Calling Parameterized Method from one class to another class

Question

Hi, below is my sample code
test.java
public class test
     int op1[][]=new int[][]{{1,2},{2,3},{4,5}};
     int row=0;
    public void  test() {
          int op2[][]=new int[][]{{2,3},{4,5},{6,7}};
                         row=1010;
          getRow(row);
    int[][] getList()
         return op1;
   public  int getRow(int klm)
         System.out.println("Row Value in GetRow Method  is:     "+row);
         return klm;
test_2.java
package aa;
public class test_2
int a;
     test t11=new test();
     int abc[][] = t11.getList();
     int rowCount=t11.getRow(a);
     public void test_2()
          System.out.println("Row Value is:     "+rowCount);
          System.out.println("Value in abc[1][1] is:     "+abc[0][1]);
main_class.java
package aa;
public class main_class {
     public static void main(String args[])
          test ab=new test();
          ab.test();
          test_2 ba=new test_2();
          ba.test_2();
    public main_class() {
}now that my question is,for 'rowCount' in class test_2.java i need to get the value of 'row'(which is 1010)from class test.java. How could that be done?
Any reply is highly appreciable.
Thanks in advance

hmm, i did chaged the test object in main method to same as the test object that i used in test_2 (ie; i changed test ab=new test() in main_class.java to test t1=new test()).What? How does this help?
Again, simplify the problem
For instance, say you have a class, Fubar1, like so:
class Fubar1
  int value = 0;
  public void setValue(int v)
    value = v;
  public int getValue()
    return value;
}and two different Fubar2 classes, both which try to get the value from Fubar1, one doing it badly:
class Fubar2Bad
  Fubar1 f1 = new Fubar1(); // totally internal Fubar1 object
  public int getFubar1Value()
    return f1.getValue();
}and one that does it well, that holds a reference to whatever Fubar1 object is passed to it:
class Fubar2Good
  Fubar1 f1;
  public Fubar2Good(Fubar1 f1)
    this.f1 = f1;
  public int getFubar1Value()
    return f1.getValue();
}Then if you test these:
public class TestFubars
  public static void main(String[] args)
    Fubar1 f1 = new Fubar1();
    f1.setValue(35);
    Fubar2Bad f2Bad = new Fubar2Bad();
    Fubar2Good f2Good = new Fubar2Good(f1); // here we pass a reference to the main's Fubar1 object into the Fubar2Good object.
    System.out.println("Bad: " + f2Bad.getFubar1Value());
    System.out.println("Good: " + f2Good.getFubar1Value());
}
