What value does the equals method return when called multiple times for the same objects?

The equals method in Java, when called multiple times on the same objects, should return true each time if the objects are considered equal according to the implementation's logic. According to the equals contract, the call a.equals(b) should be:

• Reflexive: a.equals(a) is always true.
• Symmetric: a.equals(b) is equal to b.equals(a).
• Transitive: if a.equals(b) and b.equals(c), then a.equals(c).
• Consistent: multiple calls to a.equals(b) return the same value if the objects are not modified.

Example:

String s1 = "test";
String s2 = new String("test");
System.out.println(s1.equals(s2)); // true
System.out.println(s1.equals(s2)); // true on repeated call

Thus, for identical objects, the equals method reliably returns true.
