This with constructor

Example

class student{
    int id;
    String name;
			 
	student(){
	   System.out.println("Hello  Everyone");
	}
			 
	student(int id,String name){
	    this.student();           //this  used with constructor
		                          //It refer constructor which declare above this code
	    this.id=id;
	    this.name=name;
	}		  
			
	void show(){
	  System.out.println(id+" "+name);
	} 
			   
	public static void main(String args[]){
	   student s=new student(123,"max");  //this constructor call parametrized constructor
	   s.show();
	}
}
				
	
          

output:
Hello Everyone                     //Initially it calls defualt constructor due to this
123 max                            //then it will display value of parametrized constructor
