How to throw RuntimeException (“cannot find symbol”)

Question

I\'m trying to throw an exception in my code like this:

throw RuntimeException(msg);

But when I build in NetBeans I get this error:

<         


        

Answer 1

using new keyword we always create a instance (new object) and throwing it , not called a method

throw new RuntimeException("Your Message");

You need the new in there. It's creating an instance and throwing it, not calling a method.

int no= new Scanner().nextInt();   // we crate an instance using new keyword and throwing it 

using new keyword memory clean [because use and throw]

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {

        //do your work here..
    }
}, 1000);
