Enhance the string capability of j2m‑split string (with source code)

After jdk1.4, the split method is added to the string class to implement string segmentation, but this method is not available in the j2_m2.0. However, in actual use, in some cases, we do need to use this operation. Here we share some of the code I previously implemented with you. If you have any shortcomings, I would like to give you more comments and suggestions:

 

/**

* String splitting principle: checks the string to be split and then obtains the substring.

* @ Param Original: string to be split

* @ Paran RegEx split string

* @ Return: The String Array generated after the split

*/

Private Static string [] Split (string original, string RegEx)

{

// Obtain the starting position of the substring

Int startindex = 0;

// Put the result data into the vector first

Vector v = new vector ();

// Returned result string array

String [] STR = NULL;

// Store the starting position of the substring

Int Index = 0;

// Obtain the position of the matched substring

Startindex = original. indexof (RegEx );

// System. Out. println ("0" + startindex );

// If the position of the starting string is smaller than the length of the string, it indicates that it is not obtained to the end of the string.

//-1 indicates that the end is obtained.

While (startindex <original. Length () & startindex! =-1)

{

String temp = original. substring (index, startindex );

System. Out. println ("" + startindex );

// Obtain the substring

V. addelement (temp );

// Set the starting position of the substring

Index = startindex + RegEx. Length ();

// Obtain the position of the matched substring

Startindex = original. indexof (RegEx, startindex + RegEx. Length ());

}

// Obtain the end substring

V. addelement (original. substring (index + 1-RegEx. Length ()));

// Convert a vector object to an array

STR = new string [v. Size ()];

For (INT I = 0; I <v. Size (); I ++)

{

STR [I] = (string) v. elementat (I );

}

// Return the generated Array

Return STR;

}
