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. 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 QUESTION 123Given: What is the result? A.    boxB.    nboC.    boD.    nbE.    An exception is thrown at runtime Answer: E QUESTION 124Given: Which is true? A.    Sum for 0 to 0 = 55B.    Sum for 0 to 10 = 55C.    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: 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: What is the result? A.    28false29trueB.    285 < 429trueC.    truetrueD.    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.    true, falseB.    false, trueC.    true, trueD.    false, false Answer: BExplanation:== strict equality.equals compare state, not identity. QUESTION 127Given: What is the result? A.    0DoneB.    First ExceptionDoneC.    Second ExceptionD.    DoneThird ExceptionE.    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.    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. QUESTION 129Given:  A.    X XXB.    X Y XC.    Y Y XD.    Y YY Answer: D QUESTION 130Given: 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 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?
