Scanner sc02 = new Scanner(inputStream input) Ħ. Scanner sc01 = new Scanner(File “myFile”) Ĥ. It can read input from a File, InputStream, and a String respectively. OR import java.util.* Creating a Scanner Class ObjectĪfter importing the package, the following lines of codes can be used to create an object of the Scanner class. Either of the following statements can be used to import the Java’s Scanner class and its functionality in your program. Like any other class, The package of the Scanner class is needed to be imported first to use the Java’s Scanner class. Although these functions are the easiest methods to read the input, these are often not the most efficient ones. Similarly, nextLine() and next() are used for string type and char type inputs. For instance, nextint() is used to take integer type input, and nextfloat() is for float type input. There are different functions in Java’s Scanner Class used to take input directly from the user or read from a file. The input is supposed to be of primitive data types, like int, float, double, string, etc. It is used to get input from the user during runtime.
Scanner Java class is part of the Java.util package. We will also learn about the various methods offered by the scanner class in Java with the aid of examples. In this article, you will discuss the input functionality of the Java language using the Java’s Scanner class. These functions are part of the Java Scanner class. The output on the screen is printed using () and () functions in Java. Java, being a programming language, also offers these functionalities that allow a Java program to take input and display the output to the user. A programming language would be of no use without these two functions. One of the most basic yet very important functionalities of any programming language is to successfully take input from the user and displaying the correct output.
