下面是我的文本
Welcome to java programming 1) Oops concepts a) Encapsulation A) Abstraction I) Inheritance • Polymorphism
2)sample program on java 1.Project source code
sample text files • sample.txt b)sam.txt
我想根据下面的模式分割文本，并删除项目符号
1)any bullet 1)I)a)A)•
2)followed by space
3)followed by uppercase word
所以我想生成以下结果
Welcome to java programming
Oops concepts
Encapsulation
Abstraction
Inheritance
Polymorphism
sample program on java
Project source code
Please suggest me how to do this

sample.txt
sam.txt感谢
以下基于正向前瞻的正则表达式应该适用于您：
String s = "Welcome to java programming 1) Oops concepts a) Encapsulation A) Abstraction I) Inheritance • Polymorphism";
String[] arr = s.split("\s*([a-zA-Z\d][).]|•)\s*(?=[A-Z])");
System.out.println("Split => " + Arrays.toString(tok));
输出：
Split => [Welcome to java programming, Oops concepts, Encapsulation, Abstraction, Inheritance, Polymorphism]
这将起作用：
public static void main(String[] args) throws Exception {
final String s = "Welcome to java programming 1) Oops concepts a) Encapsulation A) Abstraction I) Inheritance • Polymorphism";
final String[] split = s.split("\s*(\w\)|•)\s*");
for (final String bullet : split) {
System.out.println(bullet);
}
}
正则表达式是
\s*(\w\)|•)\s*
\s*-零个或多个空格(\w\)|•)-后面跟着括号或项目符号的数字或字母\s*-零个或多个空格
输出：
Welcome to java programming
Oops concepts
Encapsulation
Abstraction
Inheritance
Polymorphism
你也可以试试
String str="Welcome to java programming 1) Oops concepts a) Encapsulation A) Abstraction I) Inheritance • Polymorphism" ;
String newStr=str.replaceAll("(?i)\s*([\d\w]\)|•)\s*"," ISseperatorIS ");
String[] arr=newStr.split("ISseperatorIS ");
for(String i:arr){
System.out.println(i);
}
输出
Welcome to java programming
Oops concepts
Encapsulation
Abstraction
Inheritance
Polymorphism
public class Bullet {
public static void main(String [] args){
String str = "Welcome to java programming 1) Oops concepts a) Encapsulation A) Abstraction I) Inheritance • Polymorphism2)sample program on java 1.Project source code sample text files • sample.txt b)sam.txt";
String [] bullet = str.split("[0-9]\)|[A-Z]\)|[a-z]\)|•|[0-9]\.");
for(String i:bullet){
System.out.println(i);
}
}
}
输出<\p>
