Hi guys. I wondering a thing, which is there any future of programming language, which when we run our app and to see that where happened our error? For example if we assign string to integer it is easy that detect our error, but runtime it is difficult.

What I have tried:

I nothing tried to searching, because it is difficult question.

May be time to break the debugger.

Your code do not behave the way you expect, or you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your code is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

The debugger is here to only show you what your code is doing and your task is to compare with what it should do.

You tagged this as a Java question. Java is typed, so assigning a string to an integer isn't possible.

Most software errors are logic errors. The software isn't doing anything illegal. It's just not doing what you intended, but there's no way to automatically detect that. Only you know what your app is supposed to do, so only you can say that an error occurred. And then it's as Patrice said: you need to use the debugger to find out where your app is doing something that you didn't expect.
