看到系统的一个错误，模拟一下：

**从下列实验可以看出是递归导致**

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();  
\}  
 \}  
\}

Exception in thread "main" java.lang.StackOverflowError
