Working with $

I am writing a program and trying to multiply with $ if thats even possible.

I am coding a program where the user enters a number, and the output is $$$ of the number entered. So if one is entered, then one $ is output, and so on.


Thanks in advance!

Why not just put "$" + input

System.out.println("$ " + input);

If 100is entered then the output would be $ 100

I don't need it to be $100....I would need 100 dollar signs..... as in the output would be. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

lol

Use a for loop with a print() statement

Sorry....i'm pretty new to programming......example?

Can you write a for loop? write one that loops 100 times.
Inside the loop use the print() statement to print a $

Here's a tutorial on for loops:
The for Statement (The Java™ Tutorials > Learning the Java Language > Language Basics)

I don't think that'd work.....maybe i'm not explaining it correctly..... If the user enters 7 as the input, the output would be $$$$$$$. If the user enters 3 as the input, the output would be $$$. and so on....

Did you try it?
Write the code, execute it and post the output to show what it does.

Lab7_Ex1.java:16: error: cannot find symbol
for (number = 1; number <= 5; $++)
^
symbol: variable $
location: class Lab7_Ex1
1 error

Take another look at the tutorial I posted the link to. It shows how to write a for statement to control a loop.
It has examples that you could copy and paste here as a starting point.
NOTE: $ is a valid variable name

Just java right now....told you I was new :D

Then it will be better to copy from a working example instead of trying to make it up.

thats what I am doing.....it doesn't like the $ sign

Lab7_Ex1.java:16: error: cannot find symbol
for (number = 1; number>= 5; $++)
^
symbol: variable $
location: class Lab7_Ex1
Lab7_Ex1.java:20: error: cannot find symbol

Why are you coding a $ in the for statement?
Where do you define the variable named: $

You must define variables before you can use them.

won't let me define it..... this is what I have so far, but its only giving me one dollar sign ($) no matter what number I enter

for (number = 1; number <= 5;)
{
System.out.print("Enter the next number: ");
number = input.nextInt();
System.out.println("$");

}
System.out.print("That is an invalid number.");

Change the loop to ONLY print out the $. Nothing else inside of the loop.
For a simple test do NOT ask for a number, just assign number a value like 7 and execute the loop with that.

Here is a quickie example for ya whome:

Code java:

---

// The variable i is declared and initialized in the loop, which doesn't have to be the case.
for (int i = 0; i < 100; i++) {  // the variable i is what we will increment each iteration while it is less than 100; at which point the loop ends.
  System.out.println(i+1);  // This will print the current value of i + 1 so that it will print the numbers 1-100
}
 
//  So, the things you need for the loop are as follows (in your case at least)
// 1) A variable that will be incremented each iteration
// 2) A starting point, in the example it was 0
// 3) An end point, in the example it was < 100 (which would really be 99)
// 4) Increment the variable
// 5) Do something each iteration; System.out.println(i+1) in the example

---

The basic format would be:
for([incrementVariable] = [startnumber]; [incrementVariable] < [end number]; [incrementVariable]++) {
Do something
}

Note: [incrementVariable] < [end number] <------The equality operator '<' is only used as example and can change based on the situation.

Getting there Norm.....now it just gives me one dollar sign ($) no matter what number I input
int number;
String symbol = "$";


for (number = 1; number <= 5;)
{
System.out.print("Enter a number: ");
number = input.nextInt();
System.out.println(symbol);

}
System.out.print("That is an invalid number.");

Take EVERYTHING out of the loop except for the print statement. Did you miss reading post #16?

that just makes it constantly run.....it needs a value to know what to do

So it is able to print out a 100 or 1million $s now?
Assign it a value for testing. I suggested 7 in post#16.
Later you can ask the user for the number.
