The equals() method compares two strings, and returns true if the strings are equal, and false if not. Tip: Use the compareTo() method to compare two strings lexicographically.
a.equals(b) checks if two objects are equals based on equals() implementation. a==b checks if two objects have same reference. If a==b is true then a.equals(b) must be true because they are referencing to the same object but not vice-versa.
Both the equals () method and the == operator are used to compare two objects in Java. The Java string equals () method, compares two strings and returns true if all characters match in both strings, else returns false.

If two object's hashcode are equals that doesn't means two objects are equal. For two objects, if equals method returns true then hashcode must be same. You will have to override equals method to decide on which basis you want object e1 and e2 in above code is equal.
Learn to compare Java strings using equals () method, equalsIgnoreCase () method and == operator.
The equals() method returns true if two strings are identical and false if the strings are different. public static void main(String[] args) { String str1 = "Learn Java"; String str2 = "Learn Java"; // comparing str1 with str2. System.out.println(result); // Output: true. The syntax of the String equals() method is:
The String.equals() method in Java is a fundamental tool for comparing strings for content equality. By understanding how to use this method, you can accurately check if two strings are the same, considering case sensitivity and handling potential null values.
