java call constructor without parameters from constructor with parameters

Question

I have the next question. I have the code:

public class Foo {
  private int x;

  public Foo() {
    this(1);
  }

  public Foo(int x) {
    this.x = x;
  }
}

Can I call from Foo(int x) Foo() somehow?

Answer 1

您不能-这样做（调用this() ）会在构造函数之间创建循环依赖关系，而这在编译时是不允许的
