Simple input from the keyboardTag(s): IO
First method
import java.io.*; public class TestReadLine { public static void main (String args[]) { StreamTokenizer Input=new StreamTokenizer(System.in); try { System.out.print(" Your first name : "); Input.nextToken(); System.out.println("Hi " + Input.sval + "!"); } catch (Exception e) { e.printStackTrace(); } } }
java.io.DataInputStream in = new java.io.DataInputStream(System.in); String aLine = in.readLine();
Third method JDK1.1
In you program, use EasyInput.inputStr("<prompt>") to input a String or
EasyInput.InputInt("<prompt>") for an integer.
public class EasyInput { public static int inputInt(String s) { BufferedReader input = new BufferedReader(new InputStreamReader(System.in)); System.out.print(s); int i =0; try { i = Integer.parseInt(input.readLine()); } catch (Exception e) { e.printStackTrace(); } return i; } public static String inputStr(String s) { String aLine = ""; BufferedReader input = new BufferedReader(new InputStreamReader(System.in)); System.out.print(s); try { aLine = input.readLine(); } catch (Exception e) { e.printStackTrace(); } return aLine; } public static void main(String s[]) { while(true) { int y = inputInt(" Year: "); int m = inputInt("Month: "); int d = inputInt(" Day: "); String you = inputStr("Your name: "); System.out.println(you + " " + y + m + d); } } }
NOTE: JDK 1.5 provides the Scanner class to do this, see this HowTo.
