running testng programmatically Need loop to create multiple test automatically

My code is below. I was wondering if someone can give me the right direction for this. Not sure if I'm using Map or hashmap correctly for loop. I know it works if I do one parameters but I like to do 1-100 host parameters when I create my XML programmatically. Can you show me what I need to do for creating a loop so I can create multiple test with parameter with host value 1-100.

package firsttestngpackage;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.TestNG;
import org.testng.xml.XmlClass;
import org.testng.xml.XmlSuite;
import org.testng.xml.XmlTest;

public class Test1 {

    WebDriver driver;
    WebDriverWait wait;

    private void testRunner(Map<String, String> testngParams) {
        TestNG testNG = new TestNG();
        XmlSuite suite = getXmlSuite();
        XmlTest test = getXmlTest(suite);
        test.setParameters(testngParams);
        List<XmlClass> classes = getXmlClasses();
        test.setXmlClasses(classes);
        List<XmlTest> tests = new ArrayList<XmlTest>();
        tests.add(test);
        suite.setTests(tests);
        List<XmlSuite> suites = new ArrayList<XmlSuite>();
        suites.add(suite);
        testNG.setXmlSuites(suites);
        testNG.run();
    }

    private XmlSuite getXmlSuite() {
        XmlSuite suite = new XmlSuite();
        suite.setName("Test Suite");
        return suite;
    }

    private XmlTest getXmlTest(XmlSuite suite) {
        XmlTest test = new XmlTest(suite);
        test.setName("test_with_firefox");
        return test;
    }

    private List<XmlClass> getXmlClasses() {
        List<XmlClass> classez = new ArrayList<XmlClass>();
        classez.add(new XmlClass("firsttestngpackage.Test5"));
        return classez;
    }

    public static void main(String args[]) {

        Test1 program = new Test1();
        Map<String, String> params = new HashMap<String, String>();

        //Need THIS CONFIGURATION LOOP TO WORK
        //NEED HELP HERE!!!!!!!!!!!!!!
        for (int hostnum = 1; hostnum <= 100; hostnum++){
            params.put("host", hostnum);
        }

        //THIS CONFIGURATION WORKS, BUT NO LOOP
        //params.put("host", "10");
        program.testRunner(params);
    }
}

This is the Expected XML but 100 times

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://ift.tt/19x2mI9">
<suite name="TestSuite" thread-count="3" >
  <test name="1">
  <parameter name="host" value="1" />
    <classes>
       <class name="firsttestngpackage.Test5">
       </class>
    </classes>
  </test>
  <test name="2">
  <parameter name="host" value="2" />
    <classes>
       <class name="firsttestngpackage.Test5">
       </class>
    </classes>
  </test>
  <test name="3">
  <parameter name="host" value="3" />
    <classes>
       <class name="firsttestngpackage.Test5">
       </class>
    </classes>
  </test>
 </suite>

I am getting syntax error
