Android Java 内部方法如何给外部方法的变量赋值？

会提示错误 Variable 'sourceCode' is accessed from within inner class, needs to be final or effectively final外部常量加了final后会提示错误 Cannot assign a value to final variable 'sourceCode'

把sourceCode放到方法外面去

public class net{
   private static String sourceCode = null;
    
}

定义成员变量(类变量)，不要定义成局部变量。
