Reading Console Input in Java
|
Reading console input in simple java console applications is a very straight forward process. Java provides developers two predefined streams in the java.lang.System class to read and write data to and from standard input and output devices. System.out is a standard output stream which is Console by default and System.in is predefined input stream which is Keyboard by default. To read user input in a console window we connect system.in with other stream classes available in java.io package.

{
public static void main(String[] args) throws Exception
{
System.out.println("Enter Your Text: " );
InputStreamReader r = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(r);
String s = br.readLine();
System.out.println(s);
}
}
