How to Define Menu Hierarchy in XML in Android

Here is source code of the Program to Demonstrate Defining Menu Hierarchies in XML in Android. The program is successfully compiled and run on a Windows system using Eclipse Ide. The program output is also shown below.

Main Activity

package com.example.menuhirachies;
 
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
 
public class MainActivity extends Activity {
 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
 
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }
 
}

menu

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
 
    <item
        android:id="@+id/action_settings"
        android:orderInCategory="100"
        android:showAsAction="never"
        android:title="@string/action_settings"/>
    <item
        android:id="@+id/item02"
        android:checkable="true"
        android:title="menu_item_two">
    </item>
    <item
        android:id="@+id/item03"
        android:alphabeticShortcut="3"
        android:numericShortcut="3"
        android:title="menu_item_three">
    </item>
    <item
        android:id="@+id/item04"
        android:title="submenu">
        <menu>
            <item
                android:id="@+id/item05"
                android:title="submenu_item">
