The question types in both Java and Python certification exams are similar and can be classified into the following categories:
1. Selecting the output of a given code: These questions will present you with different output options, along with any exceptions or errors, and ask you to identify the correct output for a code snippet.
Java example:
What is the output of the following code snippet?
int x = 5;
int y = 10;
System.out.println(x + y);
a) 10
b) 510
c) 15
d) x10y5
Python example:
What is the output of the following code snippet?
x = [1,2,3]
y = x * [4,5]
print(y)
a) [1,2,3,4,5]
b) [5,4,3,2,1]
c) [2,4,6]
d) Error
2. Selecting the correct method or function name: These questions will ask you to choose the appropriate method or function name to solve a given problem or code snippet.
Java example:
What is the name of the method used to add elements to an ArrayList?
a) add()
b) insert()
c) put()
d) append()
Python example:
What is the correct function to remove an item from a dictionary?
a) pop()
b) delete()
c) remove()
d) discard()
3. Selecting the missing code: These questions will present you with a code snippet with a missing element and ask you to identify the correct missing code.
Java example:
What is the missing code in the following for loop?
for (int i = 0; i <= 5; i++) {
_____________
}
a) System.out.println(i);
b) int i = 0;
c) i++;
d) i = 1;
Python example:
What is the missing code in the following while loop?
while num < 10:
_____________
a) num += 1
b) print(num)
c) num = 0
d) num * 2
4. Theory questions: These questions will present you with statements and ask you to identify whether they are true or false.
Java example:
True or False: Java is a platform-independent programming language.
Python example:
True or False: Python is a dynamically typed language.
5. Selecting the correct or incorrect statements: These questions will present you with multiple statements and ask you to identify the correct or incorrect ones.
Java example:
Which of the following statements about inheritance in Java is incorrect?
a) A subclass can inherit from multiple superclasses.
b) Private methods and instance variables are inherited by subclasses.
c) A subclass can override methods of its superclass.
d) Constructors cannot be inherited.
Python example:
Which of the following statements about strings in Python is correct?
a) Strings are immutable.
b) Strings can be modified using indexing.
c) Strings can be added to integers.
d) Strings can be used as keys in dictionaries.
6. Choosing one or more code snippets to solve a problem: These questions will provide a business scenario or problem and ask you to select the appropriate code snippet(s) to solve it.
Java example:
How would you write a method to calculate the average of two numbers?
a) double average(int x, int y) {
return (x + y) / 2;
}
b) void average(int x, int y) {
System.out.println((x + y) / 2);
}
c) int average(int x, int y) {
return (x + y) / 2;
}
d) float average(int x, int y) {
return (x + y) / 2;
}
Python example:
How would you write a function to check if a number is prime?
a)
def prime(n):
for i in range(2, n):
if n % i == 0:
return False
return True
b)
def prime(n):
if n < 2:
return False
for i in range(2, n):
if n % i == 0:
return False
return True
c)
def prime(n):
for i in range(2, n):
if n % i == 0:
return True
return False
d)
def prime(n):
if n < 2:
return False
for i in range(2, n):
if n % i == 0:
return True
return False
