In Java, you can import a class or package from another library or project using the import statement. To import the String class, which is a built-in class in the Java Standard Library, you can use the following import statement:
import java.lang.String;
This will allow you to use the String class in your code without having to specify the fully qualified name of the class (i.e., java.lang.String) every time you use it.
It's important to note that the import statement is not necessary if you are using the fully qualified name of the class. For example, you could use the String class without importing it like this:
java.lang.String str = "hello";
However, using the import statement can make your code easier to read and maintain, as you don't have to specify the fully qualified name of the class every time you use it.
If you are using an IDE like Eclipse or IntelliJ, you can usually use code completion to automatically import the necessary classes and packages for you.
