See the example below: // importing BufferedReader class Let us now take an example, take String value as an input and print out that value. Now we already know the syntax of the BufferedReader class and creating the input from the user. Notice that we gave System.in as an argument which means this method is going to take input from the user.Įxample-1 Taking String value from the user using BufferedReader class See the syntax below: BufferedReader input = new BufferedReader(new InputStreamReader(System.in)) Let us now see the syntax of the Buffered class to take input from the user. So now, we have some idea of Buffered class. Syntax of Buffered class to take user input You will get a different name as output if you provide a different name as input.ĪLSO READ: If Else Java Statement Explained

The java code will not execute further until we provide the string/input. It is actually the input that we provide to our Scanner class. See the example below: // importing Scanner class Let us now take an example and see how we can get a string as an input from the user and then will print that string from the user. Now, we already know the syntax of the Scanner class and know some of the methods that are available in the Scanner class. It takes a long type of input value from the user.Įxample-1 Taking string as an input from the user It takes a short type input value from the user. It takes a double type input value from the user. It takes a byte type of input value from the user. It takes a word as an input value from the user. T takes a line as an input value from the user. It takes a boolean type input value from the user. It takes a float type input value from the user. It takes int type input value from the user.

It 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 like in competitive programming.ĪLSO READ: How to get sublist from a list in Java Methods The scanner class in java.util package used for obtaining the input of the primitive types like int, double, etc., and strings. The Scanner class is the most preferred method to take input from the user in the java programming language. Method-1: Java user input using Scanner class So, if you are not familiar with data types, you can learn from the article java data types. This tutorial requires basic knowledge of different data types that are available in java because we will be taking the input from users in different data formats. In this tutorial, we will cover all three methods but our focus will be on the scanner class and we will take various examples using scanner class. For example, using scanner class which is the most popular one, using Buffered class, and using the console. In the Java programming language, there are various ways to get input from the user. Moreover, we will cover various cases and examples of taking the input from the user. But our main focus will be the Scanner class because it is the most used and popular one. In this tutorial, we will learn about different methods that are available in java to take input from users including Scanner class, Buffered class, and console class. In java, we have three different kinds of methods through which we can take inputs from the user. In different programming languages, there are different methods to take input from the user. Sometimes, while writing code, we may want the user to input different values or we want to take the specified data type value from the user. Example of taking input from user using Java console class.Syntax of console class to take input from the user.Method-3: Java user input using console class.Example-2 Taking integer as an input using the BufferedReader class.Example-1 Taking String value from the user using BufferedReader class.Syntax of Buffered class to take user input.Method-2: Java user input using Buffered class.Example-3 Taking floating point as an input from the user.Example-2 Taking integer as an input from the user.Example-1 Taking string as an input from the user.Method-1: Java user input using Scanner class.
