How to keep SDK and Java JRE installed and updated in a windows development environment

I do not know there is any other way of environment variables in a more practical way, I made a script in powershell to automate this process.

Limitations:

• Your environment variable must be named%

• Some java installs do not have the install location so they will not be displayed.

clear
write-host "Aguarde..."
[object[]]$r =  (Get-WmiObject win32_product -Filter " name like 'JAVA %'")

$javaHome = "JAVA_HOME"

Write-Host "Valor atual do JAVA_HOME: $env:JAVA_HOME 'n"

$opcao = 0
$itensValidos = @()
foreach($item in $r){
    if($item.InstallLocation -ne $null){
          Write-Host $opcao - $item.Name - $item.InstallLocation
          $itensValidos += $item
          $opcao++
    }
}

$selecionado = Read-Host "'nInforme qual instalação do java será definida em JAVA_HOME"


if($selecionado -lt 0 -or $selecionado -gt $itensValidos.Count -1){
   Write-Host "Opção invalida"
} 

[Environment]::SetEnvironmentVariable($javaHome, $itensValidos[$selecionado].InstallLocation +"lib" , 'Machine')
