Explain the difference between == and .equals() in Java.
← All Java (Android) questions
Re-explain
- == compares memory addresses (reference equality) for objects, and actual values for primitives.
- .equals() compares the actual content/values of objects.
String s1 = new String("Hello");
String s2 = new String("Hello");
String s3 = "Hello";
String s4 = "Hello";
System.out.println(s1 == s2); // false (different objects)
System.out.println(s1.equals(s2)); // true (same content)
System.out.println(s3 == s4); // true (string pool)
