You don't have to provide any constructors for your class, but you must be careful when doing this. The compiler automatically provides a no-argument, default constructor for any class without constructors. This default constructor will call the no-argument constructor of the superclass. In thi...

By convention, class Throwable and its subclasses have two constructors, one that takes no arguments and one that takes a String argument that can be used to produce a detail message. Further, those subclasses that might likely have a cause associated with them should have two more constructor...
First of all, let’s create a simple Java class: public class Outer { // variables and methods... } When we compile theOuterclass, the compiler will create anOuter.classfile. In the next subsections, we’ll add nested classes in theOuterclass and see how class files are named. ...
full constructor是完整构造函数,用于平时的new XXX(参数1的类型 参数1变量,参数2的类型 参数2变量,……) 构造方法作用就是对类进行初始化。 如果你没有定议任何构造方法的形式,程式会为你取一个不带任何参数的构造函数,那么你产生类的对像时只能用不带参数的方法,如:class a {}//没有任何构造函数。
