In which cases is it recommended to use the equals method for comparing objects?

The equals method is recommended for comparing objects when you need to check their logical equality, not just reference equality.

In Java, for example, the == operator checks if two references point to the same object, while equals compares the contents of objects according to certain rules.

Use equals when:

• You want to compare objects by value (e.g., strings, custom classes with overridden equals).
• Objects may have the same data but different references.

Example:

String a = new String("test");
String b = new String("test");

System.out.println(a == b); // false, different objects
System.out.println(a.equals(b)); // true, same content

If the class does not override equals, it inherits the behavior from Object, which compares references.
