Java数据流 基本字符流

基本字符流

 

public String readLine()   //从输入流读取一行字符，BufferedReader的方法

public void newLine()   //从输出流写入一行结束的标志，BufferedWriter的方法

 

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStreamReader;

public class FileToUnicode {
    public static void main(String args[]){
        try{
            FileInputStream fis = new FileInputStream("file1.txt");
            InputStreamReader dis = new InputStreamReader(fis);
            BufferedReader reader = new BufferedReader(dis);
            String s;
            while ((s = reader.readLine())!= null){
                System.out.println("read:"+s);
            }
            dis.close();
        }catch(IOException e){
            System.out.println(e);
        }
        
    }//main()
}//class

 

实现将字符串从标准输入通道读取字符串信息然后将其输出

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class CharInput {
    public static void main(String args[]) throws IOException {
        String s;
        InputStreamReader ir = new InputStreamReader(System.in);
        BufferedReader in = new BufferedReader(ir);
            while ((s = in.readLine())!= null){
            System.out.println("Read:"+ s );
        }
    }

}
