = new ArrayList();
4:      list.add(“hello”);

6:      System.out.print(list.get(0) instanceof Object);
7:      System.out.print(list.get(1) instanceof Integer);
8:  }
9: }
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: }
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!”;

13: }
Q13. Given this code, which command will output “2”?
class Main {
    public static void main(String[] args) {
        System.out.println(args[2]);
    }
}
Q14. What is the output of this code?
class Main {
    public static void main(String[] args){
        int a = 123451234512345;
        System.out.println(a);
    }
}
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)
            + message.substring(12, 6);
        System.out.println(newMessage);
    }
}

        }
    }
}

    System.out.print(“Hello World”);

}finally{
    System.out.println(“!”)
}
Q27. Which statement is NOT true?
Q28. What will this program print out to the console when executed?
