Method

inthashCode(List list)
hash Code 
if (list == null) {
    return 0;
final int prime = 31;
int result = 1;
for (Iterator it = list.iterator(); it.hasNext();) {
    result = prime * result + it.next().hashCode();
return result;
inthashCode(List list)
Computes the hash code for a list per the contract defined by List#hashCode() . 
return listHashCode(list);
inthashCodeForList(final Collection list)
Generates a hash code using the algorithm specified in java.util.List#hashCode() . 
if (list == null) {
    return 0;
int hashCode = 1;
Iterator it = list.iterator();
Object obj = null;
while (it.hasNext()) {
    obj = it.next();
...
inthashContents(List l)
finds a hash value which takes into account the value of all elements, such that two sets for which equivalent(a, b) returns true will hashContents() to the same value 
int out = 0;
int count = 0;
for (Iterator ii = l.iterator(); ii.hasNext(); ++count) {
    Object o = ii.next();
    if (o != null)
        out ^= (o.hashCode() ^ count);
return out;
