In Java, == compares memory addresses while .equals() compares the actual content of objects.
== compares memory addresses of objects, while .equals() compares the actual content.
== is used to compare primitive data types, while .equals() is used to compare objects.
Example: String str1 = new String("hello"); String str2 = new String("hello"); str1 == str2 will be false, but str1.equals(str2) will be true.
The question explains the difference between == and .equals() in Java for comparing object references and content.
Use == to compare object references (memory location)
Use .equals() to compare the actual content or values of the objects
Example: String str1 = new String("hello"); String str2 = new String("hello"); str1 == str2 will be false, but str1.equals(str2) will be true

In Java, == compares object references, while .equals() compares object values.
Use == to compare if two object references point to the same memory location.
Use .equals() to compare if two objects have the same values.
Example: String str1 = new String("hello"); String str2 = new String("hello"); str1 == str2 will be false, but str1.equals(str2) will be true.
