Color Program

The user should input this following letter:

if Y the result should be YELLOW,  if R the result should be RED,  if W the result should be WHITE, if V the result should be VIOLET, if P the result should be PINK, if the user will input none of those letter ten the output should be "NO COLOR AVAILABLE!"

Code:

Here's the code:

package color;
import java.util.Scanner;

public class Color {
static Scanner console=new Scanner(System.in);
    public static void main(String[] args) {
       
         String input; char letter;
        System.out.println("Enter a letter:");
        input=console.next();
        letter=input.charAt(0);

ATM System

Problem: Create a program for a BANK called ATM SYSTEM

Transactions are:

- Balance Inquiry
- Withdraw
- Change Pin

NOTE: 

1.)  There will be 5 account holders
        - Name
        - Pin

2.) Ask for a transaction

3.) Perform the transaction

4.) Ask another transaction (Y/N) if  "Y" loop again

Code: 

package atm;
import java.util.Scanner;
public class Atm {
static Scanner candy = new Scanner (System.in);
public static void main(String[] args){

What is Cloud Computing?

Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user's data, software and computation.

There are many types of public cloud computing:

Infrastructure as a service (IaaS),

Platform as a service (PaaS),

Software as a service (SaaS)

Storage as a service (STaaS)

Security as a service (SECaaS)

Data as a service (DaaS)

Business process as a service (BPaaS)

Test environment as a service (TEaaS)

Desktop as a service (DaaS)

API as a service (APIaaS)

Adding even numbers (1-20)

Code:

package gene;
import java.util.Scanner;

public class Gene {
static Scanner console=new Scanner(System.in);
    public static void main(String[] args) {
    
        int sum=0;
        for(int i=0;i<=20;i++){
            if((i%2)==0){
            sum=i+sum;
        }
    
    
    }
System.out.println("sum = "+sum);
    }

}

Adding even numbers from 1-20 applying METHODS

This is our class work, the problem is to add even numbers from 1-20 using methods.

WITH RETURN TYPE WITH PARAMETER

package gene1;
import java.util.Scanner;
public class Gene1 {
static Scanner console=new Scanner(System.in);
    public static void main(String[] args) {
     
        int sum=0;
        System.out.println( "sum = " +Odd(sum) );
       }
 
    static int Odd(int x){
         for(int i=0;i<=20;i+=2){
           x=x+i;
     
    }
         return x;
}
 
}

WITH PARAMETER WITHOUT RETURN TYPE

package gene2;
import java.util.Scanner;
public class Gene2 {
static Scanner console=new Scanner (System.in);
    public static void main(String[] args) {
     
        int sum=0;
        Even(sum);
        }
 
    static void Even(int x){
         for(int i=0;i<=20;i+=2){
           x=x+i;
       

    }
         System.out.println("sum="+x);
    }
   
}

WITH RETURN TYPE WITHOUT PARAMETER

package gene3;
import java.util.Scanner;
public class Gene3 {
    static Scanner console=new Scanner(System.in);
    public static void main(String[] args) {
        
        Even();
        
    }
    private static int Even(){
        int x = 0;
        for(int i=0;i<=20;i+=2){
           x=x+i;
             System.out.println("sum = "+x);
         
    }
        return x;
}

}

Diamond (Nested for-loop)

Code:

package diamond;
public class Diamond {

    public static void main(String[] args) {
    for (int i = 1; i < 10; i += 2) {
    for (int j = 0; j < 9 - i / 2; j++)
 

    for (int j = 0; j < i; j++)
        System.out.print("*");

      System.out.print("\n");
    }

    for (int i = 7; i > 0; i -= 2) {
      for (int j = 0; j < 9 - i / 2; j++)
        System.out.print(" ");

      for (int j = 0; j < i; j++)
        System.out.print("*");

      System.out.print("\n");
    }
  }
}

THE OUTPUT:

Circle: Diameter,Circumference,Area

Problem: Write a Java Program that calculates and prints the diameter, circumference, or the area of a circle given the radius. The application should input a character corresponding the one of the three actions:
           
             D-  Diameter
             C-  Circumference
             A-  Area


CODE:

package circle;
import java.util.Scanner;

public class Circle {
    static Scanner gene=new Scanner(System.in);

    public static void main(String[] args) {
        char choice;
        String input;
        int rad;
        double ans;
   
        System.out.println("**PLEASE CHOOSE**");
        System.out.println("[D]iameter");
        System.out.println("[C]ircumference");
        System.out.println("[A]rea");
        System.out.println("Enter your Choice:");
        input=gene.next();
        choice=input.charAt(0);
        System.out.println("Enter the radius of the circle:");
        rad=gene.nextInt();
   
        switch(choice){
            case 'D': case 'd': System.out.println("Diameter");
             ans=2*rad;
            System.out.println("Answer:"+ans);
             break;

       
            case 'C': case 'c': System.out.println("Circumference");
            ans=2*3.14159265*rad;
            System.out.println("Answer:"+ans);
            break;

       
             case 'A': case 'a': System.out.println("Area");
             ans=3.14159265*rad*rad;
            System.out.println("Answer:"+ans);
            break;

default: System.out.println("INVALID INPUT");break;
 
             }

      }
}

   
   
 

Food Menu Program

Problem: Create a Java Program that uses Control Statements (must use switch-case statement and ladderized if-else ) that presents a menu of a fast food chain at least 5.

Consider the following:
a. The user of your program is the costumer.
b. The Costumer selects one menu.
c. Consider Discounts
         c.1  If the costumer is a Senior Citizen (give 20% Discount from the total amount due)
         c.2 If the costumer is a Student (give 5.5% Discount)
         c.3 If None of the (2) options No Discount will be given
