selenium code to select radio button

Am doing automation tesing using selenium, i need help in regarding how to select radio button.If possible help me with selenium java code.

How do you select radio button in Selenium?

Also, we can select Radio buttons by using the click() method. Selenium also offers validation methods like isSelected(), isEnabled() and isDisplayed(). We can use these methods before performing any operation to make sure radio buttons are in the correct state.

Assuming you have selenium set up its just:

selenium.click('radio button locator');

You may want to look at the selenium javadoc http://release.seleniumhq.org/selenium-remote-control/0.9.2/doc/java/com/thoughtworks/selenium/Selenium.html

click > xpath=(//input[@type='checkbox'])[position()=1]
click > xpath=(//input[@type='checkbox'])[position()=2]
click > xpath=(//input[@type='checkbox'])[position()=3]
click > xpath=(//input[@type='checkbox'])[position()=4]

etc ... use this commands to select random and any radio button
