Java - String == (Reference Comparison) vs .equals() (Value Comparison)
In Java, == and .equals() serve different purposes:
== (Reference Comparison): This checks whether two variables point to the same memory location. If two objects have the same reference, == returns true.
.equals() (Value Comparison): This method is used to compare the actual content of objects. For example, when comparing two String objects, .equals() checks whether their text values are the same.
Example:
String a = new String("hello");
String b = new String("hello");
System.out.println(a == b); // false (different memory locations)
System.out.println(a.equals(b)); // true (same content)
