如何在使用特殊符号拆分字符串并将特殊符号包含到第一个子字符串后从字符串中获取子字符串？

I want to split the string with semicolon into array of strings, but whenever it is splitting the string with semicolon I need to add that semicolon to the first splitting string. It is adding to the next splitting screen.

我想用分号将字符串拆分为字符串数组,但每当用分号拆分字符串时,我需要将分号添加到第一个拆分字符串。它正在添加到下一个分割屏幕。

String sampleContent="hello ; hai ;  come fast ;";
            String SQLScripts[] = sampleContent.split("(?=\\;)",-1);
            System.out.println(" SQLSCript Length is:"+SQLScripts.length);
            for(int m=0;m<SQLScripts.length;m++){
                System.out.println("After SQLScripts spliting with semi colon is : "+SQLScripts[m]);
            }`

The output that I am expecting is:

我期待的输出是:

 SQLSCript Length is:4
After SQLScripts spliting with semi colon is : hello ;
After SQLScripts spliting with semi colon is : hai ;
After SQLScripts spliting with semi colon is : come fast ;

The output that I am getting is:

我得到的输出是:

 SQLSCript Length is:4
After SQLScripts spliting with semi colon is : hello 
After SQLScripts spliting with semi colon is : ; hai 
After SQLScripts spliting with semi colon is : ;  come fast 
After SQLScripts spliting with semi colon is : ;

Try to use this regex "(?<=;)",-1 you can incluse ;:

尝试使用这个正则表达式“(?<=;)”, - 1你可以包括;:

  public static void main(String[] args) {
    String sampleContent = "hello ; hai ; come fast ;";
    String SQLScripts[] = sampleContent.split("(?<=;)",-1);
    System.out.println("SQLSCript Length is:"+SQLScripts.length);
    for(int m=0;m<SQLScripts.length-1;m++){
        System.out.println("After SQLScripts spliting with semi colon is : "+SQLScripts[m]);
    }
  }

Output:

  SQLSCript Length is:4
  After SQLScripts spliting with semi colon is : hello ;
  After SQLScripts spliting with semi colon is :  hai ;
  After SQLScripts spliting with semi colon is :  come fast ;

You can use this regex based on lookbehind:

您可以根据lookbehind使用此正则表达式:

String sampleContent="hello ; hai ;  come fast ;";
String SQLScripts[] = sampleContent.split("(?<=;)\\s+");
System.out.println(" SQLSCript Length is:"+SQLScripts.length);
for(int i=0;i<SQLScripts.length;i++){
    System.out.println("After SQLScripts spliting with semi colon is : "+SQLScripts[i]);
}

Output:

 SQLSCript Length is:3
After SQLScripts spliting with semi colon is : hello ;
After SQLScripts spliting with semi colon is : hai ;
After SQLScripts spliting with semi colon is : come fast ;
