2017 March Oracle Official New Released 1Z0-808 Q&amp;As in Lead2pass.com!  100% Free Download! 100% Pass Guaranteed!  Since I recently passed the the Oracle 1Z0-808 exam, it's time for me to share the Lead2pass exam dumps I used when preparing for this exam. Following questions and answers are all new published by Oracle Official Exam Center: http://www.lead2pass.com/1z0-808.html  QUESTION 121Given: public class TestLoop {public static void main(String[] args) {int array[] = {0, 1, 2, 3, 4};int key = 3;for (int pos = 0; pos &lt; array.length; ++pos) {if (array[pos] == key) {break;}}System.out.print("Found " + key + "at " + pos);}} What is the result? A.&nbsp;&nbsp;&nbsp; Found 3 at 2B.&nbsp;&nbsp;&nbsp; Found 3 at 3C.&nbsp;&nbsp;&nbsp; Compilation failsD.&nbsp;&nbsp;&nbsp; An exception is thrown at runtimeAnswer: CExplanation: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. QUESTION 122Given: import java.util.*;public class Ref {public static void main(String[] args) {StringBuilder s1 = new StringBuilder("Hello Java!");String s2 = s1.toString();List&lt;String&gt; lst = new ArrayList&lt;String&gt;();lst.add(s2);System.out.println(s1.getClass());System.out.println(s2.getClass());System.out.println(lst.getClass());}} What is the result? A.&nbsp;&nbsp;&nbsp; class java.lang.Stringclass java.lang.Stringclass java.util.ArrayListB.&nbsp;&nbsp;&nbsp; class java.lang.Objectclass java.lang. Objectclass java.util.CollectionC.&nbsp;&nbsp;&nbsp; class java.lang.StringBuilderclass java.lang.Stringclass java.util.ArrayListD.&nbsp;&nbsp;&nbsp; class java.lang.StringBuilderclass java.lang.Stringclass java.util.List Answer: CExplanation:class java.lang.StringBuilderclass java.lang.Stringclass java.util.ArrayList QUESTION 123Given: &nbsp; What is the result? A.&nbsp;&nbsp;&nbsp; boxB.&nbsp;&nbsp;&nbsp; nboC.&nbsp;&nbsp;&nbsp; boD.&nbsp;&nbsp;&nbsp; nbE.&nbsp;&nbsp;&nbsp; An exception is thrown at runtime Answer: E QUESTION 124Given: &nbsp; Which is true? A.&nbsp;&nbsp;&nbsp; Sum for 0 to 0 = 55B.&nbsp;&nbsp;&nbsp; Sum for 0 to 10 = 55C.&nbsp;&nbsp;&nbsp; Compilation fails due to error on line 6.D.&nbsp;&nbsp;&nbsp; Compilation fails due to error on line 7.E.&nbsp;&nbsp;&nbsp; An Exception is thrown at the runtime. Answer: DExplanation: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. Reference: httpsy/docs.oracle.com/javase/tutorial/java/nutsandbolts/variables.html QUESTION 125Given the code fragment: &nbsp; What is the result? A.&nbsp;&nbsp;&nbsp; 28false29trueB.&nbsp;&nbsp;&nbsp; 285 &lt; 429trueC.&nbsp;&nbsp;&nbsp; truetrueD.&nbsp;&nbsp;&nbsp; compilation fails Answer: C QUESTION 126Given: public class Equal {public static void main(String[] args) {String str1 = "Java";String[] str2 = {"J","a","v","a"};String str3 = "";for (String str : str2) {str3 = str3+str;}boolean b1 = (str1 == str3);boolean b2 = (str1.equals(str3));System.out.print(b1+", "+b2);} What is the result? A.&nbsp;&nbsp;&nbsp; true, falseB.&nbsp;&nbsp;&nbsp; false, trueC.&nbsp;&nbsp;&nbsp; true, trueD.&nbsp;&nbsp;&nbsp; false, false Answer: BExplanation:== strict equality.equals compare state, not identity. QUESTION 127Given: &nbsp; What is the result? A.&nbsp;&nbsp;&nbsp; 0DoneB.&nbsp;&nbsp;&nbsp; First ExceptionDoneC.&nbsp;&nbsp;&nbsp; Second ExceptionD.&nbsp;&nbsp;&nbsp; DoneThird ExceptionE.&nbsp;&nbsp;&nbsp; Third Exception Answer: B QUESTION 128Given: 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 obj1 = null;obj2.num = 60;graceMarks(obj2);}} How many objects are created in the memory runtime?  A.&nbsp;&nbsp;&nbsp; 1B.&nbsp;&nbsp;&nbsp; 2C.&nbsp;&nbsp;&nbsp; 3D.&nbsp;&nbsp;&nbsp; 4 Answer: BExplanation:obj1 and obj3.when you do e2 = e1 you're copying object references - you're not making a copy of the object - and so the variables e1 and e2 will both point to the same object. QUESTION 129Given: &nbsp; A.&nbsp;&nbsp;&nbsp; X XXB.&nbsp;&nbsp;&nbsp; X Y XC.&nbsp;&nbsp;&nbsp; Y Y XD.&nbsp;&nbsp;&nbsp; Y YY Answer: D QUESTION 130Given: &nbsp; Which code fragment, when inserted at line 14, enables the code to print Mike Found? A.&nbsp;&nbsp;&nbsp; int f = ps.indexOf {new patient ("Mike")};B.&nbsp;&nbsp;&nbsp; int f = ps.indexOf (patient("Mike"));C.&nbsp;&nbsp;&nbsp; patient p = new Patient ("Mike");int f = pas.indexOf(P)D.&nbsp;&nbsp;&nbsp; int f = ps.indexOf(p2); Answer: C QUESTION 131Given: public class Test {public static void main(String[] args) {try {String[] arr =new String[4];arr[1] = "Unix";arr[2] = "Linux";arr[3] = "Solarios";for (String var : arr) {System.out.print(var + " ");}} catch(Exception e) {System.out.print (e.getClass());}}} What is the result? A.&nbsp;&nbsp;&nbsp; Unix Linux SolarisB.&nbsp;&nbsp;&nbsp; Null Unix Linux SolarisC.&nbsp;&nbsp;&nbsp; Class java.lang.ExceptionD.&nbsp;&nbsp;&nbsp; Class java.lang.NullPointerException Answer: BExplanation:null Unix Linux SolariosThe first element, arr[0], has not been defined. QUESTION 132Given: &nbsp; What is the result? A.&nbsp;&nbsp;&nbsp; 2 4 6 8 10 12B.&nbsp;&nbsp;&nbsp; 2 4 6 8 10 12 14C.&nbsp;&nbsp;&nbsp; Compilation failsD.&nbsp;&nbsp;&nbsp; The program prints multiple of 2 infinite timesE.&nbsp;&nbsp;&nbsp; The program prints nothing Answer: B QUESTION 133Which of the following can fill in the blank in this code to make it compile? &nbsp; A.&nbsp;&nbsp;&nbsp; abstractB.&nbsp;&nbsp;&nbsp; publicC.&nbsp;&nbsp;&nbsp; defaultD.&nbsp;&nbsp;&nbsp; It will not compile with any as interfaces cannot have non abstract methods.E.&nbsp;&nbsp;&nbsp; It will compile without filling the blank. Answer: CExplanation: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.https;//docs.oraclexom/javase/tutorial/java/Iandl/defaultmethods.html QUESTION 134Consider following method &nbsp; Which statement is true? A.&nbsp;&nbsp;&nbsp; This method is invalid.B.&nbsp;&nbsp;&nbsp; This method can be used only in an interface.C.&nbsp;&nbsp;&nbsp; This method can return anything.D.&nbsp;&nbsp;&nbsp; This method can be used only in an interface or an abstract class.E.&nbsp;&nbsp;&nbsp; None of above. Answer: BExplanation: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. QUESTION 135Given: &nbsp; What is the result? A.&nbsp;&nbsp;&nbsp; NullB.&nbsp;&nbsp;&nbsp; Compilation failsC.&nbsp;&nbsp;&nbsp; An exception is thrown at runtimeD.&nbsp;&nbsp;&nbsp; 0 Answer: C QUESTION 136Given: &nbsp; Which code fragment, when inserted at line 7, enables the code print true? &nbsp; A.&nbsp;&nbsp;&nbsp; Option AB.&nbsp;&nbsp;&nbsp; Option BC.&nbsp;&nbsp;&nbsp; Option CD.&nbsp;&nbsp;&nbsp; Option D Answer: A QUESTION 137Given: class Base {public static void main(String[] args) {System.out.println("Base " + args[2]);}}public class Sub extends Base{public static void main(String[] args) {System.out.println("Overriden " + args[1]);}}And the commands:javac Sub.javajava Sub 10 20 30 What is the result? A.&nbsp;&nbsp;&nbsp; Base 30B.&nbsp;&nbsp;&nbsp; Overridden 20C.&nbsp;&nbsp;&nbsp; Overridden 20Base 30D.&nbsp;&nbsp;&nbsp; Base 30Overridden 20 Answer: B QUESTION 138Given: &nbsp; What will be the output? &nbsp; A.&nbsp;&nbsp;&nbsp; Option AB.&nbsp;&nbsp;&nbsp; Option BC.&nbsp;&nbsp;&nbsp; Option CD.&nbsp;&nbsp;&nbsp; Option D Answer: D QUESTION 139Given the code fragments: &nbsp; What is the result? A.&nbsp;&nbsp;&nbsp; SuperSubSubB.&nbsp;&nbsp;&nbsp; ContractContractSuperC.&nbsp;&nbsp;&nbsp; Compilation fails at line n1D.&nbsp;&nbsp;&nbsp; Compilation fails at line n2 Answer: D QUESTION 140Given: &nbsp; What is the result?
