Java implements the method of converting Chinese characters into hanyu pinyin

This article illustrates the method of Java to convert Chinese characters into pinyin. Share with you for your reference, as follows:

Wandering around on the Internet, I came across a very interesting tool named pinyin4j, which can convert Chinese characters into hanyu pinyin. By combining his words with lucene and Chinese word segmentation, I can make a full-text search function similar to Google by typing hanyu pinyin. The code for the implementation is as follows

package pinyin4j;
import net.sourceforge.pinyin4j.PinyinHelper;
import net.sourceforge.pinyin4j.format.HanyuPinyinCaseType;
import net.sourceforge.pinyin4j.format.HanyuPinyinOutputFormat;
import net.sourceforge.pinyin4j.format.HanyuPinyinToneType;
import net.sourceforge.pinyin4j.format.HanyuPinyinVCharType;
import net.sourceforge.pinyin4j.format.exception.BadHanyuPinyinOutputFormatCombination;
public class pinyin4jTest {
  public static void main(String argsp[]) {
    try {
      String output = pinyin4jTest.CNToPinyin(" How are you and how are you ", null);
      System.out.println(output);
    } catch (BadHanyuPinyinOutputFormatCombination e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
    }
  }
  
  public static String CNToPinyin(String inputCN, String seg)
      throws BadHanyuPinyinOutputFormatCombination {
    char[] inputArray = inputCN.toCharArray();
    if (seg == null)
      seg = " ";
    HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
    format.setCaseType(HanyuPinyinCaseType.LOWERCASE);
    format.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
    format.setVCharType(HanyuPinyinVCharType.WITH_V);
    String output = "";
    String[] temp = new String[10];
    for (int i = 0; i < inputArray.length; i++) {
      temp = PinyinHelper.toHanyuPinyinStringArray(inputArray[i], format);
      //If the input Chinese character is polyphonic, different pronunciations will be put into temp[], if not polyphonic, only temp[0] has a value
      for (int j = 0; j < temp.length; j++) {
        output += temp[j] + seg;
      }
    }
    return output;
  }
}

I hope this article has been helpful to you in Java programming.
