StackOverflowError异常

最简单的：

public class TestStackOverflowError {
	
               TestStackOverflowError ts = new TestStackOverflowError();
	
                public static void main(String[] args) {
		TestStackOverflowError ts = new TestStackOverflowError();

	}

}

 无意识造成的（tij11)：

public class InfinitRecursion {

	public String toString(){
		return "InfinitRecursion address:" +this +"\n";
		//return "InfinitRecursion address:" +super.toString() +"\n";
	}
	public static void main(String[] args) {
		InfinitRecursion ir = new InfinitRecursion();
		System.out.println(ir);

	}

}

自动忽略（java puzzle 49?)

public class Reluctant {

	private  Reluctant internalInstance = new Reluctant();
	
	public Reluctant(){
		
	}
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Reluctant rel = new Reluctant();
	}

}

  

一道笔试题：

public class Device {
	private View v = new View();
	public void hehe(){
		v.notice();
	}

}
public class Moter extends Device {
	
	public int getState(){

	}
	public void haha(){
		hehe();
	}

}
public class View {
	private Moter m ;
	public void notice(){
		m.getState();
	}

}

public class B extends A{
A a = new A();// 自然不会出现异常
