    }

}

我需要输出应该与此框中提供的ping命令完全相同而不是它给出了输出？例如命令窗口上的ping输出以 Pingwirdusgeführtfür10.11.11.67mit 32 Bytes Daten：

但是当我从代码中运行时我得到了

Ping wird ausgef？hrt f？r 10.11.11.67 mit 32 Bytes Daten：

检查für和f？r

可能是导致此问题的jvm编码。尝试在环境变量中设置（计算机 - >属性 - >高级系统设置 - >新变量）

变量名称：JAVA_TOOL_OPTIONS
变量值：-Dfile.encoding = UTF8

附加的Java代码不能在Windows 2008 R2德语语言环境中正确输出德语字符
