Read char from console with InputStream

This is an example of how to read a char from console using an InputStream. It is an abstract class that 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. Reading a char implies that you should:

  • Use System.in to get the standard InputStream.
  • Use read() API method of InputStream to read the next byte of data from the input stream. You can cast it to a char variable.

Let’s take a look at the code snippet that follows:

package com.javacodegeeks.snippets.core;

import java.io.IOException;
import java.io.InputStream;

public class ReadCharFromConsoleWithInputStream {
	public static void main(String[] args) {
		try {
			InputStream is = System.in;
			// Reads the next byte of data from the input stream
			char c = (char) is.read();
		catch (IOException ioe) {
			System.out.println("Exception while reading input " + ioe);

This was an example of how to read a char from console using an InputStream in Java.
