Method

StringarrayToString(int[] array)
Show tasks with standard format 
if (array.length == 0) {
    return ""; 
String msg = ""; 
int preTask = array[0];
msg += preTask;
boolean isContinue = false;
for (int i = 1; i < array.length; i++) {
...
StringarrayToString(int[] array)
array To String 
StringBuilder sb = new StringBuilder();
for (int i = array.length - 1; i >= 0; i--) {
    sb.append(array[i]);
return sb.toString();
StringarrayToString(int[] ary)
array To String 
if (ary == null || ary.length == 0)
    return "";
int m = ary.length - 1;
StringBuilder sb = new StringBuilder();
for (int i = 0;; i++) {
    sb.append(ary[i]);
    if (i == m)
        return sb.toString();
...
StringarrayToString(int[] c, String separator)
array To String 
StringBuffer sb = new StringBuffer();
for (int i = 0; i < c.length; i++) {
    if (i > 0) {
        sb.append(separator);
    sb.append(c[i]);
return sb.toString();
...
StringarrayToString(int[] s)
Translate an array of int-s specifying throw height into a String that uses the normal siteswap notation. 
StringBuilder sb = new StringBuilder();
for (int i = 0; i < s.length; i++) {
    try {
        sb.append(intToChar(s[i]));
    } catch (Exception e) {
        return null;
return sb.toString();
StringarrayToString(int[] subset)
array To String 
StringBuilder sb = new StringBuilder("[");
for (int i = 0; i < subset.length - 1; ++i)
    sb.append(subset[i] + ",");
sb.append(subset[subset.length - 1] + "]");
return sb.toString();
StringarrayToString(int[][] array)
array To String 
ByteArrayOutputStream out = new ByteArrayOutputStream();
for (int i = 0; i < array.length; i++) {
    for (int j = 0; j < array[0].length; j++) {
        out.write(array[i][j]);
return new String(out.toByteArray());
StringarrayToString(Object arbitraryArray)
Converts an array (either Object[] or of a primitive type) to a String containing it's elements in square brackets. 
Class<?> compType = arbitraryArray.getClass().getComponentType();
if (compType == null)
    throw new IllegalArgumentException();
if (compType.isPrimitive()) {
    if (compType == Integer.TYPE)
        return Arrays.toString((int[]) arbitraryArray);
    else if (compType == Long.TYPE)
        return Arrays.toString((long[]) arbitraryArray);
...
StringarrayToString(Object array)
Convenience method. 
if (array == null)
    return "null";
else
    return arrayToString((Object[]) array);
StringarrayToString(Object array)
Returns a string representation of the given array. 
if (array == null) {
    throw new NullPointerException();
if (array instanceof int[]) {
    return Arrays.toString((int[]) array);
if (array instanceof long[]) {
    return Arrays.toString((long[]) array);
