声明Java对象数组

Question

我有以下代码，我已多次修改：

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);

这里发生了什么，eclipse试图对我说什么？

Answer 1

陈述

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

应该在代码块中，例如方法，构造函数或实例初始值设定项
