java - How to use "this" keyword to invoke multiple constructs with more than 1 arguments in the class? -

i studying this() keyword invoke constructors. pretty sure simple mechanism used invoke current class's other constructor:

public class ascaller { string name; int id;  ascaller() {     system.out.println("no arguments"); } ascaller(string n, int i) {     this();     name = n;     id = i; }  void display() {     system.out.println(id + " " +name); }  public static void main(string[] args) {     ascaller example1 = new ascaller("student", 876);            example1.display();   } } 

as expected gives output of:

no arguments 876 student 

but, if have more 2 constructors , of them having 2 or more arguments. how this() keyword used invoke 1 of them? like:

public class ascaller { string name; int id;  ascaller(string city, string street, float house) {     system.out.println("float datatype invoked"); }  ascaller(int age, int marks) {     system.out.println("int datatype invoked"); }  ascaller(string n, int i) {     // how use this() keyword invoke of above constructor?.     this();     name = n;     id = i; }      ascaller() {     system.out.println("no arguments");    } void display() {     system.out.println(id + " " +name); }  public static void main(string[] args) {     ascaller example1 = new ascaller("student", 876);      example1.display();     } } 

i think doesn't make sense call 2 constructors constructor. kind of constructors coder coding class chooses provide design choice , can made not need call 2 constructors 1 constructor. think reason java allows call 1 constructor constructor since there might default initialization default constructor might do, opening socket, allocating memory etc might common across constructors. rewrite code follows don't have call 2 constructors 1 constructor though functionality preserved.

    public class ascaller {     string name;     int id;        void intinit(int age, int marks){         system.out.println("int datatype invoked");     }     void floatinit(string city, string street, float house){         system.out.println("float datatype invoked");     }     ascaller(string city, string street, float house) {         floatinit(city,street,house);     }      ascaller(int age, int marks) {         intinit(age,marks);     }      ascaller(string n, int i) {       // how use this() keyword invoke of above constructor?.         this();         intinit(1,2);         floatinit("a","b",3.0f);         name = n;         id = i;     }      ascaller() {         system.out.println("no arguments");     }     void display() {         system.out.println(id + " " +name);     }      public static void main(string[] args) {         ascaller example1 = new ascaller("student", 876);          example1.display();     }       } 

tl;dr: no, compiler won't allow call 2 constructors constructor of class since call must first statement in constructor.
