I want to judge whether the addresses of the two objects are the same. What is the use of pointers?

Then just use ==
‘==’ is based on whether their addresses are the same

public class StringTest {
  public static void changeStr(String str){
    str="bbb";
    if (str== ???) //Here I want to compare with String str in the main function. How do I write this sentence? ?
I just wanna do this
        System.out.println("==");
  }

  public static void main(String[] args) {
    String str="aaa";
    changeStr(str);
    System.out.println(str);
  }
}
