帮我看看

[pkvov]

import java.io.*;

public class Copy {
public static void main(String[] args) throws IOException {
File inputFile = new File("farrago.txt");
File outputFile = new File("outagain.txt");

FileReader in = new FileReader(inputFile);
FileWriter out = new FileWriter(outputFile);
int c;

while ((c = in.read()) != -1)
out.write(c);

in.close();
out.close();
}
}

我用sdk+ultraedit
javac Copy.java 通过后生成Copy.class
java Copy.class 出现 Exception in thread "main"java.lang.NoClassDefFoundError:Copy/class
百思不得其解！

请检查classpath

java Copy
同意

[learnner]

java Copy.class 改成 java Copy 来运行，如果classpath配置正确就应该可以了
