Note:
Java was developed by Sun Microsystems (which is now a subsidiary of Oracle) in the year 1995. James Gosling is known as the father of Java. Before Java, its name was Oak. Since Oak was already a registered company, James Gosling and his team changed the name from Oak to Java.

Thank you again.

Comparing String using == and .equals() method.
Both equals() method and the == operator are used to compare two objects in Java. == is an operator and equals() is method. But the == operator compares the reference or memory location of objects in a heap, whether they point to the same location or not.
Whenever we create an object using the new operator, it will create a new memory location for that object. So we use the == operator to check memory location or address of two objects are the same or not.

We can use == operators for reference comparison (address comparison) and .equals() method for content comparison. In simple words, == checks if both objects point to the same memory location whereas .equals() evaluates to the comparison of values in the objects.
