A JVM application starts by reserving memory, and the smallest hosting plans do not have enough of it. That, more than language support, is what decides whether Java is practical somewhere: a provider may list it and offer no plan with the headroom for a Spring Boot service under load. Deployment is usually a jar or a container. Where Java appears alongside enterprise support tiers, the pricing usually reflects the audience rather than the runtime.
20 providers run Java, listed alphabetically. Mostly Platform as a Service, shared hosting and serverless, of 9 categories in all. 45 records do not record this field, and cannot appear here either way.
