sweets Java program

[andnlou2678]

hi

i am still trying to work out how to do this program i have had lots of help on here on this and for that i am so grateful i am finding java somewhat confusing to say the least but i am not going to give up.

scenario (just in case you don't know all ready.

A teacher has bought a packet of 40 sweets which she is going to share out between her class of 14 students.

Write a program to determine and output the number of sweets each child will receive. As a single sweet can not be shared between pupils, the program must calculate the number of sweets per child and the number that the teacher keeps for herself.

my code so far (with help on here and tutorials)


import java.until.*;
//determine the ouput of number of sweets per child
public class Sweets

{

public static void main (String args[])

{

//create Scanner to read in data
Scanner myKeyboard = new Scanner(System.in);


//prompt user for input – use print to leave cursor on line

System.out.print("Number of sweets ");
int sweets = myKeyboard.nextInt();


System.out.print(" pupil ");
int pupil = myKeyboard.nextInt();

System.out.print("Each pupil ");
int sweet/pupil = myKeyboard.nextInt();


System.out.print("Left for teacher ");
int sweet%pupil= myKeyboard.nextInt();


System.out.println("each pupil gets " + eachPupil +" sweets and " + leftForTeacher+ " sweets are left for teacher");

}

}


the 2 errors i am getting still.

H:\FPT>javac Sweets.java
Sweets.java:25: error: ';' expected
int sweet/pupil = myKeyboard.nextInt();
^
Sweets.java:29: error: ';' expected
int sweet%pupil= myKeyboard.nextInt();
^
2 errors

Many thanks..

Hi there.
You cannot declare variable names with % and /

Sweets.java:25: error: ';' expected
int sweet/pupil = myKeyboard.nextInt();
^
Sweets.java:29: error: ';' expected
int sweet%pupil= myKeyboard.nextInt();

But this should be a solution.

System.out.print(pupil/sweets  + " for each pupil ");
System.out.print(pupil%sweets + " Left for teacher ");

Regards Andy.

hi thanks for the speedy reply so do i need to rewrite my code then?

Many thanks Andy

Look at my above code, i was a bit to slow to add it in the EDIT. so you probably haven't seen it.

Regards Andy.

code:

import java.until.*;
//determine the ouput of number of sweets per child
public class Sweets

{

public static void main (String args[])

{

//create Scanner to read in data
Scanner myKeyboard = new Scanner(System.in);


//prompt user for input – use print to leave cursor on line

System.out.print("Number of sweets ");
int sweets = myKeyboard.nextInt();

System.out.print(" pupil ");
int pupil = myKeyboard.nextInt();

int System.out.print(pupil/sweets + " for each pupil ");

int System.out.print(pupil%sweets + " Left for teacher ");



System.out.println("each pupil gets " + eachPupil +" sweets and " + leftForTeacher+ " sweets are left for teacher");

}

}

2 different errors now..

H:\FPT>javac Sweets.java
Sweets.java:19: error: ';' expected
int System.out.print(pupil/sweets + " for each pupil ");
^
Sweets.java:21: error: ';' expected
int System.out.print(pupil%sweets + " Left for teacher ");

many thanks Andy

ps. how to make the code easy to read for you like you did me when you post.

I think you have misunderstood something :) you should rad up on the basics again. but here i think this will work:

import java.until.*;
//determine the ouput of number of sweets per child
public class Sweets

{

public static void main (String args[])

{

//create Scanner to read in data
Scanner myKeyboard = new Scanner(System.in);


//prompt user for input – use print to leave cursor on line

System.out.print("Number of sweets ");
int sweets = myKeyboard.nextInt();

System.out.print(" pupil ");
int pupil = myKeyboard.nextInt();

int eachPupil =  sweets/pupil;

int leftForTeacher = sweets%pupil;

System.out.println("each pupil gets " + eachPupil +" sweets and " + leftForTeacher + " sweets are left for teacher");

}

}

Regards Andy.

many thanks i am sorry for being a pain i am just starting Java and finding it hard to grasp and is really confusing me but yes i will have to go over from the start again i think (i will get there)

many thanks Andy..

It was not meant as such, but the systom.out.print(String); is a void method meaning you it does not return anything than you can put in an int as such :

int someVariableName =system.out.println(String);

If you want to save your result in a int you can do

int someVariableName =  aInt / anOtherInt;

If you then want to print this you can say

System.out.println("Result: " + someVariableName);

H:\FPT>javac Sweets.java
Sweets.java:1: error: package java.until does not exist
import java.until.*;
^
Sweets.java:12: error: cannot find symbol
Scanner myKeyboard = new Scanner(System.in);
^

Sweets.java:12: error: cannot find symbol

3 errors

Try changing you import in the top to "util" instead of "until"

hi thks for your help got working but does this look right to you?
H:\FPT>java Sweets
Number of sweets 40
Number of Students 14
Number of sweets 0 Number of sweets per child14the number that the teacher keeps
for herself

Many thanks Andy..

hi thks for your help got working but does this look right to you?

Nope, the first number should equal 2 (40/14) and the second number should be 12 (40%14). You must've used the wrong formulas ...

kind regards,

Jos
