Thread: trouble with making a simple construct for an array of double type

Here is my partial code:

public class Variable {


private double[] array;

public Variable(){
array[0] = 0.0;
}

public String toString(){
return array.toString();
}

public static void main(String[] args) {
Variable Var1 = new Variable();
System.out.println(Var1);
}

And I want to get the following output to simply be:
[0.0]

but for some reason there is still error. What am I doing wrong?

it just keeps prompting me to go to Debug mode, and does not provide a way to correct it, but i know that the error lies in
"public Variable(){
array[0] = 0.0;
}"
b/c that's where the debug first starts

well, i compiled the code many times, and there were no error messages while compiling; only while running.
While running, however, it says that their is a NullPointerException on

<array[0] = 0.0>

Here is the code again. Does this make it easier to figure out?

public class Variable {
 
 
private double[] array;
 
public Variable(){
array[0] = 0.0;
}
 
public String toString(){
return array.toString();
}
 
public static void main(String[] args) {
Variable Var1 = new Variable();
System.out.println(Var1);
}

ohhhhhhhhhhhhhhhhhhhhh I see what I did. i know it was a noob mistake, but thanks!!

Now how would you be able to convert an array into a string?
