Q81. View the exhibit:

public class Student {

public String name = "";

public int age = 0;

public String major = "Undeclared";

public boolean fulltime = true;

public void display() {

System.out.println("Name: " + name + " Major: " + major); }

public boolean isFullTime() {

return fulltime;

Which line of code initializes a student instance?

A. Student student1;

B. Student student1 = Student.new();

C. Student student1 = new Student();

D. Student student1 = Student();

Q82. Given:

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);

Q83. Given:

What is the output?

A. [21, 13, 11]

B. 

C. []

D. Compilation fails due to error at line 7

E. Compilation tails due to error at line 10

Explanation:

Option D is the correct answer.

Code fails to compile as we can't use primitive for collections type, so in this code trying to

use int at line 7, causes a compile error. We should have use wrapper. Integer there. So

option D is correct.

Q84. 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

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.

Q85. int i, j=0;

i = (3* 2 +4 +5 ) ;

j = (3 * ((2+4) + 5));

System.out.println("i:"+ i + "\nj":+j);

What is the result?

A. Option A

B. Option B

C. Option C

D. Option D

### Renovate 1z0-808 book:

Q86. You are asked to develop a program for a shopping application, and you are given the following information:

. The application must contain the classes Toy, EduToy, and consToy. The Toy class is the superclass of the other two classes.

. The int caicuiatePrice (Toy t) method calculates the price of a toy.

. The void printToy (Toy t) method prints the details of a toy.

Which definition of the Toy class adds a valid layer of abstraction to the class hierarchy?

A. Option A

B. Option B

C. Option C

D. Option D

Q87. Given the code fragment:

What is the result?

B. Compilation fails only at line n1.

C. Compilation fails only at line n2.

D. Compilation fails only at line n3.

E. Compilation fails at both line n2 and line n3.

Q88. Given the for loop construct:

for ( expr1 ; expr2 ; expr3 ) {

statement;

Which two statements are true?

A. This is not the only valid for loop construct; there exits another form of for loop constructor.

B. The expression expr1 is optional. it initializes the loop and is evaluated once, as the loop begin.

C. When expr2 evaluates to false, the loop terminates. It is evaluated only after each iteration through the loop.

D. The expression expr3 must be present. It is evaluated after each iteration through the loop.

Explanation:

The for statement have this forms:

for (init-stmt; condition; next-stmt) {

body

There are three clauses in the for statement.

The init-stmt statement is done before the loop is started, usually to initialize an iteration

variable.

The condition expression is tested before each time the loop is done. The loop isn't

executed if the boolean expression is false (the same as the while loop).

The next-stmt statement is done after the body is executed. It typically increments an

iteration variable.

Q89. Given the code fragment

Which code fragments, inserted independently, enable the code compile?

A. t.fvar = 200;

B. cvar = 400;

C. fvar = 200; cvar = 400;

D. this.fvar = 200; this.cvar = 400;

E. t.fvar = 200; Test2.cvar = 400;

F. this.fvar = 200; Test2.cvar = 400;

Q90. 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?

A. true, false

B. false, true

C. true, true

D. false, false
