如您所知,我们在java中有几个用于将数据写入流的工具.
在此示例代码中,我按运行时对它们进行了比较.
有人可以解释一下吗？谢谢.
这是代码:

import java.io.FileOutputStream;
import java.io.OutputStreamWriter;
import java.io.PrintStream;
import java.io.PrintWriter;

public class IOtests
{

public static void main(String[] args) throws Exception
{
    char[] chars = new char[100];
    byte[] bytes = new byte[100];
    for (int i = 0; i < 100; i++)
    {
        chars[i] = (char) i;
        bytes[i] = (byte) i;
    }
    OutputStreamWriter out = new OutputStreamWriter(new FileOutputStream(
            "output.txt"));
    long a = System.currentTimeMillis();
    for (int i = 0; i < 100000; i++)
        for (char j : chars)
            out.write(j);
    System.out.println("OutputStreamWriter …

这让我很生气(Eclipse Kepler)

public class FastReader 
{
public static void main (String[] args)
{
    FastReader a = new FastReader("hi");
}
public FastReader(int a)
{

}
public FastReader(String b)
{
    FastReader(10);
}
}

我收到这个错误:

Exception in thread "main" java.lang.Error: Unresolved compilation problem: 
The method FastReader(int) is undefined for the type FastReader    
at FastReader.<init>(FastReader.java:14)
at FastReader.main(FastReader.java:6)

这几乎让我发疯了!帮我摆脱这个!谢谢!
