Problem compiling

[Katie Smith]

Hi,
I'm trying to compile this program that I got from my teacher, but I keep getting errors. Here is the code:

public class Family {
	private double income;
	private int size;
	
	public Family() {
		income = 0;
		size = 0;
	}
	
	public Family( double income, int size ) {
		if( income > 0 )
				this.income = income;
		if( size > 0 )
				this.size = size;
	}
	
	public boolean isPoor( double housingCost, double foodCost ) {
		if( housingCost + foodCost * size > income )
			return true;
		return false;
	}
	
	public String toString() {
		return “Family of size ” + size + " has income " + income;
		}
	}

The last few lines are causing the problem (the "public String toString" part). I don't think that the return command likes the combination of strings, doubles, and integers. Any ideas?

Hint: carefully inspect the characters you used.

These were the errors:

String

Thanks!

It'd be best to copy and paste the error messages exactly as displayed, and UseCodeTags to preserve the formatting. Also be sure to UseCodeTags for your code. I added them to your original post.

In any case, look carefully at the quote characters on line 24. See anything amiss?

I know it's having a problem with the quotation marks, but it seems like I have matching sets and I've used double quotes before, so I'm really not sure what the problem is. Can you help?

[Katie Smith]

I erased and rewrote the code for that part, and now the first quote block shows up blue like the other one. I hit save, and the error message went away. I'm still interested in understanding what you were seeing in the character. But the code seems to be working now, so thanks!

[Bear Bibeault]

The characters used to delimit the first string are not double quote characters. They are "smart quote" characters from a word processor. They are not valid to use in Java.

Did you use Word or some other unsuitable program to type this code in? Or is this how you received it from the teacher? If the latter, he or she is being very sloppy.

That explains it! Thank you! I copied the code from a word document my teacher sent us. That explains why when I erased and retyped it, the quotes worked. Thanks, again!
