public class Test { // line n1 } Which two code fragments can be inserted at line n1? String str = "Java"; package pl; for(int iVal = 0; iVal <= 5; iVal++) {} import .*; Test() {}

In the context of Java programming and using the provided code snippet, you are looking to determine which code fragments can be inserted at line n1 in the class declaration of a public class 'Test'. The key is to find elements that are appropriate for declaration and placement within a Java class.
Here are two code fragments that can be inserted at line n1:

String str = "Java";

This line is perfectly valid within a class since it declares a member variable. In Java, you can define a field inside a class body. The variable 'str' is of type 'String', and it is initialized to "Java". This kind of declaration is commonly used to keep track of important information or to share data across methods within the class.


Test() {}

This line represents a constructor for the class 'Test'. Constructors in Java are special methods that are called when an object of the class is created. A constructor typically has the same name as the class and no return type. In this case, 'Test() {}' defines a default constructor with no parameters and no executable code (an empty body), which is appropriate and allowed within a Java class. Even though it's empty, it serves to initialize new objects of the 'Test' class and can be expanded for custom initialization logic.



Inserting these code fragments at line n1 would enhance the functionality of the class without any syntax errors, making it a complete and functional Java program. Both fragments are valid as they comply with standard Java class structure conventions.
