The list of methods to do String Code Point are organized into topic(s).

Method

inttoCodePoint(char high, char low)
to Code Point 
return (high - HIGH_SURROGATE_MIN_VALUE) * 0x400 + (low - LOW_SURROGATE_MIN_VALUE) + 0x10000;
inttoCodePoint(char highSurrogate, char lowSurrogate)
to Code Point 
return MIN_SUPPLEMENTARY_CODE_POINT + ((highSurrogate & 1023) << 10) + (lowSurrogate & 1023);
inttoCodePoint(char[] chars)
to Code Point 
return toCodePoint(chars[0], chars[1]);
int[]toCodePointArray(final String str)
to Code Point Array 
if (str != null) {
    final int len = str.length();
    final int[] acp = new int[str.codePointCount(0, len)];
    for (int i = 0, j = 0; i < len; i = str.offsetByCodePoints(i, 1)) {
        acp[j++] = str.codePointAt(i);
    return acp;
return new int[0];
int[]toCodePointArray(String string)
Transforms a String to its representative array of unicode code points. 
char[] sarray = string.toCharArray();
int[] result = new int[Character.codePointCount(sarray, 0, sarray.length)];
for (int i = 0, j = 0, codePoint = 0; i < sarray.length; i += Character.charCount(codePoint)) {
    codePoint = Character.codePointAt(sarray, i);
    result[j++] = codePoint;
return result;
inttoCodePoints(char[] src, int srcOff, int srcLen, int[] dest, int destOff)
Converts a sequence of Java characters to a sequence of unicode code points. 
if (srcLen < 0) {
    throw new IllegalArgumentException("srcLen must be >= 0");
int codePointCount = 0;
for (int i = 0; i < srcLen;) {
    final int cp = Character.codePointAt(src, srcOff + i, srcOff + srcLen);
    final int charCount = Character.charCount(cp);
    dest[destOff + codePointCount++] = cp;
...
int[]toCodepoints(String message)
to Codepoints 
int[] codepoints = new int[message.length()];
for (int i = 0; i < message.length(); i++) {
    codepoints[i] = message.codePointAt(i);
return codepoints;
int[]toCodePoints(String s)
Convert the string to an array of code points. 
return s.codePoints().toArray();
int[]toCodePoints(String str)
to Code Points 
int count = str.codePointCount(0, str.length());
int[] codePoints = new int[count];
for (int cpIndex = 0, charIndex = 0; cpIndex < count; cpIndex++) {
    int cp = str.codePointAt(charIndex);
    codePoints[cpIndex] = cp;
    charIndex += Character.charCount(cp);
return codePoints;
...
StringtoCodeString(String s)
Given a string, returns a string that could be printed out in Java source code. 
return "\"" + s.replace("\\", "\\\\").replace("\"", "\\\"").replace("\n", "\\n").replace("\t", "\\t")
        + "\"";
