本文通过一个具体的Java程序示例，展示了类之间的继承关系及其构造函数的调用顺序。父类Father和子类Children的构造函数被依次调用，并且创建了Mother类的一个实例。

[size=large][color=blue]
package test;

class Test {
 public static void main(String[] args) {
  new Children();
 }
}

class Mother {
 public Mother() {
  System.out.println("This is Mother");
 }
}

class Father {
 public Father() {
  System.out.println("This is Father");
 }
}

class Children extends Father {
 public Children() {
  System.out.println("This is Children");
 }

 Mother mother = new Mother();
}

输出结果：

This is Father
This is Mother
This is Children[/color][/size]
