從下列實驗可以看出是遞迴導致

import java.util.ArrayList;
import java.util.List;
public class InfiniteRecursion {
 public static void main(String[] args) {
InfiniteRecursion  oo = new InfiniteRecursion();
oo.getString();
 }
 private static void getString(){
 for (int i = 0; i < 1000000; i ++){
 getString();
}
 }
}
