** 1.目标：输出b.txt下的记事本字符**

**2.代码：**

package IOChar;
    
    import java.io.File;
    import java.io.FileNotFoundException;
    import java.io.FileReader;
    import java.io.IOException;
    import java.io.Reader;
    
    /**
     * 纯文本读取
     * @author john
     *
     */
    public class Demo1 {
    	public static void main(String[] args){
    		//创建源
    		File src=new File("G:/iotest/IOChar/b.txt");
    		//选择流
    		Reader reader=null;
    		try {
    			reader=new FileReader(src);
    			//读取操作
    			char[] flush=new char[10];
    			int len=0;
    			try {
    				while(-1!=(len=reader.read(flush))){
    					//字符数组转字符串
    					String str=new String(flush,0,len);
    					System.out.println(str);
    				}
    			} catch (IOException e) {
    				e.printStackTrace();
    				System.out.println("文件不存在");
    			}
    		} catch (FileNotFoundException e) {
    			e.printStackTrace();
    			System.out.println("源文件不存在");
    		}finally{
    			if(null!=reader){
    				try {
    					reader.close();
    				} catch (IOException e) {
    					e.printStackTrace();
    				}
    				
    			}
    		}
    	}
    
    }

**3.结果**
