Question

In certain cases I want my function to simply crash and my app to stop execution:

public void foo() {
    if(lifeIsWorthLiving) {
        /*code ...*/
    }
    else {
        /* log the problem, throw an exception and die */ 
    }
}

Now if I add throw Exception("lifeIsWorthLiving = false !!!"); then I need to add throws Exception to function definition and then I have to handle this everywhere I call foo(). I don’t want to do that. How can I do this?

Answer 1

Throw an RuntimeException or maybe Error, depending on the nature of the problem. Both doesn’t need to be declared in a throws. Last alternative is to call System#exit().
