Method

StringarrayToRLEString(short[] a)
Construct a string representing a short array. 
StringBuffer buffer = new StringBuffer();
buffer.append((char) (a.length >> 16));
buffer.append((char) a.length);
short runValue = a[0];
int runLength = 1;
for (int i = 1; i < a.length; ++i) {
    short s = a[i];
    if (s == runValue && runLength < 0xFFFF)
...
StringarrayToStr(Object[] arr, char split)
e.g: String[] result={"TYHR0001","TYHR0002"}; split=","; return: str="TYHR0001,TYHR0002"; 
if (arr == null || arr.length == 0) {
    return null;
StringBuffer sb = new StringBuffer();
for (int i = 0; i < arr.length; i++) {
    if (i > 0) {
        sb.append(split);
    sb.append(arr[i]);
return sb.toString();
StringarrayToStr(Object[] arr, char split)
e.g: String[] result={"TYHR0001","TYHR0002"}; split=","; return: str="TYHR0001,TYHR0002"; 
if (arr == null || arr.length == 0) {
    return null;
StringBuffer sb = new StringBuffer();
for (int i = 0; i < arr.length; i++) {
    if (i > 0) {
        sb.append(split);
    sb.append(arr[i]);
return sb.toString();
StringarrayToStr(String[] o)
array To Str 
String str = "";
if (o == null || o.length < 1)
    return "";
for (String s : o)
    str += s + ",";
return str.substring(0, str.length() - 1);
StringArrayToStr(String[] strArr, String seperatedBy)
Array To Str 
String str = "";
for (int i = 0; i < strArr.length; i++) {
    str += strArr[i] + seperatedBy;
return str;
StringarrayToStr(String[] strArray)
array To Str 
StringBuffer strBuffer = new StringBuffer();
for (String str : strArray) {
    strBuffer.append(strBuffer.length() > 0 ? "," : "").append(str);
return strBuffer.toString();
StringarrayToString(byte[] arg)
array To String 
StringBuffer s = new StringBuffer(arg.toString());
s.append(" : ");
for (int i = 0; i < arg.length; ++i) {
    s.append(arg[i]);
    s.append(" ");
return s.toString();
StringarrayToString(byte[] array)
Pretty-prints a byte array 
StringBuilder result = new StringBuilder("[");
for (int index = 0; index < array.length - 1; ++index) {
    result.append(array[index]).append(",");
if (array.length > 0) {
    result.append(array[array.length - 1]);
result.append("]");
...
StringarrayToString(byte[] bytes)
array To String 
StringBuilder result = new StringBuilder(bytes.length * 4);
int i = 0;
while (i < bytes.length) {
    int value = bytes[i] & 0xFF;
    result.append(hexChar(value / 16));
    result.append(hexChar(value % 16));
    i++;
    if (i % BYTES_PER_LINE == 0) {
...
StringarrayToString(byte[] source, int index, short size)
array To String 
byte[] array = new byte[size * 2];
for (int i = index; i <= (size * 2) + 2; i++) {
    array[i - index] = source[i];
String string = "UNDEFINED";
try {
    string = new String(array, 0, array.length, "UTF-16BE");
} catch (UnsupportedEncodingException e) {
