未处理的异常java.net.malformedurlexception

Question

How come this code is giving me a unhandled exception java.net.malformedurlexception in java ?

String u = "http://webapi.com/demo.zip";
URL url = new URL(u);

Can someone tell me how to fix?

Answer 1

You need to handle the posible exception.

Try with this:

    try {
        String u = "http://webapi.com/demo.zip";
        URL url = new URL(u);
    } catch (MalformedURLException e) {
        e.printStackTrace();
    }

Answer 2

Use a try catch statement to handle exceptions:

String u = "http://webapi.com/demo.zip";
try {
    URL url = new URL(u);
} catch (MalformedURLException e) {
    //do whatever you want to do if you get the exception here
}

Answer 3

 java.net.malformedurlexception

It means that no legal protocol could be found in a specification string or the string could not be parsed or your URL is not confirmed the spec or missing a component I think this will help you to understand URL
