vs code 配置java環(huán)境，并且利用powershell的特性完成了程序運行時間的計算，秒為單位，保留小數(shù)點后7為

輸入tasks：選擇configure task runner，將一下代碼貼到tasks.json
這樣就可以來運行java程序了，ctrl+F9
注意：
由于如果你想是javap 匯編出java程序，你可以
將如下
"$start=Get-Date;javac ${file} ; java ${fileBasenameNoExtension} ; $end=Get-Date; ('[Finished in ' + ($end - $start).TotalSeconds+ ' s]')"
換為：
"$start=Get-Date;javac ${file} ; javap -v ${fileBasenameNoExtension} ; $end=Get-Date; ('[Finished in ' + ($end - $start).TotalSeconds+ ' s]')"
{
