@Java Guides How to do autowiring based on condition. Let say here in below code if there is one variable choice if choice =1 then I want Samsung class injected if choice =2 then Redmi if choice =3 then Apple.

. class AppService
{
@Autowire
Mobile mobile;
}

class Samsung implements Mobile{

getProperties()
{
println("Memory: 500GB", "RAM :32GB", "color": Golden)
}
}

class Redmi implements Mobile{

getProperties()
{
println("Memory: 250GB", "RAM" :32GB", "color": Orange)
}
}

class Apple implements Mobile{

getProperties()
{
println("Memory: 1TB", "RAM" :32GB", "color": pink)
}
}
