Question

我想打破.上的字符串（句号）。

实施例。 String str="We are going there.How are you."

然后输出

We are going there.
How are you.

它应该拆分为“。” 但如果我的字符串是

Dr.Harry is going.那么它不应该像

那样破坏

Dr.
Harry is going.

它应该是Dr.Harry is going.。

就像我有一些话，如果他们有字符串，那么它不应该破坏

StringBuffer regex = new StringBuffer("Dr[\\.]|Gr[\\.]|[Aa][\\.][Mm][\\.]|"+ "[Pp][\\.][Mm][\\.]|Emp[\\.]|Rs[\\.]|Ms[\\.]|No[\\.]|Nos[\\.]|"+ "Dt[\\.]|Sh[\\.]|(Mr|mr)[\\.]|(Mrs|mrs)[\\.]|Admn[\\.]|Ad[\\.]|Smt[\\.]|"+ "GOVT[\\.]|Govt[\\.]|Deptt[\\.]|Tel[\\.]|Secy[\\.]|Estt[\\.]|"+ "Asstt[\\.]|Hqrs[\\.]|DY[\\.]|Supdt[\\.]|w[\\.]e[\\.]f[\\.]|"+ "I[\\.]|N[\\.]|[0-9]+[\\.][0-9]+[\\.][0-9]|K[\\.]|NSI[\\.]|"+ "Prof[\\.]|Dte[\\.]|no[\\.]|nos[\\.]|Agri[\\.]|R[\\.]|"+ "K[\\.]|Y[\\.]|C[\\.]|N[\\.]|Dept[\\.]|S[\\.]|Spl[\\.]|N[\\.]|"+ "Sr[\\.]|Addl[\\.]|i[\\.]e[\\.]|Sl[\\.]|CS[\\.]|M[\\.]|IPS[\\.]|"+ "Jt[\\.]|viz[\\.]|hrs[\\.]|S/Sh[\\.]|Jr[\\.]|E[\\.]|S[\\.]|"+ "Pers[\\.]|Deptts[\\.]|OM[\\.]|DT[\\.]|Proj[\\.]|Instrum[\\.]|"+ "Div[\\.]|Dev[\\.]|Env[\\.]|e[\\.]g[\\.]|etc[\\.]|Misc[\\.]|"+ "vig[\\.]|Dr[\\.]|Nos[\\.]|Ltd[\\.]|Maj[\\.]|"+ "Gen[\\.]|MAJ[\\.]|GEN[\\.]|Su[\\.]|/Ess[\\.]|Com[\\.]|St[\\.]|");

这些是一些字符串，如果它们来的话不应该分割。就像Dr.Harry一样。有可能是正则表达吗？或任何其他方法？谢谢

Answer 1

使用它：

搜索：(?<!(Mr|Dr|Gr|Aa))\.

替换：\n

您可以在|之后使用Aa添加任意数量的字词。

我尝试了下面的代码，它对我来说很好用：

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Ideone
{
    public static void main (String[] args) throws java.lang.Exception
    {
    String str1 = "We are going there.How are you.Mr.Gordon is also coming with us.Are you sure you want to take him", str2;
    String substr = "\n", regex = "(?<!(Mr|Dr|Gr|Aa))\\.";

    // prints string1
    System.out.println("String = " + str1);

    /* replaces each substring of this string that matches the given
    regular expression with the given replacement */
    str2 = str1.replaceAll(regex, substr);    
    System.out.println("After Replacing = " + str2);
    }
}

输出：

We are going there
How are you
Mr.Gordon is also coming with us
Are you sure you want to take him

Answer 2

使用此正则表达式：

(?<!(Dr|Gr|Aa|Mm|Pp))\.

根据需要填写其余部分。这使用Lookaround

完全停止字符串
