Question

java中怎么判断一个字符串的前缀和后缀是否与另一个字符串相同？

Answer 1

String str1 = "abcasdfasdfabc";
String str2 = "abcdsdfasdfasdfasdfasdabc";
if(str1.startsWith(str2.substring(0,2))&&str1.endsWith(str2.substring(str2.length()-3)))
System.out.println("两个字符串前三位和后三位都相同");
else
System.out.println("两个字符串前三位和后三位不相同");

Answer 2

一、

1、String str1 = "abcasdfasdfabc";

String str2 = "abcdsdfasdfasdfasdfasdabc";

if(str1.startsWith(str2.substring(0,2))&&str1.endsWith(str2.substring(str2.length()-3)))

System.out.println("两个字符串前三位和后三位都相同");

else

2、   System.out.println("两个字符串前三位和后三位不相同");

二、写一个Java应用程序，判断两个字符串是否相同，判断字符串的前缀、后缀是否和某个字符串相同，按字典顺序比较两个字符串的大小关系，检索字符串，创建字符串，将数字型字符串转换为数字，将字符串存放到数组中。

用字符数组创建字符串-Write a Java application to determine whether two strings are the same judgment string prefix, suffix and a string compare two strings lexicographically size relationship, retrieve the strings to create a string, converted to a digital numeric string, the string stored in the array, create a string array of characters.
