从字符串java拆分文本

Question

I am having a long text which i want to split in to small sentences.The following is my text.

I tried Count words in a string method? but there the solution given was to split the string return trim.split("\\\\s+").length; . In my text i don't have any spaces.

సోషలిజం,అనే,మాటను,గబ్బు,పట్టించడమే,కాంగ్రెసు,వారి,వ్యూహమనీ,అంతవరకూ,ప్రజలలో,సోషలిజం,యెడవున్న,అభిమానాన్ని,ఎక్స్‌ప్లాయిట్,చెయ్యడం,దాని,ఎత్తుగడ,అనీ,అంటే,ఓ,మాటు,నా,మీద,పడిపోయావు,గుర్తుందా.

I know split() is used to split the string. But i don't know how to split above text as there is no space or any other regular expression to split with.

The following code works for splitting the text

String string = "1234,56,789,10,1111111,1111112,12";
char[] ch = string.toCharArray();  
int comma_limit = 3;
int comma_count = 0;
for(int i=0;i<ch.length;i++) 
if (ch[i] == ',') {
    comma_count = comma_count + 1;

if (comma_count % comma_limit == 0)
{
ch[i] = '.';
System.out.println(ch);

     }
  }

Answer 1

使用带有逗号分隔符的split方法，它将返回分隔字符串的数组，然后使用length方法，获取其大小

System.out.println(yourString.split(",").length);

Answer 2

static IEnumerable<string> Split(string str, int chunkSize)
{
    return Enumerable.Range(0, str.Length / chunkSize)
        .Select(i => str.Substring(i * chunkSize, chunkSize));
}

You need to check for corner cases.

Answer 3

In the split use the "," to split based on the comma character. return trim.split(",").length;

Answer 4

If you want to split it into specific parts use this.

String text = "SAMPLEs"; // <- this will contain the large text
int numberOfParts = 2; // the number of split parts

int partLength = text.length() / numberOfParts;

ArrayList<String> parts = new ArrayList<>();

for (int i = 0; i < numberOfParts; i++) {
    int start = partLength * i;
    int end = start + partLength;
    parts.add(text.substring(start, end));
    if (text.length() - end < partLength) {
        parts.add(text.substring(end, text.length()));
    }
}

for (int i = 0; i < parts.size(); i++) {
    System.out.println("PART " + i + " contains : " + parts.get(i));
}

Result:

PART 0 contains : SAM
PART 1 contains : PLE
PART 2 contains : s

Answer 5

You can split using the comma character

String text = "సోషలిజం,అనే,మాటను,గబ్బు,పట్టించడమే,కాంగ్రెసు,వారి,వ్యూహమనీ,అంతవరకూ,ప్రజలలో,సోషలిజం,యెడవున్న,అభిమానాన్ని,ఎక్స్\u200Cప్లాయిట్,చెయ్యడం,దాని,ఎత్తుగడ,అనీ,అంటే,ఓ,మాటు,నా,మీద,పడిపోయావు,గుర్తుందా.";
String[] lines = text.split(",");
for (int i = 0; i < lines.length; i++) {
    System.out.println("SENTANCE  " + i + "  : "+ lines[i]);
}

Answer 6

Use String Builder instead of string

StringBuilder sb = new StringBuilder();
sb.append("సోషలిజం,అనే,మాటను,గబ్బు,పట్టించడమే,కాంగ్రెసు,వారి,వ్యూహమనీ,అంతవరకూ,ప్రజలలో,సోషలిజం,యెడవున్న,అభిమానాన్ని,ఎక్స్‌ప్లాయిట్,చెయ్యడం,దాని,ఎత్తుగడ,అనీ,అంటే,ఓ,మాటు,నా,మీద,పడిపోయావు,గుర్తుందా");

int totalString = sb.toString().splitby(",").lenght();

Answer 7

Here is substring example you have asked.

String longText = "సోషలిజం,అనే,మాటను,గబ్బు,పట్టించడమే,కాంగ్రెసు,వారి,వ్యూహమనీ,అంతవరకూ,ప్రజలలో,సోషలిజం,యెడవున్న,అభిమానాన్ని,ఎక్స్\u200Cప్లాయిట్,చెయ్యడం,దాని,ఎత్తుగడ,అనీ,అంటే,ఓ,మాటు,నా,మీద,పడిపోయావు,గుర్తుందా.";
int longTextLength = longText.length();
int partLength  = (int) longTextLength / 3;
String part1 = longText.substring(0, partLength);
String part2 = longText.substring(partLength, 2*(partLength));
String part3 = longText.substring(2*(partLength), longTextLength);

Answer 8

I am confused by what you are asking. Assuming that you are looking to implement some sort of word wrapping, you can do as follows. It may not be the Best way to do it, but it is a way to do it.

divideString("This is my sentence! I would like to split this into 3 Strings with about the same length.", 3);

public static void divideString(String raw, int numberOfDivides) {
    int charsPerString = raw.length()/numberOfDivides;
    String[] refined = new String[charsPerString];
    for(int i=1; i < (raw.length()/charsPerString)+1; i++) {
        refined[i] = raw.substring((charsPerString*i)-charsPerString, charsPerString*i);
        System.out.println(refined[i]);
    }
}

Which would output the following:

This is my sentence! I would l
ike to split this into 3 Strin
gs with about the same length.

Check this once you will get 3 Strings inside loop, You can increase split count..

    public void splitStr(){
        String str = "";
        String[] split_str = str.split(",");

        int len = split_str.length;

        int split_len = len/3;

        for (int i = 0; i< len; i++){
            String f1 ="";
            if(i == split_len){
                // first string 
                f1 = split_str[i];

                // You will get 3   f1 strings
                split_len += split_len+ i;
            }
        }
    }
