我正在尝试在 kotlin 中无限循环打印一个表，但得到了这个（线程“主”中的异常 java.lang.OutOfMemoryError: ZD52387880E1EA22817A72D375921389）

Question

need help to resolve this error Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

 Fun main(){
    Val num = 2
    Var i = 1
    while(i >= 1)
    {
    Println(num * i)
    }
    }

Answer 1

Well, it's fairly self-explanatory: you've run out of memory.

Answer 2

Value of i is always 1 and you are going in infinite loop so that's why out of memory is coming try to change the condition and you will get the output hope this helps

Fun main(){
    Val num = 2
    Var i = 1
    while(i >= 1)
    {
    Println(num * i)
    i=i-1
    }
    }

Answer 3

Calling println kicks off some internal operations that use memory, and if you spray a lot of them quickly enough, you can get an OOM (before garbage collection has a chance to run, I'm assuming)

exhibit A

fun main() {
    while (true) {
        println("uh oh")
    }
}
