Can you use == to compare strings in Java?

equals() method and == operator is that one is method and other is operator. One 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 .

The method compareTo() is used for comparing two strings lexicographically in Java.

It returns the following values:

  1. if (string1 > string2) it returns a positive value.
  2. if both the strings are equal lexicographically. i.e.(string1 == string2) it returns 0.
  3. if (string1 < string2) it returns a negative value.

What is == and equals in Java?

In simple words, == checks if both objects point to the same memory location whereas . equals() evaluates to the comparison of values in the objects. If a class does not override the equals method, then by default, it uses the equals(Object o) method of the closest parent class that has overridden this method.
