class CompareString 
{
	public static void main(String[] args) 
	{
	String str = "this is a test";
	//不相同，r1为负值
	int r1 = str.compareTo("this is a test and more");
	//不相同，r2为负值，原因是'n'<'a'
	int r2 = str.compareTo("this is not a test");
	//相同，r3为零
	int r3 = str.compareTo("this is a test");
	//不相同，r4为正值，原因是't' > 'n'
	int r4 = str.compareTo("no, this is not a test");
	//不相同，r5为正值，原因是str长度小
	int r5 = str.compareTo("this");
	//类型转换错误
	//int r6 = str.compareTo(new Integer(10));
	}
