What is use of default constructor and constructor???

Answer 1

default constructor is the constructor that has no arguments. it gets called and the object is instantiated with default parameters when there is no arguments.

class Animal (){
public name;

public void Animal(){
// default constructor
this.name="tiger";
}

public void Animal( String name){
this.name=name;
}

}

in this case if you don't put name of animal it will automatically set the name of animal as tiger.
