Answer 1

A stack trace is an array of StackTraceElement. Why wouldn't it have a length?

Outside of Java, all stacks of anything have a height. Consider a stack of books. Height is to stack as length is to array.

Maybe you're overlooking that the stack contains something other than its length. Every element in the stack represents a method call. If method1 calls method2... and method10, the stack is an array of all those method calls and the length is how many calls happen.

Method 1 returns 12 because the call stack it leads to is
[
main, method1, method2, method3, method4, method5, method6, method7, method8, method9, method10, java.lang.Thread.getStackTrace
] and there are 12 elements in that array.
