this is current object.
[b]this key word ante when you create an instance of a class in the same class you can refer all variable by this[/b]
u can also refer constructors by this
also methods by this. This is for that object in which the sangarshana is going on at that time. This mean current object
Super means super class this object

Wonderful explanation. In Class A { }, I am writing this.name = name. As the JVM is creating the object before it is executing this method in class A, it knows that [b]this.name[/b] belongs to object of class A.
But I never know we can invoke methods using "this"

endhuku this ani vadatham thelsa
manaki java lo class owned variables untai vatini static antam

[b]ante this anedhi object owened when referring its own members[/b]

Vere clas lo aithe

[u][color=#000000][font=Arial,]Within an instance method or a constructor, [/font][/color]this[color=#000000][font=Arial,] is a reference to the current object — the object whose method or constructor is being called. You can refer to any member of the current object from within an instance method or a constructor by using this.[/font][/color][/u]



Naku ardaminantha varaku, in a setter method, we say something like
this.name = name;

In my understanding, [b]this.name [/b]referes to the instance variable and [b]name [/b]refers to the argument parameter.
But, the above underlined statement, says that [b]this [/b]is a reference to the current object.
What does it mean to us ? If it is a reference to the current object, what we ll get out of it ?

Please help.

[b]Q1)But, the above underlined statement, says that this is a reference to the current object.
What does it mean to us ?[/b]

Ans: current object ki memory lo oka address untadi something like #627282
so mana this ane variable lo ee address vostadi when this is used , and so we can modify the object at that point in runtime
so thats why "this" is always a reference



[b]Q2)If it is a reference to the current object, what we ll get out of it ?[/b]

Ans: If it is a reference we can make changes to that object directly in the memory;

Let me know if you have more questions i can explain clearly
