How to define a string in Java?

In Java, you can define strings using the String class. Strings can be defined in two ways.

1. Define a string using literal values: You can simply enclose the content of the string in double quotes and assign it to a variable, for example:

String str = "Hello World";

1. Rope

String str = new String("Hello World");

It is important to note that strings are immutable, meaning once a string object is created, its contents cannot be changed. If modifications are required, certain methods in the String class can be used, such as concat() for string concatenation, and substring() for extracting substrings.
