在Mac OS X上开始使用Java开箱即用

Question

我在MacBook上安装10.5.3似乎不想从Sun 构建示例.它声称它无法找到要导入的java.io.Console.这对我来说很烦人,经过多次搜索后我无法弄清楚我应该怎么做才能修复它.

我已经安装了Apple Developer Tools.

这是发生的事情:

macbook:~ dlamblin$ javac RegexTestHarness.java
RegexTestHarness.java:32: cannot find symbol
symbol  : class Console
location: package java.io
import java.io.Console;
               ^
RegexTestHarness.java:39: cannot find symbol
symbol  : class Console
location: class RegexTestHarness
        Console console = System.console();
        ^
RegexTestHarness.java:39: cannot find symbol
symbol  : method console()
location: class java.lang.System
        Console console = System.console();
                                ^
3 errors

mmyers已经暗示过这一点,但听起来你还没有升级到Java 6.你可以从这里得到它:http://support.apple.com/downloads/Java_for_Mac_OS_X_10_5_Update_4
