从console读取数据的简单方法
package io;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.util.Scanner;public class ConsoleInput {public static void main(String[] args) {ConsoleInput consoleInput = new ConsoleInput();consoleInput.viaScanner();consoleInput.viaBufferedReader();}/** * 通过java.util.Scanner类来读取 */void viaScanner(){Scanner in = new Scanner(System.in);System.out.println("得到第一个输入:"+in.nextLine());//如果输入的不是数字会报java.util.InputMismatchExceptionSystem.out.println("得到第二个输入:"+in.nextFloat());}/** * 通过BufferedReader来读取 */void viaBufferedReader(){BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));try {System.out.println("得到第三个输入:"+reader.readLine());} catch (IOException e) {e.printStackTrace();}}}?
