在开发过程中，我们往往会遇到将汉字转化为简码的形式，即汉字首字母大写的格式。下面我将介绍一下这个简单的方法：

主要代码：
public class HanziZhuanPinyin {
public static void main(String[] args) {
// TODO Auto-generated method stub
System.out.println(ToFirstChar("医生下达医嘱").toUpperCase()); //转为首字母大写
System.out.println(ToPinyin("医生下达医嘱"));
System.out.println(ToFirstChar("高级工程师").toUpperCase()); //转为首字母大写
}
/**
* 获取字符串拼音的第一个字母
* @param chinese
* @return
*/
public static String ToFirstChar(String chinese){
String pinyinStr = "";
char[] newChar = chinese.toCharArray(); //转为单个字符
HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
for (int i = 0; i < newChar.length; i++) {
if (newChar[i] > 128) {
try {
pinyinStr += PinyinHelper.toHanyuPinyinStringArray(newChar[i], defaultFormat)[0].charAt(0);
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
}
}else{
pinyinStr += newChar[i];
}
}
return pinyinStr;
}
/**
* 汉字转为拼音
* @param chinese
* @return
*/
public static String ToPinyin(String chinese){
String pinyinStr = "";
char[] newChar = chinese.toCharArray();
HanyuPinyinOutputFormat defaultFormat = new HanyuPinyinOutputFormat();
defaultFormat.setCaseType(HanyuPinyinCaseType.LOWERCASE);
defaultFormat.setToneType(HanyuPinyinToneType.WITHOUT_TONE);
for (int i = 0; i < newChar.length; i++) {
if (newChar[i] > 128) {
try {
pinyinStr += PinyinHelper.toHanyuPinyinStringArray(newChar[i], defaultFormat)[0];
} catch (BadHanyuPinyinOutputFormatCombination e) {
e.printStackTrace();
}
}else{
pinyinStr += newChar[i];
}
}
return pinyinStr;
}
}
