JAVA 基础例题包含了JAVA常见的问题和常见的习题

import java.io.*;
public class Input1
{
    public static void main(String args[]) throws IOException
    {  
        System.out.println("Input: ");
        byte buffer[] = new byte[512];         //输入缓冲区
        int count = System.in.read(buffer);    //读取标准输入流
        System.out.println("Output: ");
        for (int i=0;i<count;i++)              //输出buffer元素值
        {
            System.out.print(" "+buffer[i]);
        }
        System.out.println();
        for (int i=0;i<count;i++)              //按字符方式输出buffer
        {
            System.out.print((char) buffer[i]);
        }
        System.out.println("count = "+ count); //buffer实际长度
    }
