how much memory a thread takes in java [closed]

Answer 1

The amount of memory allocated for a thread stack is specific to your JVM Version + Operating System. It is configured with the -XX:ThreadStackSize option (-Xss on older versions.) Anecdotally 512KB is "normal", although it is 1024 on 64-bit linux which is probably the platform it's most commonly critical (one guy's opinion anyway)

Answer 2

Each thread in a Java application has its own stack. The stack is used to hold return addresses, function/method call arguments, etc And by default stack size is 512KB. You can change by -Xss jvm command.
