![]() This means that the variable p stores a float type value through the scanner object ‘sc’. It receives floating type value and stores it into a floating type variable. This means that the variable p stores an integer through the scanner object ‘sc’. It is stored in an integer type variable. It receives an integer from the scanner object. Methods to read data from the scanner object nextInt() It has an easier approach to read records from a data file. String manipulation is easier as each word can be obtained as a token and handled separately.ĥ. The program logic is simple because the scanner class has various methods to manipulate input data.Ĥ. ![]() InputStreamReader and BufferReader are not required to be mentioned.ģ. The user doesn’t need to mention the set of data being input from the console.Ģ. Advantages of input through scanner classġ. The parameter ‘System.in’ allows the constructor to receive data from the keyboard. The scanner class has a constructor which is automatically invoked to store values in the scanner object from the console.Ĥ. The new keyword can be used for dynamic allocation of the scanner object.ģ. ‘sc’ is an object of type Scanner (you can use any object name of your choice)Ģ. The process of importing is shown below:Īfter importing the java.util package, you can use the scanner class and creating an object which can hold a set of values of different types.ġ. You must import java.util package to be able to use all the facilities of the scanner class. However, the output statement remains the same i.e., () or (). This class is helpful in inputting different types of numeric and non-numeric data. In order to use scanner class in java programming, you need to install atleast jdk 1.5 or above versions of jdk. The end of values can be determined by a sentinel character or string. It does not require the limit of values to be mentioned in advance by the users. There are many methods in the scanner class that we need to take input for various data types. The scanner class is defined within a package named java.util. The Scanner Class in java allows user to input the values of various data types. ![]() ![]() Methods to read data from the scanner object.Advantages of input through scanner class. ![]()
