Java重定向输出

[quote]If you have too many errors in your program, then all the error messages fly by very quickly. The compiler sends the error messages to the standard error stream, so it's a bit tricky to capture them if they fill more than the window can display.[/quote]

如果遇到上面的问题，可以在执行的时候加上一个 [b]2>[/b]的参数

public class Text {
	public void exe(){
      String[] greeting = new String[3];
      greeting[0] = "Welcome to Core Java";
      greeting[1] = "by Cay Horstmann";
      greeting[2] = "and Gary Cornell";

      for(String g:greeting)
      System.out.println(g);
           }
	}

上面的例子，执行：
[quote]javac Text.java
java Text 2> error.out[/quote]

可以在文件夹里面得到一个 error.out的文件，里面是错误信息，这样就可以把错误信息重定向到了文件


如果JAVA没有错误，执行
[quote]javac Text.java
java Text > text.out[/quote]

可以把输出重定向到text.out文件里面
