Java user input. the scanner class is used to get user input, and it is found in the java.util package. to use the scanner class, create an object of the class and use any of the available methods found in the scanner class documentation. in our example, we will use the nextline() method, which is used to read strings:.

Java Programming Tutorial 6 Getting User Input Using Main Method Output: enter an integer: 23. you entered 23. in the above example, we have created an object named input of the scanner class. we then call the nextint() method of the scanner class to get an integer input from the user. similarly, we can use nextlong(), nextfloat(), nextdouble(), and next() methods to get long, float, double, and string input. The scanner class of the java.util package is used to read input data from different sources like input streams, users, files, etc. in this tutorial, we will learn about the java scanner and its methods with the help of examples. You can get the user input using scanner. you can use the proper input validation using proper methods for different data types like next() for string or nextint() for integer. import java.util.scanner; scanner scanner = new scanner(system.in); reads the input until it reaches the space. Here is the syntax for the java scanner class: scanner input = new scanner (system.in); int number = input.nextint(); in this example, we created a variable called input that collects the next value the user inputs into the console. then we created a variable called number that collects the value the user submits to the console.

Last updated : 13 dec, 2023. in java, scanner is a class in java.util package used for obtaining the input of the primitive types like int, double, etc. and strings. using the scanner class in java is the easiest way to read input in a java program, though not very efficient if you want an input method for scenarios where time is a constraint. In this tutorial we are gonna see how to accept input from user. we are using scanner class to get the input. in the below example we are getting input string, integer and a float number. for this we are using following methods: 1) public string nextline (): for getting input string. 2) public int nextint (): for integer input.
