5.9-2比较str1和str2截取后的子串 

 1 package zfc;

 3 public class ZfcShcq {
 4 
 5     public static void main(String[] args) {
 6         // TODO Auto-generated method stub
 7 
 8         String str1 = "Hello World !";//创建两个字符串
 9         String str2 = "Oracle Java";
10         
11         String s1 = str1.substring(7,9);//分别截取子串
12         String s2 = str2.substring(0,2);
13         
14 //        System.out.println(s1);//用于调试，查看子串
15 //        System.out.println(s2);
16         
17         if(s1.equalsIgnoreCase(s2))//比较子串，不区分大小写
18         {
19             System.out.println("两个子串相同");
20         }
21         else
22         {
23             System.out.println("两个子串并不相同");
24         }
25
