described above. for example.

String s = "abc";
System.out.println(s); // this method will output the string, not the address

so how to view the address, thanks in advance.

Java has no concept of "address", so it is impossible to get the address of any object, including strings.

  • thanks. if execute `System.out.println(new int[] {1, 2, 3});`, it outputs `[I@621be5d1`. can the String class output it like that format? – obitoquilt Jul 07 '20 at 04:59

if u want an answer as u mentioned in the comment, Actually there is a way to do it that way.

String s = new String("abc");
System.out.println(Integer.toHexString(s.hashCode()));

this will return

1ae66

This answer was historically accepted as correct and will only work for classes that didn't override the hashCode() method

    System.identityHashCode() gives you always the original implementation :) https://docs.oracle.com/javase/8/docs/api/java/lang/System.html#identityHashCode-java.lang.Object- – Boris Brodski Jul 07 '20 at 08:57
