PowerShell 6.x 及更早版本，包括 Windows PowerShell，不支持 && 和 ||，管道链操作符 - 它们仅在 PowerShell [Core] 7+ 中可用。
在 6.x 及更早版本中，您可以模拟 && 的行为如下：
javac Demo.java; if ($LASTEXITCODE -eq 0) { java Demo }
英文:
PowerShell versions 6.x and earlier, including Windows PowerShell, do not support && and ||, the pipeline chain operators - they're only available in PowerShell [Core] 7+
In 6.x and earlier, you can emulate the behavior of && as follows:
javac Demo.java; if ($LASTEXITCODE -eq 0) { java Demo }
