Method

inthashCode(final Object... array)
hash Code 
if (array == null) {
    return 0;
int result = 1;
Object element;
for (final Object element2 : array) {
    element = element2;
    result = 31 * result + ((element == null) ? 0 : element.hashCode());
...
inthashCode(float value)
hash Code 
return Float.floatToIntBits(value);
inthashCode(int base, int multiplier, boolean fastArrays, Object... relevantValues)
hash Code 
int hashCode = base * multiplier + relevantValues.length;
for (Object value : relevantValues) {
    if (value == null || value.getClass() == Object.class)
        continue;
    if (fastArrays && value instanceof Object[]) {
        Object[] array = (Object[]) value;
        hashCode = hashCode * multiplier + array.length;
        for (int i = 0; i < array.length; i <<= 1) {
...
inthashCode(int currentHashCodeValue, boolean b)
hash Code 
return PRIME * currentHashCodeValue + (b ? 1 : 0);
inthashCode(int mul, Object obj)
hash Code 
if (null != obj) {
    return obj.hashCode() * mul;
return 0;
inthashCode(int num)
Hash the specified int using implementation proposed in Josh Bloch's "Effective Java". 
return 37 * HASH_CODE + num;
inthashCode(int previous, boolean x)
hash Code 
return (PRIME * previous) + (x ? 1 : 0);
inthashCode(int result, Object obj)
hash Code 
result = 37 * result + (obj == null ? 0 : obj.hashCode());
return result;
inthashCode(int val)
hash Code 
return val;
inthashCode(int[] a)
hash Code 
if (a == null)
    return 0;
int result = 1;
for (int element : a)
    result = (31 * result + element) ^ result;
return result;
