Q:

Java language : "this" keyword usage (used in Talend tJavaRow)

In Talend i was writing up some small code, a class in the MetaData "code" area, one can code ones java Class then in the component tJavaRow, one can call upon the methods of the class.
So i ran into the situation when i made the class and wrote in tJavaRow the name of the Class then a dot, the context dialog that came up did not show the methods, but showed the "this" keyword along with other things.
I decide to use 'this' then put a dot and then the context dialog came up to show the methods in the class.
My question is does the keyword 'this" have the ability to implicitly instantiate a class into an object, and hence that is why i was able to see the methods of the class?
I just decided to change one of my methods to a static method and use it that way.
So if it is correct that the keyword 'this' can instantiate a class to an object without using 'new' keyword to instantiate java class to an object?
I did some research on this, i found this list of things that the keyword 'this' can do.

Usage of this keyword

It can be used to refer current class instance variable.
this() can be used to invoke current class constructor.
**It can be used to invoke current class method (implicitly)**
It can be passed as an argument in the method call.
It can be passed as argument in the constructor call.
It can also be used to return the current class instance.

So to put some code example to illustrate:
Say we have a class called mySphere, and we have methods mySurfaceArea and myVolume, could we call the method in this manner:

mySphere.this.mySurfaceArea();
mySphere.this.myVolume();

Input is appreciated!
I just created my own code on this and ran it, and i got an error:
public class MyClass {
    public static void main(String args[]) {
        int x=10;
        int y=25;
        int z=x+y;
        int w;

        System.out.println("Sum of x+y = " + z);
        w = MyClass.this.myAreaCalc(x);
        System.out.println("Area Calc is = " + w);
    }
    
    public int myAreaCalc(int A){
        return A*A;
    }
    
}

Error:
/MyClass.java:9: error: non-static variable this cannot be referenced from a static context
        w = MyClass.this.myAreaCalc(x);
                   ^

A:

<ClassName>.this is a shortcut for the this object WHILE you are in the class context.
Since you are inside the static context of public static void main you canno't access non-static instances from here.
Your code needs to instantiate a object of the class and use its non static methods trough the instance object.
public static void main(String args[]) {
    int x=10;
    int y=25;
    int z=x+y;
    int w;

    System.out.println("Sum of x+y = " + z);
    w = new MyClass().myAreaCalc(x);
    System.out.println("Area Calc is = " + w);
}

The usage of <ClassName>.this is the reference to the outer class in such case:
public class A {
    class B {
        void x () { A outer = A.this; }
    }
    B create() { return new B(); }
}

In this case only from inside the instance context of A you can create a object of B in the example with the usage of B b = new A().create() or for answering your question about contexts
A ao = new A();
B b = ao.new B();

Also the usage of ClassName.this on anonymous and child classes are used for variable distinction if you have the same name in both instance contexts.
