Method

StringintArrayAsString(int[] a)
int Array As String 
if (null == a)
    return null;
int len = a.length;
StringBuffer pcs = new StringBuffer(0 < len ? "[" + a[0] : "[");
for (int i = 1; i < len; i++)
    pcs.append(", " + a[i]);
pcs.append(']');
return pcs.toString();
...
StringintArrayToString(final int... ints)
Converts an integer array to a string with only 16-bit charaters 
int len = ints.length;
for (final int i : ints)
    if (i > 0xFFFF)
        len++;
    else if (i > 0x10FFFF)
        throw new RuntimeException("Be serious, there is no character above plane 16.");
final char[] chars = new char[len];
int ptr = 0;
...
StringintArrayToString(int vals[])
Convert an int array to a string 
StringBuilder buf = new StringBuilder();
for (int i = 0; i < vals.length; ++i) {
    buf.append((char) vals[i]);
return buf.toString();
StringintArraytoString(int[] a)
int Arrayto String 
if (a == null)
    return "";
int iMax = a.length - 1;
if (iMax == -1)
    return "";
StringBuilder b = new StringBuilder();
for (int i = 0;; i++) {
    b.append(a[i]);
...
StringintArrayToString(int[] a)
int Array To String 
StringBuilder retval = new StringBuilder();
for (int val : a) {
    retval.append(String.format("%d ", val));
return retval.toString();
StringintArrayToString(int[] a, String separator)
int Array To String 
int len = a.length;
if (len == 0) {
    return "[]";
StringBuilder builder = new StringBuilder();
builder.append("[ ").append(a[0]);
if (len > 1) {
    for (int i = 1; i < a.length; i++) {
...
StringintArrayToString(int[] arr)
Present an int array as a comma separated list string 
String s = "";
if (arr != null)
    for (int i = 0; i < arr.length - 1; i++)
        s += arr[i] + ",";
if (arr.length > 0)
    s += arr[arr.length - 1];
return s;
StringintArrayToString(int[] array)
Creates a string representation of the given array of type int[] (this representation can be parsed using the method parseIntegerArray). 
StringBuilder sb = new StringBuilder();
sb.append("[");
for (int a : array) {
    sb.append(a).append(", ");
if (sb.lastIndexOf(", ") != -1)
    sb.delete(sb.lastIndexOf(", "), sb.length());
sb.append("]");
...
StringintArrayToString(int[] array, boolean whiteSpaceSeperator)
int Array To String 
if (null == array)
    return null;
StringBuffer s = new StringBuffer();
for (int i = 0; i < array.length; i++) {
    s.append(array[i]);
    if (whiteSpaceSeperator)
        s.append(' ');
return s.toString();
StringintArrayToString(int[] ia)
Utility to convert an int[] to a String. 
if (ia == null) {
    return "null";
StringBuilder sb = new StringBuilder("[");
for (int i = 0; i < ia.length; ++i) {
    if (i > 0) {
        sb.append(", ");
    sb.append(ia[i]);
sb.append(']');
return sb.toString();
