New 1Z0-808 dumps PDF: P.S. New 1Z0-809 dumps PDF: NEW 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 < array.length; ++pos) {if (array[pos] == key) {break;}}System.out.print("Found " + key + "at " + pos);}}What is the result? A.    Found 3 at 2B.    Found 3 at 3C.    Compilation failsD.    An exception is thrown at runtime Answer: 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. NEW 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<String> lst = new ArrayList<String>();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.Stringclass java.lang.Stringclass java.util.ArrayListB.    class java.lang.Objectclass java.lang. Objectclass java.util.CollectionC.    class java.lang.StringBuilderclass java.lang.Stringclass java.util.ArrayListD.    class java.lang.StringBuilderclass java.lang.Stringclass java.util.List Answer: CExplanation:class java.lang.StringBuilderclass java.lang.Stringclass java.util.ArrayList NEW QUESTION 123Given:public class Case {public static void main(String[] args) {String product = “Pen”;product.toLowerCase();“ Box”.toLowerCase());System.out.print(product.substring(4,6));}}What is the result? A.    boxB.    nboC.    boD.    nbE.    An exception is thrown at runtime Answer: E NEW QUESTION 124Given: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 = 55B.    Sum for 0 to 10 = 55C.    Compilation fails due to error on line 6D.    Compilation fails due to error on line 7E.    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: NEW QUESTION 125Given the code fragment:System.out.println(28 + 5 <= 4+ 29);System.out.println((28 + 5) <= (4 + 29));What is the result? A.    28false29trueB.    285 < 429trueC.    truetrueD.    compilation fails Answer: C NEW 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.    true, falseB.    false, trueC.    true, trueD.    false, false Answer: BExplanation:== strict equality.equals compare state, not identity. NEW QUESTION 127Given:public class Test {static void dispResult(int[] num) {try {System.out.println(num[1] / (num[1] – num[2]));} catch(ArithmeticException e) {System.err.println(“first exception”);}System.out.println(“Done”);}public static void main(String[] args) {try {int [] arr = (100, 100);dispResult(arr);} catch(IllegalArgumentException e) {System.err.println(“second exception”);} catch(Exception e) {System.err.println(“third exception”);}}}What is the result? A.    0DoneB.    First ExceptionDoneC.    Second ExceptionD.    DoneThird ExceptionE.    Third Exception Answer: B NEW 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.    1B.    2C.    3D.    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. NEW QUESTION 129Given:public class X implements Z {public String toString() {return “X”;}Public static void main(String[] args) {Y myY = new Y();X myX = myY;Z myZ = myX;System.out.print(myX);System.out.print((Y)myX);System.out.print(myZ);}}class Y extends X {public String toString() {return “Y”;}}What is the result? A.    X XXB.    X Y XC.    Y Y XD.    Y YY Answer: D NEW QUESTION 130Given:class Patient {String name;public Patient(String name) { = name;}} And the code fragment: 8. public class Test {9.    public static void main(String[] args) {10.        List ps = new ArrayList();11.        Patient p2 = new Patient(“Mike”);12.        ps.add(p2);13.14.        //insert code here15.16.        if(f >= 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 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.    Unix Linux SolarisB.    Null Unix Linux SolarisC.    Class java.lang.ExceptionD.    Class java.lang.NullPointerException Answer: BExplanation:null Unix Linux SolariosThe first element, arr[0], has not been defined. NEW QUESTION 132Given:public class Series {private boolean flag;public void displaySeries() {int num = 2;while(flag) {if(num%7 == 0)flag = false;System.out.print(num);Num += 2;}}public static void main(String[] args) {new Series().displaySeries();}}What is the result? A.    2 4 6 8 10 12B.    2 4 6 8 10 12 14C.    Compilation failsD.    The program prints multiple of 2 infinite timesE.    The program prints nothing Answer: B NEW QUESTION 133Which 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.    abstractB.    publicC.    defaultD.    It will not compile with any as interfaces cannot have non abstract methodsE.    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 NEW QUESTION 134Consider 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: 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. NEW QUESTION 135Given:public class MyFor3 {public static void main(String[] args) {int[] xx = null;for(int ii : xx) {System.out.println(ii);}}}What is the result?

Option A.while(key == myarray[index++1]) {isFound == ture;}Option B.while(index <= 4) {if(key == myarray[index]) {index++;isFound = true;break;}}Option C.while(index++ < 5) {if(key == myarray[index]) {isFound = true;}}Option D.while(index < 5) {if(key == myarray[index]) {isFound = true;break;}index++;}A.    Option AB.    Option BC.    Option CD.    Option D Answer: A NEW 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 30What is the result?
