如何消除 java 中的字符串拆分问题？

Question

I have a String like this in my Java Program

String str = ("System.out.print(Numerator?)int");

And i hava a delimiter to split the element

 private static final String DELIMITER = "\"(?:\\\\\"|[^\"])*?\"|[\\s.,;:+*/|!=><@?#%&(){}\\-\\^\\[\\]\\&&]+|int";

and print out

for (String retval: str.split(DELIMITER)){
            System.out.println(retval);
} 

but the output is

System
out
pr

Numerator

i want the output is

System 
out 
print
Numerator

How to fix it by only split the "int" not pr"int".

Answer 1

Alternative:

See context:

public static void main(String[] args) {
    String input = ("System.out.print(Numerator?)int");
    List<String> elements = Pattern.compile("\\W|\\bint\\b").splitAsStream(input).collect(Collectors.toList());
    elements.forEach(System.out::println);
}

Output:

System
out
print
Numerator
