Cuestionario 19. 1Z0-808

Given:

class MarksOutOfBoundsException extends IndexOutOfBoundsException {
}
 
public class GradingProcess {
 
    void verify(int marks) throws IndexOutOfBoundsException {
        if (marks > 100) {
            throw new MarksOutOfBoundsException();
        }
        if (marks > 50) {
            System.out.print("Pass");
        } else {
            System.out.print("Fail");
        }
    }
 
    public static void main(String[] args) {
        int marks = Integer.parseInt(args[2]);
        try {
            new GradingProcess().verify(marks);
        } catch (Exception e) {
            System.out.print(e.getClass());
        }
    }
}

And the command line invocation:

java GradingProcess 89 50 104

What is the result?

Given:

interface Pet {
}
 
class Dog implements Pet {
}
 
public class Beagle extends Dog {
}

Which three are valid?

Given the code fragment:

StringBuilder sb = new StringBuilder() ;
sb.append("world");

Which code fragment prints Hello world?

Given the code fragment:

class Student{
    String name;
    int age;
}

And,

public class Test{
    public static void main(String[] args){
        Student s1 = new Student();
        Student s2 = new Student();
        Student s3 = new Student();
        s1 = s3;
        s3= s2;
        s2 = null;
    }
}

Which statement is true?

Given the code fragment:

class Student {
 
    int rollnumber;
    String name;
    List cources = new ArrayList();
    
    // insert code here
 
    public String toString() {
        return rollnumber + " : " + name + " : " + cources;
    }
}

And,

public class Test {
 
    public static void main(String[] args) {
        List cs = new ArrayList();
        cs.add("Java");
        cs.add("C");
        Student s = new Student(123, "Fred", cs);
        System.out.println(s);
    }
}

Which code fragment, when inserted at line // insert code here, enables class Test to print 123 : Fred : [Java, C]?
