java - java中静态变量和非静态变量一起添加

Question

在java中我们可以将静态变量和非静态变量一起添加吗？例如，

class Evolve{
    static int i = 1;
    static int j = 2;
    int x = 3;
    static int y = 6;

    public static void main(String args[]){
        System.out.println(i + j);
        System.out.println(x + i);
        System.out.println(i + y);
        System.out.println(x + j);
    }
}

谢谢

直到您初始化 Evolve 实例并将其引用为

this.i

或者像这样

Evolve evolve = new Evolve();
System.out.println(evolve.i + Evolve.j);
