well this subforum is for roblox lua, but maybe if you're lucky agentfirefox (or someone else who is good with java) may come along and see this.

I don't know very much java, but it might be because temperature is private, and cannot be accessed within a function?

And maybe you need to remove the final }, that might help.

New code? :

private int temperature;


public String temperature (int temperature)
{
if (temperature < 0){
return "You need a jacket or you will die";
}else if (temperature < 32){
return "SUPER COLD";
}else if (temperature < 64){
return "Chilly";
}else if (temperature < 80){
return "Warm";
}else if (temperature < 100){
return "Burning";
}else if (temperature < 1000){
return "You are dead lol";
}else
return "N/A";

return temperature;
}
}

You missed the class definition for your method:

public class temperature{
public static void main(int temperature){
// Your code
}
}

Let's first look at the function to see what's wrong.



public String temperature (int temperature)
{
if (temperature < 0){
return "You need a jacket or you will die";
}else if (temperature < 32){
return "SUPER COLD";
}else if (temperature < 64){
return "Chilly";
}else if (temperature < 80){
return "Warm";
}else if (temperature < 100){
return "Burning";
}else if (temperature < 1000){
return "You are dead lol";
}else
return "N/A";

return temperature;
}


The first thing to notice is the fact that, not only is 'return temperature' not going to be reached, but it isn't even valid. This is because your defined your method as returning a String, whereas temperature is an int.

Now, let's tack on your private variable.



private int temperature;


public String temperature (int temperature)
{
if (temperature < 0){
return "You need a jacket or you will die";
}else if (temperature < 32){
return "SUPER COLD";
}else if (temperature < 64){
return "Chilly";
}else if (temperature < 80){
return "Warm";
}else if (temperature < 100){
return "Burning";
}else if (temperature < 1000){
return "You are dead lol";
}else
return "N/A";

//return temperature; -- commented out
}


Now we look at the function in relation with your private variable. Specifically, your function will not use the private variable when accessing temperature. This is because you shadowed the private variable with a local variable within the function (as a parameter). Which means your private variable is useless in this situation.


Last of all, you do not have the definition of your class, as noted by DrMathematica.



/*
* File Temp.java
*/
public class Temp {

public static void main(String[] args) {
int temp = Integer.parseInt(args[0]);
Temp t = new Temp();
System.out.println(t.temperature(temp));
} // end main method

public String temperature(int temperature)
{
if (temperature < 0){
return "You need a jacket or you will die";
}else if (temperature < 32){
return "SUPER COLD";
}else if (temperature < 64){
return "Chilly";
}else if (temperature < 80){
return "Warm";
}else if (temperature < 100){
return "Burning";
}else if (temperature < 1000){
return "You are dead lol";
}else
return "N/A";
} // end temp method

} // end class



I'm going to eat right now, but I'll check back here when I'm done.

"he's like santa."

Yes. I see you when you're sleeping. I know when you're awake.
I know if you've been bad or good. ( ͡º ͜ʖ ͡º)

So be good, for goodness sake!

You should probably add a geater thanidentifyer in your temperature checks because if say it was below 0 then it could return any one of those strings.

All of that needs to be inside a class.
Did you use my example and name the file 'Test.java' ?

Also. I am new to m y computer science class so this can't look like it was made by an expert. I used when I basically knew in the original code. Aren't there just a couple of small fixes I can do? Oh and this is a method, not a class.

This has no syntax errors but it wants me to enter a string for temperature. I want to enter and int and have a string returned.....

public int temperature(String temperature, int temp)
{
if (temp < 0){
return "You need a jacket or you will die";
}else if (temp < 32){
return "SUPER COLD";
}else if (temp < 64){
return "Chilly";
}else if (temp < 80){
return "Warm";
}else if (temp < 100){
return "Burning";
}else if (temp < 1000){
return "You are dead lol";
}else
return "N/A";
}

}

It had an error that said enum interface or class expected by the last bracket. This is all part of a bigger code btw.

Semicolon!!
But I doubt that'll be the problem. I know JavaScript, but only the strict basics, so I can't really help you a lot here. Sorry.
