- 使用递归演示，自己调用自己导致栈空间溢出，递归和回溯。
源代码:MyTest3.java
public class MyTest3 {
private int length;
public int getLength() {
return length;
}
public void test() {
this.length++;
test();
}
public static void main(String[] args) {
MyTest3 myTest3 = new MyTest3();
try {
myTest3.test();
} catch (Throwable throwable) {
System.out.println(myTest3.getLength());
throwable.printStackTrace();
}
}
}
通过设置VMOption:-Xss100k 设置堆栈的大小是512k(最小是160k)
运行结果:
5460
