Difference between matches and equalsIgnoreCase or equals in string class

Question

matches: Will check if the complete string entered is equal to the value present in the string object.

equalsIgnoreCase: Ignoring t

Answer 1

There is a big difference - matches checks the match of a String to a regular expression pattern, not the same string. Do not be mislead by the fact that it receives a String as an argument.

For example:

"hello".equals(".*e.*"); // false
"hello".matches(".*e.*"); // true
