Java: how to access a field from a nested class?

Question

Java

class Test {
  private String outerString = "КО КО КО";
  class innerTest {
    Test.this.outerString = "ПОК ПОК ПОК";
  }
}

How can I access a field in an outer class from a nested class?

Answer 1

You are trying to perform an assignment at the class definition level, which is interpreted by the compiler as an attempt to declare a Test.this.outerStringclass field innerTest, which is naturally impossible. And inside any method you will not have access problems

class innerTest {
    void someMethod() {
        Test.this.outerString = "ПОК ПОК ПОК";
        // или даже проще
        outerString = "ПОК ПОК ПОК";
    }
}
