SHARE & COMMENT :

This simple example shows how to get the standard input from console in Java. When you run this program, it asks the user for the input, if you enter a value, it is printed in the console. Let’s try this example.

StdInputExample.java

package javabeat.net.core;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class StdInputExample {
	public static void main(String args[]) {
		try {
			//BufferedReader with InputStreamReader
			BufferedReader bufferReader = new BufferedReader(new InputStreamReader(
					System.in));
			String inputValue;

			//Reads and prints it
			while ((inputValue = bufferReader.readLine()) != null) {
				System.out.println("You entered : "+inputValue);
			}
		} catch (IOException io) {
			io.printStackTrace();
		}
	}

}
