java里面输入输出流的一个乱码问题
我运行这个代码后，写入的文件里面全部是乱码，高手门，如何解决啊，谢谢
import java.io.*;
public class Main {
public static void main(String[] args) {
int ch ;
InputStreamReader iin = new InputStreamReader(System.in);
BufferedReader bin = new BufferedReader(iin);
File file1 = new File( "D:\\test\\111.txt ");
try
{
FileOutputStream fout = new FileOutputStream(file1);
DataOutputStream dout = new DataOutputStream(fout);
System.out.println( "输入整数 ");
int i = Integer.parseInt(bin.readLine());
System.out.println( "输入浮点数 ");
float f = Float.parseFloat(bin.readLine());
System.out.println( "输入布尔量 ");
boolean b = new Boolean(bin.readLine()).booleanValue();
dout.writeInt(i);
dout.writeFloat(f);
dout.writeBoolean(b);
dout.close();
}
catch (FileNotFoundException e)
{
System.out.println(e);
}
catch (IOException e)
{
System.out.println(e);
}
}
}
[解决办法]
乱码是正常的，不影响你写入的内容，这一点如果你把你写入的内容重新读回来的话，就知道了
[解决办法]
public static void main(String[] args) {
InputStreamReader iin = new InputStreamReader(System.in);
BufferedReader bin = new BufferedReader(iin);
File file1 = new File( "E:/111.txt ");
try {
FileWriter fw = new FileWriter(file1);
BufferedWriter bw = new BufferedWriter(fw);
System.out.println( "输入整数 ");
bw.write(bin.readLine());
bw.newLine();
System.out.println( "输入浮点数 ");
bw.write(bin.readLine());
bw.newLine();
System.out.println( "输入布尔量 ");
bw.write(bin.readLine());
bw.newLine();
bw.close();
fw.close();
bin.close();
iin.close();
} catch (FileNotFoundException e) {
System.out.println(e);
} catch (IOException e) {
System.out.println(e);
}
}
使用
FileWriter fw = new FileWriter(file1);
BufferedWriter bw = new BufferedWriter(fw);
