Declaring Java object array

Question

I have the following code, that i have revised multiple times:

public class double3 {
    public double x=0;
    public double y=0;
    public double z=0;
    public double3(double a, double b, double c){
        this.x=a;
        this.y=b;
        this.z=c;
    }
}


double3[] samples = new double3[4];//syntax error on token ";", { expected after this token
samples[0]=new double3(1,2,3);

What is happening here and what is eclipse trying to say to me?

The statements

double3[] samples = new double3[4];
samples[0] = new double3(1,2,3);

should be in a code block such as a method, constructor or instance initializer

Right, because Java is unlike scripting languages such as Javascript that allow for arbitrary execution of code outside of methods. A main method is needed to kickstart the process.

Yes! Dumb error of me. It was actually inside a bigger and lengthy class, and my previous C experience doesn't warn me about this things. Thank you! (I will accept when allowed to)

Note that Java classes start with an uppercase letter, e.g. Double3 - read more here

Actually its the statement: samples[0] = .... It expects to find it in a code block so its expecting the brace {

It doesn't expect it after the semicolon, it expects a brace before the semicolon but gets the semicolon first and chokes.
