Question

OBJECTIVE: Demonstrate the ability to write Java code for the four basic programming structures and be introduced to Object Oriented Programming, OOP, and Classes. Demonstrate correct usage of syntax, format, comments and naming conventions. ASSIGNMENT: Complete the classic HELLO WORLD program. Show simple example code for each of the four basic programming structures. o Sequence If-Then If-Then-Else ° Looping Use the Scanner class and instantiate an object to accept user input from the keyboard

Explanation / Answer

(Ans- )

Following are the simple java code for the basic programming structures:-

1. Sequence:

public class sequence

{

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.print("Following is the sequence: ");

int N = in.nextInt();

int tall = 1;

for(int i = 0; i <=45; i++){

System.out.println(" " + i);

}

}

}

2. IF Statement :

OUTPUT:

3.IF-THEN-ELSE-STATEMENT :-

OUTPUT:

4. looping in JAVA :

WHILE LOOP

class while_Loop

{

    public static void main(String args[])

    {

        int a = 1;

        while (a <= 4)

        {

            System.out.println("Value of a:" + a);

a++;

        }

    }

}

OUTPUT:

FOR LOOP

class for_Loop

{

    public static void main(String args[])

    {

for (int a = 2; a <= 4; a++)

            System.out.println("Value of a:" + a);

    }

}

Output:

DO-WHILE LOOP :

class Do_While_Loop

{

    public static void main(String args[])

    {

        int a = 21;

        do

        {

System.out.println("Value of a:" + a);

a++;

        }

        while (a < 20);

    }

}

Output:
