如何在 Java追捕未实现的变量例外?
原标题:How can i catch uninitialized variable exception in Java?

因此,如果我有这样的情况:

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

}

因此,这显然不会奏效。 但是,如果在一项方案中考虑这种情况,那么你可以说明如何可以达到这种例外。

感谢你,

EDIT:

因此,如果我有这样的情况:

class ABC{

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

   public static String getString(){
      return myString;
   }

}

而现在,如果是另一类,则不要求ABC的施工者:

 ABC.getString();

这是我试图说的,......你们获得吗?

最佳回答

正如其他人指出的那样,第一起案例汇编了。

你们应当给“努力”分配价值。 <代码>null或空洞是通常的缺省值。

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.

问题回答

是的,这一类并不汇编,因此,你不需要收集。
