A Java class called Scanner is used to get input of primitive types like int, double, etc. and strings. Although it is the simplest technique for reading input in a Java application, it is not particularly effective if you need an input method for situations where speed is a factor, such as in competitive programming.
Here is how to construct Scanner objects when we import the package. / Take a reading from the input stream Scanner sc2 = new Scanner(File file); / read input from a string Scanner sc1 = new Scanner(InputStream input); / read input from files new Scanner(String str); Scanner sc3; use-case package you must either include a Java Scanner import line at the beginning of your class or when you call the Scanner. A Java Scanner import is advised to keep your code legible and concise. util. both the classes an applet needs to interact with its applet environment and the classes required to construct an applet are provided. Contains every class for designing user interfaces and for drawing and painting visuals.
