程序如下，不知道为啥输出后txt文档里面是乱码。求助，怎么修改都还是一样……

import import import public class OutPutData {

    public static void main(String[] args) throws Exception{
        File f=new File("E:" + File.separator+"data.txt");
        DataOutputStream put = new DataOutputStream(new FileOutputStream(f));
        int no[]={2014001,2014002,2014003};
        String  name[]={"张三","张五","丽丽"};
        float PE[]={75.5f,85f,98f};
        float Math[]={85.5f,75.5f,78f};
        for(int i=0;i<name.length;i++){
            put.writeInt(no[i]);
            put.writeChar('\t');
            put.writeChars(name[i]);
            put.writeChar('\t');
            put.writeFloat(Math[i]);
            put.writeChar('\t');
            put.writeFloat(PE[i]);
            put.writeChar('\n');
        }
        put.close();
        System.out.println("输出完成。");
    }

}

File f=new File("E:" + File.separator+"data.txt");
//        DataOutputStream put = new DataOutputStream(new FileOutputStream(f));
        
        PrintWriter put=new PrintWriter(new FileOutputStream(f));
        
        int no[]={2014001,2014002,2014003};
        String  name[]={"张三","张五","丽丽"};
        float PE[]={75.5f,85f,98f};
        float Math[]={85.5f,75.5f,78f};
        for(int i=0;i<name.length;i++){
            put.print(no[i]);
            put.print(name[i]);
            put.print(PE[i]);
            put.print(Math[i]);
            put.println();
//            put.writeInt(no[i]);
//            put.writeChar('\t');
//            put.writeChars(name[i]);
//            put.writeChar('\t');
//            put.writeFloat(Math[i]);
//            put.writeChar('\t');
//            put.writeFloat(PE[i]);
//            put.writeChar('\n');
        }
        put.close();
        System.out.println("输出完成。");

上面是我改写的，也可以用了写入.txt文本；DataOutputStream用这个函数去写应该是会出现乱码，但它还有一个读取的是专门来读取它写入的，所以我个人总结就是你用DataOutputStream去写入就要用DataInputStream去读取
