Hello, I am learning from TechVidvan Java Tutorial String myStr = sc.next() //reads string before the space It also throws IllegalStateException if the scanner is in a closed state.Ĭode to take String input using the next() method of Scanner class: package It does not accept any parameter and throws NoSuchElementException if no more tokens are available. Next method returns the next complete token from this scanner.
It retains the cursor in the same line after reading the input. It cannot read two words separated by space. Java next() method can read the input before space encounters. Using the next() method of Scanner class in Java In the above program, during the execution, the console waits after the line-Enter your name until the user enters something. ("Opted Course: " + course) Įnter the course that you want to learn from TechVidvan ("Enter the course that you want to learn from TechVidvan")
Now, let’s see the example to understand this concept:Ĭode to take String input using the nextLine() method of Scanner class: package Scanner scannerObject = new Scanner(System.in) So, the general syntax of taking String input using the Scanner class is: When this method does not find any String input on the console window, it throws NoSuchElementException and also throws IllegalStateException if we close the object of the Scanner class. The signature of the nextLine() method is: Then using the object of the Scanner class, we call the nextLine() method to read the String input from the user. The System.in represents the Standard input Stream that is ready and open to taking the input from the user. We create an object of the Scanner class and pass the predefined object System.in into it. The Scanner class is defined with the InputStream and system.in. To use this method we need to import the class in our code. The nextLine() method of the Scanner class takes the String input from the user. It comes with various methods to take different types of input from users like int, float, double, long, String, etc.
The Scanner class is a part of the java.util package in Java. Using Java Scanner class nextLine() method Using Command-line arguments of main() method 1. The following are some techniques that we can use to take the String input in Java:Ĥ. Let’s look forward to the various methods that take String input from the user. We can obtain as many as Strings inputs from the user as required. There are many utility classes and their methods that enable us to take the String input from the console. Taking string input in Java means taking the String input from the user through the keyboard and then the input values are processed and we get the desired output of the program.
