The difference between a Java constructor and a go constructor

This is a creation in Article, where the information may have evolved or changed.

Because Java constructors do not require a return value, it is generally a constructor that has more arguments than the constructor that calls the parameter, and then continues to assign the value.

Like what:

Public Student (String name) {this.name = name; This.age = 10;}    Public Student (String name, int.) {this (name); This.age = age;}

While the go language requires a return value, it is often a constructor that has fewer parameters, and a default value is passed in when called.

So the code might be like this:

Func newstudentwithage (name string, age int) *student{return &student{name:name,age:age};    }func newstudent (name string) *student{return Newstudentwithage (name, 10); }

The same is true of object-c. If you use C + +, you also write some static functions such as newstudent to call the constructor, it is the same as go.
