java - 有没有办法解决局部变量可能尚未初始化的问题

Question

我收到错误:局部变量可能尚未在以下代码行中初始化

final StingBuilder personSearchURLOne = personSearchURLOne.append(getName.getName1(searchOne));

我无法通过使用 Final StringBuilder personSearchURLOne = null; 进行初始化；起初，因为那样我以后将无法更改它，所以我尝试在我需要它的实例中将其初始化为最终值。它必须是最终的，因为如果不是最终的，我会收到错误:无法引用在不同方法中定义的内部类中的非最终变量。

这是我的另一个类

import android.widget.EditText;

public class getName {
static String nameOne = null;
static String nameTwo = null;

static StringBuilder personURLOne = new StringBuilder();
static StringBuilder personURLTwo = new StringBuilder();

public static String personURL = "http://api.themoviedb.org/3/search/person?api_key=bb0b6d66c2899aefb4d0863b0d37dc4e&query=";

public static StringBuilder getName1(EditText searchOne){
    nameOne = searchOne.getText().toString();


    nameOne = nameOne.replace(" ", "_");


    personURLOne.append(personURL); 
    personURLOne = personURLOne.append(nameOne);



    return personURLOne;

}

public static StringBuilder getName2(EditText searchTwo){
    nameTwo = searchTwo.getText().toString();
    nameTwo = nameTwo.replace(" ", "_");

    personURLTwo.append(personURL);
    personURLTwo = personURLTwo.append(nameTwo);

    return personURLTwo;
}


}

Answer 1

final StingBuilder personSearchURLOne = new StringBuilder(getName.getName1(searchOne));
