getting version number from user-agent

[Jim Haley]

I'm looking for a way to check the version number in the user-agent. I would like to get the version numbers so I can test if the version is greater than 5.1. Once 5.1.1 or 5.2 roll out I don't want to adjust my code. I was looking into using regular expression but was having some problems. Thoughts?

Here two examples of 2 user-agent strings

Mozilla/5.0 (iPad; U; CPU OS 4_3_5 like Mac OS X; en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8L1 Safari/6533.18.5

Mozilla/5.0 (iPad; CPU OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3

This is not about regex or any thing else, just it is a logic you have to think about it, you can get your output in many ways here it is one way you can achieve it

public class Test {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		
		String string = "Mozilla/5.0 (iPad; CPU OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3";
		String[] arrString= string.split(" ");
		
		for (int i = 0; i < arrString.length; i++) {
						
			if(arrString[i].matches(".*Version.*")){
				String version = arrString[i].split("/")[1];
				System.out.println("this is wat u wanted  "+version);
								
			}
		}
						
	}

}
