Equals as "=": This is an assignment operator in java which is used in an expression to assign a value to a variable.

Equals as function: This is a function in the java.lang.*; package in java to check whether two strings(words) are equal(identical) or not.

If the cases of two words are unequal then it returns false.

e.g.-

String a="cat",b="Cat";

a.equals(b);

The value returned would be false.

a.equalsIgnoreCase(b);

The value returned would be true.

The above function is also in the lang package.
