如何在Java中按句子将字符串分隔为定界符？
String类的split()方法接受表示定界符的String值，并拆分为标记（单词）数组，将出现两个定界符之间的字符串视为一个标记。
例如，如果将单个空格“”作为此方法的定界符，并尝试拆分String。此方法将两个空格之间的单词视为一个标记，并在当前String中返回一个单词数组（空格之间）。
如果String不包含指定的定界符，则此方法返回一个包含整个字符串作为元素的数组。
示例
public class SplitExample {
public static void main(String[] args) {
String str = "Hi how are you welcome to Nhooo";
String words[] = str.split(" ");
for(String token : words) {
System.out.println(token);
}
}
}输出结果
Hi how are you welcome to Nhooo
用句子分割字符串作为分隔符
如果每次指定的句子出现时，也可以通过传递一个句子作为定界符来分割一个句子，将字符串作为单独的标记进行划分。
示例
随后的Java程序将文件的内容读取到Sting中，并使用split()带有句子作为定界符的方法将其拆分。
public class StringOccurrence {
public static String fileToString(String filePath){
Scanner sc = null;
String input = null;
StringBuffer sb = null;
try {
sc = new Scanner(new File(filePath));
sb = new StringBuffer();
while (sc.hasNextLine()) {
input = sc.nextLine();
sb.append(" "+input);
}
}
catch(Exception ex) {
ex.toString();
}
return sb.toString();
}
public static void main(String args[]) throws FileNotFoundException {
String filePath = "D://sampleData.txt";
String text = fileToString(filePath);
String array[] = text.split("We don’t force our readers to sign up with us or submit their details either");
for(String token : array) {
System.out.println(" ");
System.out.println(token);
}
}
}输出结果
