Triangle type issue

[Laharl]

Your problem is that you never actually assign triangleType, the string data, to be equal to the return value of triangleType(), the function. So every time you print triangleType the variable, you get null since you never defined it to be anything.

Make triangleType private and call it as part of your constructor, with a statement like

[code=java]
triangleType = triangleType(s1 , s2, s3);
[/code]

I tried changing triangleType to private and I get an error and the same result "null". How do I go about making it private? Yeah, I know you change public to private, but I apparently can't do anything right with this.

Changing the access modifiers has nothing to do with it.
Go through your code and dry run it. At each statement write down the values of all the variables.

if(side1 == side2 && side2 == side3)
type = "Equilatera l";

else if(side1 == side2 && side2 != side3)
type = "Isoscelese ";

else if(side1 == side3 && side2 != side3)
type = "Isoscelese ";

else if(side1 != side3 && side2 == side3)
type = "Isoscelese ";

else
type = "Scalene";

return type;
[/CODE]

what do != and == mean?

what do != and == mean?

a != b means "a is not equal to b" while "a == b" is the exact opposite. You can however only reliably compare primitive objects (e.g. int, double, boolean,...) with these, not Objects (e.g. String, Thread, Exception,...).

Just a tip: To compare Objects, you would have to use the equals method. This article shows you how to do that for your own classes.
