一种可行的方法是使用startup script,例如 setLocale.jsh
,其中脚本的内容为:
java.util.Locale.setDefault(java.util.Locale.CANADA) // set your locale
然后您可以在jshell
命令行上使用
/set start <path to setLocale.jst>
并确保重置状态以应用更改
/reset
要验证Locale
中的更改,可以执行
java.util.Locale.getDefault() // prints en_CA
请注意,以上内容仅暗示jshell
的本届会议。可以使用-retain
选项保留设置,因此如果您使用
/set start -retain
然后,您下次调用jshell
工具时也会加载设置的启动脚本。
