Answer 1

2，读取程序java代码如下：
package test;import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;public class T { public static void main(String args[]){
T t=new T();
System.out.println(t.readFile2(new File("1.xml")));
}
    public static String readFile2(File f){
     // 建立可容纳1024个字符的数组 
        char data[]=new char[1024]; 
        StringBuffer temp = new StringBuffer();   
        // 建立对象fr 
        FileReader fr;
try {
fr = new FileReader(f.getCanonicalPath());
while (fr.read()>1){
        // 将数据读入字符列表data内 
        int num=fr.read(data); 
        // 将字符列表转换成字符串          
        String str=new String(data,0,num); 
        temp.append(str);
}
        // 输出在控制台 
        fr.close(); 
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} 
String temps=temp.toString();
        //System.out.println(temps); 
return temps;  
    }  
}

Answer 3

好像和文件本身的编码有关，我在eclipse开始是utf8的，不行，后来我换成gbk的就可以了

Answer 4

我的myeclipse默认就是gbk的啊！甚至测试的java类的编码方式都是gbk的。但是在控制台里面打印出来汉字就是乱码，为什么啊？
