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();
System.out.println(c);
}
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.
