编写一个使用string类的compareTo方法来比较用户所输入的两个字符串应用程序。输出1个字符串是小于、等于还是大于第二个字符串。用图形用户界面输入输出。

import java.io.BufferedReader; 
import java.io.IOException; 
import java.io.InputStreamReader; 
public class StrTest { 

public static void main(String[] args) { 
String inputStr1 = null,inputStr2 = null; 
int result; 
BufferedReader br =new BufferedReader(new InputStreamReader(System.in)); 
BufferedReader br1 =new BufferedReader(new InputStreamReader(System.in)); 
try { 
System.out.print("Please Input the first string:"); 
inputStr1=br.readLine(); 
System.out.print("Please Input the second string:"); 
inputStr2=br1.readLine(); 
} catch (IOException e) { 
e.printStackTrace(); 
} 
result=inputStr1.compareTo(inputStr2); 
if(result==0) 
System.out.println(inputStr1+"=="+inputStr2); 
else 
{ 
if(result<0) 
System.out.println(inputStr1+"<"+inputStr2); 
else 
System.out.println(inputStr1+">"+inputStr2); 
} 
} 
}
