Q86. Given: 

interface Pet { } 

class Dog implements Pet { } 

public class Beagle extends Dog{ } 

Which three are valid? 

A. Pet a = new Dog(); 

B. Pet b = new Pet(); 

C. Dog f = new Pet(); 

D. Dog d = new Beagle(); 

E. Pet e = new Beagle(); 

F. Beagle c = new Dog(); 

Answer: A,D,E 

Explanation: 

Incorrect: 

Not B, not C: Pet is abstact, cannot be instantiated. 

Not F: incompatible type. Required Beagle, found Dog. 


Q87. Given the following array:

B. Option B 

C. Option C 

D. Option D 

E. Option E

Q88. 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); 

Answer:


Q89. 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. 

Answer: B,C 

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. 


Q90. Given the code fragments: 

Which code fragment, when inserted at line ni, enables the code to print Hank? 

A. checkAge (iList, ( ) -> p. get Age ( ) > 40); 

B. checkAge(iList, Person p -> p.getAge( ) > 40); 

C. checkAge (iList, p -> p.getAge ( ) > 40); 

D. checkAge(iList, (Person p) -> { p.getAge() > 40; });
