Question

So if i have something like this:

public class TestClass {
    public static void main(String[] args) {
        String hello;
        System.out.println(hello);
    }

}

So this would obviously not work. But considering i have such a situation in a program, how can i catch such exception, can you please tell.

Thank you,

EDIT:

So if i have something like this:

class ABC{

   public static String myString;
   public ABC(String myString){
      myString = this.myString;
   }

   public static String getString(){
      return myString;
   }

}

and now if in another class, without calling the constructor of ABC i do like:

 ABC.getString();

This is what i am trying to say… you get it??

Answer 1

As others pointed out, the first case won’t compile.

You should assign a value to the String. null or an empty string are the usual default values.

Consider carefully what would be a logical default value.
Better yet, consider why the code would encounter an uninitialized variable, determine what the value the variable should have (whether a default value or not), and modify your code accordingly.
