Java Fundamentals

Reorder the following Java program structure

• package helloworld;

• public class HelloWorld{

• public static void main (String [ ] args) {

• System.out.println("Hello World from Java");

• }

  }

Organize these options into the right categories

Groups:

(a) Arithmetic Operators

,

(b) Assignment Operators

,

(c) Comparison Operators

,

(d) Logical Operators

• *

• +=

• >=

• /=

• ==

• <

• !

• !=

• >

• -

• ++

• &&

• +

• -=

• <=

• ||

• %=

• %

• *=

• /

Drag the following missing parts of for loop to its correct place in order to display numbers from 1 to 10. for ( ​ (a)   x<=10;​ (b)   ){

System.​ (c)   println(​ (d)   )​ (e)  

• out.
• x
• ;
• int x=1;
• x++;

Match the following

• 'a'

• char
• 5.2

• boolean
• 5

• String
• "abc"

• int
• true

• float

Print "Hello World" if x is greater than y.

​ (a)   x​ (b)   50 ​ (c)   y = 10;

​ (d)   (x​ (e)   y) {

System.out.println("Hello World");

}

• ,
• int
• =
• if
• >

Insert the missing parts to complete the following switch statement. (a)   day = 2;

switch (​ (b)   ) {

​ (c)   1: System.out.println("Saturday");

​ (d)  

case ​ (e)   : System.out.println("Sunday");

break;

}

• case
• 2
• break;
• day
• int

What is the main aim of OOP?

• To structure and organize complex code using objects and classes.
• To increase code duplication and redundancy.
• To eliminate the need for classes and objects.
• To make code more confusing and difficult to understand.

What are the advantages of using OOP?

• It helps in structuring and organizing complex code using objects and classes.

• It increases code duplication and redundancy.

• It eliminates the need for classes and objects.

• It makes code more confusing and difficult to understand.

What is encapsulation in OOP?

• It is a process of hiding the internal details of an object and providing access only through public methods.

• It is a process of exposing the internal details of an object and providing direct access to its properties.

• It is a process of creating multiple instances of an object.

• It is a process of defining the structure and behavior of an object.
