public class classA implements interfaceA {

  @Override
  public Optional<T> methodA(String s) {
    return (this).methodA(s); // <-  IDEA doesn't underlines as recursion
  }

  @Override
  public Optional<T> methodB(String s) {
    return (this).methodB(s); // <- IDEA doesn't underlines as recursion
  }

public class classA implements interfaceA {

  @Override
  public Optional<T> methodA(String s) {
    return this.methodA(s);  // <-  IDEA underlines as recursion
  }

  @Override
  public Optional<T> methodB(String s) {
    return this.methodB(s); // <- IDEA underlines as recursion
  }

我还没有见过这样的形式。任何人都可以链接到文档的参考或解释通常形式和括号之间的区别吗？
