java 将一个字符串里连续两个及以上数字反转

所要的效果:

oldStr>>>123asd1256fsad12345fe1e12et56789sdf1af123
newStr>>>321asd6521fsad54321fe1e21et98765sdf1af321

 1 public static void main(String[] args) {

 2   String str = "123asd1256fsad12345fe1e12et56789sdf1af123";

 3   System.out.println("oldStr>>>"+str);

 4   StringBuffer newStr = new StringBuffer();

 5   String[] strArray = str.split("\\d{2,}+");

 6   String[] newStrArray = new String[strArray.length];

 7 

 8   for(int i=0;i<strArray.length;i++){

 9     newStr.append(strArray[i]);

10     if(i+1<strArray.length){

11       newStrArray[i] = str.substring(str.indexOf(strArray[i]), str.indexOf(strArray[i+1]));

12     }else{

13       newStrArray[i] = str.substring(str.indexOf(strArray[i]), str.length());

14     }

15     newStrArray[i] =new StringBuffer(newStrArray[i].replace(strArray[i], "")).reverse().toString();

16     newStr.append(newStrArray[i]==null?"":newStrArray[i]);

17 

18   }

19   System.out.println("newStr>>>"+newStr);

20 

21 }
