Read line of chars from console with InputStream

In this example we shall show you how to read a line of chars from console with an InputStream. This abstract class is the superclass of all classes representing an input stream of bytes. Applications that need to define a subclass of InputStream must always provide a method that returns the next byte of input. To read a line of chars from console with an InputStream one should perform the following steps:

  • Use System.in to get the standard InputStream.
  • Create a new BufferedReader with a new InputStreamReader with the specified InputStream.
  • Use readLine() API method of BufferedReader to read a line of text.
  • Close the BufferedReader, using the close() API method,

as described in the code snippet below.

package com.javacodegeeks.snippets.core;

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

public class ReadLineOfCharsFromConsoleWithInputStream {
	public static void main(String[] args) {
		InputStream is = null;
		BufferedReader br = null;
		try {
			is = System.in;
			br = new BufferedReader(new InputStreamReader(is));
			String line = null;
			while ((line = br.readLine()) != null) {
				if (line.equalsIgnoreCase("quit")) {
				System.out.println("Line entered : " + line);
		catch (IOException ioe) {
			System.out.println("Exception while reading input " + ioe);
		finally {
			// close the streams using close method
			try {
				if (br != null) {
			catch (IOException ioe) {
				System.out.println("Error while closing stream: " + ioe);
