inheritence questions

[mac]

First

public abstract class PreSetter {
	public StringBuffer sourceFile = new StringBuffer("aa");
}

Then

public class Main extends PreSetter {
	sourceFile.append("hello");
}

Then

public class Arguments extends PreSetter {
	System.out.println(sourceFile); // blank. Why?
}

I thought that when using PreSetter class, i am crearing a new Object sourceFile, reference of which is accessed by Main, and assigned value "hello".
Class Arguments later attempt to print out that reference, but it seems as if it is being "new"(ed) and assigned "aa" on access.

Can you help me understand this?

Your code doesn't compile so I'm not sure how you're calling things. You may want to post a small bit of code that compiles and runs and demonstrates your problem. e.g.,

public class MacTest {
  public static void main(String[] args) {
    System.out.print("Arguments: ");
    new Arguments();
    System.out.print("Arguments2: ");
    new Arguments2();

  }
}

abstract class PreSetter {
    public StringBuffer sourceFile = new StringBuffer("aa");
}

class Main extends PreSetter {
  
  Main() {
    sourceFile.append("hello");
  }
}

class Arguments extends PreSetter {
  Arguments() {
    System.out.println(sourceFile); 
  }
}
