程序使用FileWriter创建文本文件。
import java.io.FileWriter;
import java.io.IOException;
class Wx {
public static void main(String args[]) throws IOException {
String str = "Oh ho ho ho oh ho ho ho oh ho ho ho ohho ishq tera tadpaaweee ";
FileWriter f = new FileWriter("text");
for (int i = 0; i < str.length(); i++) {
f.write(str.charAt(i));
f.close();
}
}
}
该异常即将到来:
Exception in thread "main" java.io.IOException: Stream closed
at sun.nio.cs.StreamEncoder.ensureOpen(StreamEncoder.java:26)
at sun.nio.cs.StreamEncoder.write(StreamEncoder.java:99)
at sun.nio.cs.StreamEncoder.write(StreamEncoder.java:94)
at java.io.OutputStreamWriter.write(OutputStreamWriter.java:177)
at Wx.main(Wx.java:10)
此异常反复出现,经过大量努力无法将其删除。
最佳答案
您继续关闭for循环中的流。像这样将其移到大括号之外:
import java.io.*;
class Wx {
public static void main(String args[]) throws IOException {
String str="Oh ho ho ho oh ho ho ho oh ho ho ho ohho ishq tera tadpaaweee";
FileWriter f=new FileWriter("text");
for(int i=0;i<str.length();i++) {
f.write(str.charAt(i));
}
f.close();
}
}
