Which import statement should be included in the source code of a classso that the Math class is explicitly imported? Choose from the givenchoices. * An application that is created using the Java programming language may be a collection of classes andeach class has methods and data members. Some of the classes involved in an application are predefinedand their methods are designed to perform a specific task. The predefined classes are organized intocollections of classes known as class libraries or packages. Three commonly used predefined classes arethe Math class, the Character class, and the String class. The Math class contains predefined methodsfor performing mathematical operations. For example, sqrt is a method in the predefined Math class andit (the sqrt method) is used to calculate the square root of a number. The Character class containspredefined methods for character manipulation. For example, the toLowerCase method in the predefinedCharacter class is used to change a given character value to lowercase if the character value is a capitalletter. The String class contains predefined methods for manipulating strings. To use the methods of apredefined class, the library or package that contains the predefined class must be imported by an importstatement.

Question

Which import statement should be included in the source code of a class
so that the Math class is explicitly imported? Choose from the given
choices. *

An application that is created using the Java programming language may be a collection of classes and
each class has methods and data members. Some of the classes involved in an application are predefined
and their methods are designed to perform a specific task. The predefined classes are organized into
collections of classes known as class libraries or packages. Three commonly used predefined classes are
the Math class, the Character class, and the String class. The Math class contains predefined methods
for performing mathematical operations. For example, sqrt is a method in the predefined Math class and
it (the sqrt method) is used to calculate the square root of a number. The Character class contains
predefined methods for character manipulation. For example, the toLowerCase method in the predefined
Character class is used to change a given character value to lowercase if the character value is a capital
letter. The String class contains predefined methods for manipulating strings. To use the methods of a
predefined class, the library or package that contains the predefined class must be imported by an import
statement.
