Java中比较两个字符串

Java中比较两个字符串
方法：通过字符串函数ocmpareTo(String),compareTolgnoreCase(String)及compareTo(object string)来比较两个字符串，并返回字符串中的第一个字母ASC11的差值

public class StringCompareEmp {
	public static void main (String[] args){
		String str = "Hello world";
		String anotherString = "hello world";
		Object object = str;
		System.out.println(str);
		System.out.println(anotherString);
		System.out.println(str.compareTo(anotherString));
		System.out.println(str.compareToIgnoreCase(anotherString));
		System.out.println(str.compareTo(object.toString()));
	}
}

结果：
