Cuestionario 7. 1Z0-808

Given the following array:

int[] intArr = {8, 16, 32, 64, 128};

Which two code fragments, independently, print each element in this array?

Given the content of three files:

A.java
public class A {
 
    public void a() {
    }
    int a;
}

===================================

B.java
public class B {
 
    private int doStuff(){
        private int x = 100;
        return x++;
    }
}

===================================

C.java
import java.io.*;
package p1;
 
class C {
 
    public void main(String fileName) throws IOException {
    }
}

Which statement is true?

Given the code fragment:

int[] array = {1, 2, 3, 4, 5};

And given the requirements:

Process all the elements of the array in the order of entry.
Process all the elements of the array in the reverse order of entry.
Process alternating elements of the array in the order of entry.

Which two statements are true?

Given:

public class TestScope {
 
    public static void main(String[] args) {
        int var1 = 200;
        System.out.print(doCalc(var1));
        System.out.print(" " + var1);
    }
 
    static int doCalc(int var1) {
        var1 = var1 * 2;
        return var1;
    }
}

What is the result?

Given the following class declarations:

public abstract class Animal
public interface Hunter
public class Cat extends Animal implements Hunter
public class Tiger extends Cat

Which answer fails to compile?

Which statement is true about Java byte code?

Given:

public class MarkList {
 
    int num;
 
    public static void graceMarks(MarkList obj4) {
        obj4.num += 10;
    }
 
    public static void main(String[] args) {
        MarkList obj1 = new MarkList();
        MarkList obj2 = obj1;
        MarkList obj3 = null;
        obj2.num = 60;
        graceMarks(obj2);
    }
}

How many objects are created in the memory runtime?
