Having Problem With "static" When Running a Stand Alone Java Class

Question

I have a Java class that recursively builds a 'tree' . This Java class works as I expected without problem. I am able to write out this 'tree" to the console "line by line" with proper indentation.
The problem occurs when I try to iterate through this 'tree' in the public static void main(String[] arg) method -- Each line in the tree is an Array. And I have to declare this Array (called titleArray in my code) non-static; otherwise, I end up with picking up the very last line of my hard-coded data.
Besides, I also have to declare the List (called recursiveTextArray in my code) non-static; otherwise, I end up with picking up the first Array that I ever build and run into endless iterations till the heap size is exhausted. Note that each element of that List is an Array object.
Then, this non-static Array and this non-static List cannot be accessed in the public static void main(String[] arg) method.
What should I do?
Here is my code that works without problem (the one I do not access the 'titleArray' in the main(String[] arg) method):
import java.util.Iterator;
import java.util.List;
import java.util.ArrayList;
import java.util.Date;
import java.awt.Color;
import com.aspose.words.*;
public class OplanPhase
     public static void main( String[] args)
          OplanPhase root = new OplanPhase( "", "Oplan 50XX - Phase I" );
          OplanPhase objective1 = new OplanPhase( "OO-3.1", "Destroy enemy conventional ground forces" );
          OplanPhase objective2 = new OplanPhase( "OO-3.2", "Destroy enemy conventional air forces" );          
          OplanPhase objective3 = new OplanPhase( "OO-3.3", "Destroy enemy conventional naval forces" );
          OplanPhase objective4 = new OplanPhase( "OO-3.4", "Influence opposition groups within enemy areas to support friendly forces" );
          OplanPhase effect1 = new OplanPhase( "TgtObj-3.1", "Locate, identify, and destroy key enemy C2 nodes" );
          OplanPhase effect2 = new OplanPhase( "TgtObj-3.2", "Locate, identify, and destroy key enemy C2 nodes" );          
          OplanPhase effect3 = new OplanPhase( "CFSOCC-3.2", "influence enemy opposition groups to support friendly forces campaign objectives" );
          OplanPhase effect4 = new OplanPhase( "JFMECC-3.3", "Destroy SLOC interdiction vessels" );
          OplanPhase effect5 = new OplanPhase( "CFSOCC-3.4", "Influence enemy opposition groups to support friendly forces campaign objectives" );     
          OplanPhase moe1 = new OplanPhase( "MOE-TO-3.1", "Conduct surveillance to locate and identify key enemy C2 nodes" );
          OplanPhase moe2 = new OplanPhase( "MOE-JFSOC-3.1", "Degree of cooperative effort with area opposition groups" );
          OplanPhase moe3 = new OplanPhase( "MOE-JFSOC-3.2", "Number of combined missions successfully completed with opposition groups" );
          OplanPhase moe4 = new OplanPhase( "MOE-JFSOC-3.3", "Number of combined missions successfully completed with opposition groups" );
          OplanPhase task1 = new OplanPhase( "TASK-TO-3.1", "Destroy key enemy C2 nodes" );
          OplanPhase task2 = new OplanPhase( "TASK-TO-3.2", "Conduct surveillance to locate and identify key enemy C2 nodes" );
          OplanPhase task3 = new OplanPhase( "TASK-TO-3.3", "Destroy key enemy C2 nodes" );
          OplanPhase task4 = new OplanPhase( "TASK-JFSOC-3.1", "Degree of cooperative effort with area opposition groups" );
          root.addSubLevel( objective1 );
          root.addSubLevel( objective2 );
          root.addSubLevel( objective3 );
          root.addSubLevel( objective4 );
          objective1.addSubLevel( effect1 );
          objective2.addSubLevel( effect2 );
          objective2.addSubLevel( effect3 );
          objective3.addSubLevel( effect4 );
          objective4.addSubLevel( effect5 );
          effect1.addSubLevel( moe1 );
          effect1.addSubLevel( task1 );
          effect2.addSubLevel( task2 );
          effect2.addSubLevel( task3 );
          effect3.addSubLevel( moe2 );
          effect3.addSubLevel( moe3 );
          effect5.addSubLevel( task4 );
          effect5.addSubLevel( moe4 );
          root.outputAllWithIndentation( 0 );
     private String[] titleArray = { "", "", "" };
     private int indentation = 0;
     private List<OplanPhase> subLevels = new ArrayList<OplanPhase>();
     private List recursiveTextArray = new ArrayList();
     public OplanPhase( String foo, String bar )
          titleArray[1] = foo;
          titleArray[2] = bar;
     public void addSubLevel( OplanPhase op )
          subLevels.add( op );
     public void outputAllWithIndentation( int level )
          indentation = level;
          titleArray[0] = indentString( indentation );
         System.out.println( titleArray[0] + "[" + titleArray[1] + "] " + titleArray[2] );
         recursiveTextArray.add( titleArray );
          for ( int i = 0; i < subLevels.size(); i++ )
               ( ( OplanPhase )subLevels.get( i ) ).outputAllWithIndentation( level + 1 );
     private static String indentString( int count )
          String blank = "";
          for ( int i = 0; i < count; i++ )
               blank = blank.concat( "   " );
          return blank;
}And the code below gives me the static and non-static problem:
