Method

intzeroConvert(String src)
zero Convert 
if (src == null || src.equals("null") || "".equals(src) || " ".equals(src))
    return 0;
else
    return Integer.parseInt(src.trim());
intzerocount(int v)
Return the number of zeros in the binary representation of the value of the argument. 
return bytezeros[v & 0xFF] + bytezeros[(v >> 8) & 0xFF] + bytezeros[(v >> 16) & 0xFF]
        + bytezeros[(v >> 24) & 0xFF];
intzeroCount(long n)
zero Count 
long k;
int count = 63;
if (n == 0) {
    return 64;
k = n << 32;
if (k != 0) {
    count -= 32;
...
doublezeroDiv(double numerator, double denominator)
Returns the division or zero if the denominator is zero. 
return (denominator == 0 ? 0 : numerator / denominator);
intzeroes(final int ch)
Returns the zero base for the specified code point, or -1 . 
for (final int z : ZEROES)
    if (ch >= z && ch <= z + 9)
        return z;
return -1;
StringzeroEsquerda(String s1, int tamString)
zero Esquerda 
while (s1.length() < tamString) {
    s1 = "0" + s1;
return s1;
longzeroExtend(long value, int inputBits)
Zero extend an integer. 
if (inputBits < 64) {
    return value & ~(-1L << inputBits);
} else {
    return value;
voidzeroFill(float[] array)
This method fills the given array of floats with zeros. 
for (int counter = 0; counter < array.length; counter++) {
    array[counter] = 0.0f;
StringzeroFill(int iv, int len)
zero Fill 
String v = String.valueOf(iv);
if (v.length() < len) {
    StringBuilder bd = new StringBuilder(v);
    for (int i = 0; i < len - v.length(); i++) {
        bd.insert(0, '0');
    return bd.toString();
} else {
...
StringzeroFill(int num, int size, String character)
Takes the number num, and displays it with size digits. 
StringBuilder res = new StringBuilder();
String snum = "" + num;
for (int i = snum.length(); i < size; i++) {
    res.append(character);
res.append(snum);
return res.toString().substring(res.length() - size);
