How to loop TreeNode of P:treetable data - primefaces

Question

I want to Loop TreeTable object in Java code. Here is by Tree Creation code
public TreeNode getTreeData()
{
lstTestProcessByRelease = testProcessBo.findAllTestProcessByReleaseGroupBy(getTestSuite(), getReleaseByTabName());
List<TestProcess> lstTestScenario = new ArrayList<TestProcess>();
int parentCount=0;
root1 = new DefaultTreeNode(new TestProcess("TestScenario","TestCase",0,0),null);
for(TestProcess tp : lstTestProcessByRelease)
{
parentCount = parentCount + 1;
ExecutionParentOrderValue.put(parentCount, parentCount);
TreeNode parent = new DefaultTreeNode(new TestProcess(tp.getTestScenarioName(), tp.getTestScenarioName(), 0, parentCount),root1);
System.out.println("============"+ tp.getTestScenarioName() +"=================");
System.out.println("Scenario Name (ROWKEY) :"+ parent.getRowKey());
lstTestScenario = testProcessBo.findAllTestCasesByTestScenarioName(tp.getTestSuite(), tp.getReleaseName(), tp.getTestScenarioName());
TreeNode child =null;
int childCount=0;
for(TestProcess tc : lstTestScenario)
{
childCount = childCount + 1;
ExecutionChildOrderValue.put(childCount, childCount);
child = new DefaultTreeNode(new TestProcess(tc.getTestScenarioName(), tc.getTestCaseName(), childCount, parentCount),parent);
System.out.println("TestCase (ROWKEY) :"+ child.getRowKey());
System.out.println("Scenario Name :" + tc.getTestScenarioName());
System.out.println("TestCases Name : " + tc.getTestCaseName());
System.out.println(" TestScenario ExecNo :" + tc.getTestScenarioExecNo());
System.out.println(" TestCase ExecNo :" + tc.getTestCaseExecNo());
}
System.out.println("");
System.out.println("");
}
return root1;
}
If i want to loop root1 object and print data in console, How to do ?
Actually, I want to loop through root1 and get the data from tree and wanted to store in db. But i am not getting and idea how to loop root1 object and get data printed on console.
Could anyone help me on this ?
Thanks
