i have 2 little programs that im stuck on.

the first, i need to out put all three numbers from highest to lowest but i can only get it to out put the one largest number and not the other two as well.

the other program im stuck on is trying to get "quit" to exit when equal to "y" and loop back if not "y" "Y" "n" "N". it dosen't even have to loop really.

any help would be greatly appreciated


import cs1.Keyboard;
public class order
{
public static void main (String[] args)
{
int number, number2, number3;

System.out.println("Enter number 1");
number = cs1.Keyboard.readInt();

System.out.println("Enter number 2");
number2 = cs1.Keyboard.readInt();

System.out.println("Enter number 3");
number3 = cs1.Keyboard.readInt();

if (number > number2 && number > number3)
{

System.out.println (number);
}

if (number2 > number3 && number2 > number )

{

System.out.println (number2);
}

else


System.out.println (number3);
}
}






import cs1.Keyboard;
public class converter
{

public static void main (String[] args)
{
int option;
double Pound, Currency;
String quit;



do
{
System.out.println("Please enter GBP amount:");
Pound = cs1.Keyboard.readInt();
System.out.println("Please pick one of the four options:");


System.out.println("1 = Euro");
System.out.println("2 = USD ");
System.out.println("3 = AUD ");
System.out.println("0 = Quit");

option = Keyboard.readInt();



if (option == 1)
{

Currency = Pound * 1.48;
System.out.println("Answer =" +Currency);


System.out.println("Do you wish to quit the programme? ");
System.out.println("Y or N ");
quit = cs1.Keyboard.readString();


do
if(quit != "y")
if(quit != "Y")
if(quit != "n")
if(quit != "N")

System.out.println("try again");

while (!(quit == "y"));


System.out.println("You have quit the programme");



}


else if (option == 2)

{

Currency = Pound * 1.97;
System.out.println("Answer =" +Currency);
}
else if (option == 3)

{

Currency = Pound * 2.43;
System.out.println("Answer =" +Currency);
}
}
while (!(option == 0));
System.out.println("You have quit the programme");


}
}

this part of the code is wrong.. the logic of your conditional statements is wrong.


and so is this..
you have to put the process you want repeated inside the do-while loop and there is no need for these lines (if(quit != "y")if(quit != "Y")if(quit != "n")if(quit != "N")).
