What's wrong with my code? (Java)

[GDoughtUpInIt]

Eventually, I'm supposed to display all 7 days of the week with what this guy is going to be doing. So far I only got 1 day done, but I'm still trying to display all the days on the screen, just to get myself started. But I can't get it to display:

MONDAY: (all the stuff i put there so far too)
TUESDAY
WEDNESDAY
THURSDAY
FRIDAY
SATURDAY
SUNDAY

in a loop. Can somebody tell me what is wrong with my code below. I am a beginner in this, but I'm really trying to learn so any help will be appreciated. Thanks

class joesWeek{
public static void main (String[] args){
int x = 0;
int money = 200;
int shoeCost = 30;
double shoeTax = 1.15;

System.out.println("Java Joe has $200.");
while (x<7) {
x=x+1;
if (x==1) {
System.out.println("MONDAY: Joe pays $" + (shoeCost*shoeTax) + " for shoes. He now has $" + (money-(shoeCost*shoeTax)) + " left.");
if (x==2) {
System.out.println("TUESDAY:");
if (x==3) {
System.out.println("WEDNESDAY:");
if (x==4) {
System.out.println("THURSDAY:");
if (x==5) {
System.out.println("FRIDAY:");
if (x==6) {
System.out.println("SATURDAY:");
if (x==7) {
System.out.println("SUNDAY:");
}else{
System.out.println(x);
}
}
}
}
}
}
}
}
}
}

you have all youre ifs inside each other thats why only the first one shows up... it should look like this:

code:

class joesWeek{ public static void main (String[] args){ int money = 200; int shoeCost = 30; double shoeTax = 1.15; System.out.println("Java Joe has $200."); for (int i = 1; i <= 7; i++) { if (i == 1) { println ("whatever"); } else if (i == 2) { println ("blah") } else if (i == 3) { println ("more stuff") { } } }

btw, you might want to look up the "switch" syntax... if you know turing, its like "case"

if (x==2) {
...
}
}

you have all of the branches of your if nested inside x==1. Try:

code:

if (x==1){      ... } else if (x==2){      ... } else if (x==3){      ... } ...

Now tested and shown to work.

code:

import java.lang.*; import java.io.*; public class MyProgram {    public static class Day {       public static class Event {          private String name;          private String description;          private boolean done;          public Event(String n, String desc) {             name = n;             description = desc;             done = false;          }          public String getName() { return name; }          public String getDescription() { return description; }       }       private String name;       private Event[] events;       private int eventCount;       public Day(String n, int numEvents) {          name = n;          events = new Event[numEvents];          eventCount = 0;       }       public String getName() { return name; }       public Event[] getEvents() { return events; }       public int getEventCount() { return eventCount; }       public boolean eventCountFull() { return eventCount >= events.length; }       private void incrementEventCount() { eventCount++; }       public Event getEventByName(String n) {          for (int i = 0; i < events.length; i++) {             if (events[i].getName() == n)                return events[i];          }          return null;       }       public void addEvent(String n, String desc) {          if (!eventCountFull()) {             events[eventCount] = new Event(n, desc);             incrementEventCount();          }       }    }    public static class Week {       private Day[] days;       public Week(int numEventsPerDay) {          days = new Day[7];          String[] dayNames = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };          for (int i = 0; i < 7; i++) {             days[i] = new Day(dayNames[i], numEventsPerDay);          }       }       public Day[] getDays() { return days; }       public Day getDay(String n) {          for (int i = 0; i < 7; i++) {             if (days[i].getName() == n)                return days[i];          }          return null;       }    }    public static void main(String[] args) {       Week joesWeek = new Week(8);       double joesMoney = 200.00;       double shoeCost  =  30.00;       double shoeTax   =   1.15;       double totalShoeCost = shoeCost * shoeTax;       double remainingMoney = joesMoney - totalShoeCost;       Day monday = joesWeek.getDay("Monday");       monday.addEvent("Pay For Shoes", "Joe pays $" + totalShoeCost + " and is left with $" + remainingMoney);       Day[] thisWeek = joesWeek.getDays();       for (int i = 0; i < 7; i++) {          Day today = thisWeek[i];          Day.Event[] todaysEvents = today.getEvents();          int numberOfEvents = today.getEventCount();          System.out.println(today.getName());          for (int j = 0; j < numberOfEvents; j++) {             Day.Event thisEvent = todaysEvents[j];             System.out.println("\t" + thisEvent.getName() + ": " + thisEvent.getDescription());          }       }    } }
