Re: Java - Reading from console Take a look at this example. This may help you Code: public class InputHandler{ public static void main(String[] args) { System.out.println("Reading from console."); double numberFromConsole; try { InputStreamReader isr = new InputStreamReader(System.in); BufferedReader br = new BufferedReader(isr); String s = br.readLine(); DecimalFormat df = new DecimalFormat(); Number n = df.parse(s); numberFromConsole = n.doubleValue(); } catch (IOException e) { numberFromConsole = 0; } catch (ParseException e) { numberFromConsole = 0; } System.out.println(numberFromConsole ); } } |

Re: Java - Reading from console The above example is good, but you can have a glance at this example. Code: public class Echo { public static void main(String args[]) throws Exception{ BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); String input = ""; while(true){ System.out.print("ECHO< "); input = in.readLine(); if ("".equals(input)){ break; }else if ("ok".equals(input)){ System.out.println("OK command received: do something �"); System.out.println("ECHO> " + input.toUpperCase()); } } } |

Re: Java - Reading from console Take a look at this example. Reading from the console is done in a different way Code: import java.util.Scanner; public class InputExp { public static void main(String[] args) { String nm1; int ag; Scanner in = new Scanner(System.in); // Reads a single line from the console // and stores into nm1 variable nm1 = in.nextLine(); // Reads a integer from the console // and stores into ag variable ag=in.nextInt(); in.close(); // Prints nm1 and ag to the console System.out.println("Name :"+nm1); System.out.println("Age :"+ag); } }
