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?
B. Found 3 at 3
C. Compilation fails
D. An exception is thrown at runtime
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.
Given:
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?
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
class java.lang.String
class java.util.List
Explanation:
class java.lang.StringBuilder
class java.lang.String
class java.util.ArrayList
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?
B. nbo
C. bo
D. nb
E. An exception is thrown at runtime
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?
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
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.

Given the code fragment:
System.out.println(28 + 5 <= 4+ 29);
System.out.println((28 + 5) <= (4 + 29));
What is the result?
true
B. 285 < 429
true
C. true
true
D. compilation fails
Given:
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?
B. false, true
C. true, true
D. false, false
Explanation:
== strict equality.
equals compare state, not identity.
Given:
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?
Done
B. First Exception
Done
C. Second Exception
D. Done
Third Exception
E. Third Exception
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 obj1 = null;
obj2.num = 60;
graceMarks(obj2);
}
}
How many objects are created in the memory runtime?
B. 2
C. 3
D. 4
Explanation:
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.
Given:
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?
B. X Y X
C. Y Y X
D. Y YY
Given:
class Patient {
String name;

this.name = name;
}
}
9. public static void main(String[] args) {

11. Patient p2 = new Patient(“Mike”);
12. ps.add(p2);
13.

15.
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?
B. int f = ps.indexOf (patient("Mike"));
C. patient p = new Patient ("Mike");
int f = pas.indexOf(P);
D. int f = ps.indexOf(p2);
Given:
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?
B. Null Unix Linux Solaris
C. Class java.lang.Exception
D. Class java.lang.NullPointerException
Explanation:
null Unix Linux Solarios
The first element, arr[0], has not been defined.
Given:
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?
B. 2 4 6 8 10 12 14
C. Compilation fails
D. The program prints multiple of 2 infinite times
E. The program prints nothing
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;
}
}
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
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.
https://docs.oraclexom/javase/tutorial/java/Iandl/defaultmethods.html
Consider following method:
default void print() {
}
Which statement is true?
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.
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.
Given:
public class MyFor3 {
public static void main(String[] args) {
int[] xx = null;
for(int ii : xx) {
System.out.println(ii);
}
}
}
What is the result?
B. Compilation fails
C. An exception is thrown at runtime
D. 0
Given:

2. public static void main(String[] args) {
3. float myarray[] = {10.20f, 20.30f, 30.40f, 50.60f};
4. int index = 0;
5. boolean isFound = false;
6. float key = 30.40f;
7. //insert code here
8. System.out.println(isFound);
9. }
10. }
Which code fragment, when inserted at line 7, enables the code print true?
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 A
B. Option B
C. Option C
D. Option D
