如何将Java编译器错误捕获到文件中? [英] How can I capture Java compiler errors into a file?

问题描述

我将Java程序编译为

I compiled a Java program as

javac t1.java > a

，以便将错误消息重定向到文件a.但是a没有错误内容(它们仍然出现在终端中).该命令从Linux命令提示符处执行.

in order to redirect the error messages to file a. But a doesn't have the error contents (they still appear in the terminal). The command is executed from Linux command prompt.

t1.java的内容为:

The contents of t1.java is as:

class t1 {
    public static void main(String[] args) {
       System.out.printn("Hello World!"); // Display the string.
    }
}

所以现在有一个错误，即println被写为printn.

So now there is an error, i.e. println is written as printn.

如何在文件a中捕获此错误消息?

How can I capture this error message in file a?

推荐答案

尝试重定向stderr:

javac t1.java 2> error_file
