Comparing 2 Strings In Java

Objects is a utility class which contains a static equals method, useful in this scenario - to compare two Strings. The method returns true if two Strings are equal by first comparing them using their address i.e quotquot. Consequently, if both arguments are null, it returns true and if exactly one argument is null, it returns false.

However, we've used String constructor to create the strings. To compare these strings in Java, we need to use the equal method of the string. You should not use equality operator to compare these strings because they compare the reference of the string, i.e. whether they are the same object or not.

String compare by compareTo method. String compare by equals method. String compare by operator. String compare by compareTo method. The compareTo method compares two strings based on their lexicographical order, using the Unicode values of each character. It returns 0 if the strings are equal, a value less than 0 if the first string

Users can compare strings in Java using two ways, i.e., quotstring referencequot comparison and quotstring contentquot comparison.When comparing by reference, Java checks if the two strings are stored in the exact same memory location. On the other hand, content comparison checks if the characters in the strings are exactly the same.
