Passed 1Z0-808 exam few days ago for the third try!!! Scored 90%! (The first time: 55%, the second time: 64%, the third time: the best score!!!)

80 questions in total.

1. Only few questions on Java: advantages of the Java exception mechanism, the object-oriented features of the Java language, Java byte code, the name of the Java concept that uses access modifiers to protect variables and hide them within a class…etc.

2. Most of the questions are on Giving Code … tell the result (output), which statement is true, choose the best option … and so on.

I mainly used the PassLeader 1Z0-808 dumps: http://www.passleader.com/1z0-808.html (120q VCE and PDF dumps)

All questions were from it, which is the most valid 1Z0-808 dumps, RECOMMEND!!!

NEW QUESTION 121
Given:
public class TestLoop {
public static void main(String[] args) {
int array[] = {0, 1, 2, 3, 4};
int key = 3;
for (int pos = 0; pos < array.length; ++pos) {
if (array[pos] == key) {
break;
}
}
System.out.print("Found " + key + "at " + pos);
}
}
What is the result?

A. Found 3 at 2
B. Found 3 at 3
C. Compilation fails
D. An exception is thrown at runtime

Answer: C
Explanation:
The following line does not compile:
System.out.print("Found " + key + "at " + pos);
The variable pos is undefined at this line, as its scope is only valid in the for loop. Any variables created inside of a loop are LOCAL TO THE LOOP.

NEW QUESTION 122

import java.util.*;
public class Ref {
public static void main(String[] args) {
StringBuilder s1 = new StringBuilder("Hello Java!");
String s2 = s1.toString();
List lst = new ArrayList();
lst.add(s2);
System.out.println(s1.getClass());
System.out.println(s2.getClass());
System.out.println(lst.getClass());
}
}
What is the result?

A. class java.lang.String
class java.lang.String
class java.util.ArrayList
B. class java.lang.Object
class java.lang. Object
class java.util.Collection
C. class java.lang.StringBuilder
class java.lang.String
class java.util.ArrayList
D. class java.lang.StringBuilder

NEW QUESTION 123
Given:
public class Case {
public static void main(String[] args) {
String product = “Pen”;
product.toLowerCase();
product.contact(“ Box”.toLowerCase());
System.out.print(product.substring(4,6));
}
}
What is the result?

A. box
B. nbo

NEW QUESTION 124
Given:
1. public class Whizlabs {
2. public static void main(String[] args) {
3. int sum = 0;
4.
5. for(int x = 0; x <= 10; x++)
6. sum += x;
7. System.out.print(“Sum for 0 to ” + x);
8. System.out.println(“ = ” + sum);
9. }
10. }
Which is true?

A. Sum for 0 to 0 = 55
B. Sum for 0 to 10 = 55
C. Compilation fails due to error on line 6
D. Compilation fails due to error on line 7
E. An Exception is thrown at the runtime

Answer: D
Explanation:
Loop variables scope limited to that enclosing loop. So in this case, the scope of the loop variable x declared at line 5, limited to that for loop. Trying to access that variable at line 7, which is out of scope of the variable x, causes a compile time error. So compilation fails due to error at line 7. Hence option D is correct. Options A and B are incorrect, since code fails to compile.

NEW QUESTION 125
Given the code fragment:
System.out.println(28 + 5 <= 4+ 29);

A. 28false29
true
B. 285 = 0) {
17. System.out.print(“Mike Found”);
18. }
19. }
20. }
Which code fragment, when inserted at line 14, enables the code to print Mike Found?

A. int f = ps.indexOf {new patient (“Mike”)};
B. int f = ps.indexOf (patient(“Mike”));
C. patient p = new Patient (“Mike”);
int f = pas.indexOf(P);
D. int f = ps.indexOf(p2);

Answer: C

NEW QUESTION 133
Which of the following can fill in the blank in this code to make it compile?
interface CanFly {
String type = “A”;
Void fly();
____ String getType() {
Return type;
}
}

A. abstract
B. public
C. default
D. It will not compile with any as interfaces cannot have non abstract methods
E. It will compile without filling the blank

Answer: C
Explanation:
From Java SE 8, we can use static and/or default methods in interfaces, but they should be non abstract methods. SO in this case using default in blank is completely legal. Hence option C is correct. Option A is incorrect as given method is not abstract, so can’t use abstract there. Options B and E are incorrect as we can’t have non abstract method interface if they are not default or static.

NEW QUESTION 134
Consider following method:
default void print() {
}
Which statement is true?

A. This method is invalid.
B. This method can be used only in an interface.
C. This method can return anything.
D. This method can be used only in an interface or an abstract class.
E. None of above.

Answer: B
Explanation:
Given method is declared as default method so we can use it only inside an interface. Hence option B is correct and option D is incorrect. Option A is incorrect as it is valid method. Option C is incorrect as return type is void, which means we can’t return anything.

NEW QUESTION 135
Given:
public class MyFor3 {
public static void main(String[] args) {

}
What is the result?

A. Null
B. Compilation fails
C. An exception is thrown at runtime
D. 0

Answer: C

4. int index = 0;
5. boolean isFound = false;
6. float key = 30.40f;
7. //insert code here
8. System.out.println(isFound);
