字符串之替换字符串中连续出现的指定字符串

题目：

字符串之替换字符串中连续出现的指定字符串

给定3个字符串str from to已知from字符串无重复字符，把str中所有from的子串全都替换成to字符串，连续出现from只需要换成一个to就可。

例如：

str="123" from = "adc" to ="4567" 返回123

str="123adcabc" from = "adc" to ="X" 返回123X

实现代码：

  

   

    

     

    
    

     

      package com.chenyu.string.cn;
     
    
   

    

     

    
    

     
 
     
    
   

    

     

    
    

     

      public class RaplaceString {
     
    
   

    

     

    
    

     
	
     
    
   

    

     

    
    

     

      	public static void main(String[] args) {
     
    
   

    

     

    
    

     
		
     
    
   

    

     

    
    

     

      		String target = "000abcabc123abc456abc789abcabc";
     
    
   

    

     

    
    

     

      		String from = "abc";
     
    
   

    

     

    
    

     

      		String to = "def";
     
    
   

    

     

    
    

     

      		String result = replace(target, from ,to);
     
    
   

    

     

    
    

     

      		System.out.print("result:" + result);
     
    
   

    

     

    
    

     
		
     
    
   

    

     

    
    

     

      	}
     
    
   

    

     

    
    

     
	
     
    
   

    

     

    
    

     
	
     
    
   

    

     

    
    

     

      	public static String replace(String target, String from, String to) {
     
    
   

    

     

    
    

     
		
     
    
   

    

     

    
    

     

      		if (target == null || "".equ
