The differences between constructors and ordinary functions are as follows:

1. Differences in writing

Construction method:

public(修饰符) class(定义类的关键字) Test(类名)(){ //无参 Test(类名)(){ } //带一个参数 Test(类名)(String(变量类型) name(变量名)){ } }
Copy after login

(Video tutorial recommendation:java video)

Common method:

//定义类 public(修饰符) class(定义类的关键字) Test(类名)(){ private(修饰符) static(修饰符) String(变量类型) s(变量名) = “hello world”; //下面是方法的定义 public(修饰符) static(修饰符) void(返回值类型) main(方法名)(String[] args(参数)){ System.out.println(s);(代码语句) } }
Copy after login
