[Solved] java need a child object to change data in the parent [closed]

by


How do I send a stream of data back to the “parent” or calling instance / object?
“parent” is not the right word here, as ccc doesn’t extend bbb.

Suppose your class bbb has a field data which you want to update:-

class bbb{
 private String data;

 public String getData(){
  return data;
 }

public void setData(String data){
this.data=data;
}
}

In your your class bbb, there is a call to a method by ccc instance, which need to update data field of bbb :-

ccc doStuff = new ccc(this);
doStuff.goAndConquer()

Your class ccc will look like below:-

class ccc{

private bbb b;

public ccc(bbb b){
  this.b=b;
}

//Now while processing your file just do below
// b.setData(dataToBeSet);

}

Just pass the instance of bbb to ccc and update it.
