Description

The list of methods to do Hash Code Calculate are organized into topic(s).

Method

inthashCode(Object array)
hash Code 
if (array == null) {
    return 0;
} else if (!array.getClass().isArray()) {
    return array.hashCode();
} else {
    int hashCode = 17;
    int i;
    if (array instanceof long[]) {
...
inthashCode(Object o)
Note that this method doesn't work for arrays currently. 
return (o == null) ? 0 : o.hashCode();
inthashCode(Object o)
Returns the hash code of the object, handling |null|. 
if (o == null) {
    return 0;
return o.hashCode();
inthashCode(Object o)
hash Code 
if (o == null) {
    return 0;
return o.hashCode();
inthashCode(Object o1, Object o2)
hash Code 
int hash = 7;
if (o1 != null)
    hash = 29 * hash + o1.hashCode();
if (o2 != null)
    hash = 29 * hash + o2.hashCode();
return hash;
inthashCode(Object obj)
Returns a hash code for a possibly null object. 
return obj == null ? 0 : obj.hashCode();
inthashcode(Object obj)
hashcode 
return obj == null ? 0 : obj.hashCode();
inthashCode(Object obj)
Returns the hashcode of obj considering that obj may be null. 
int result;
if (null == obj) {
    result = 0;
} else {
    result = obj.hashCode();
return result;
inthashCode(Object obj)

Gets the hash code of an object returning zero when the object is null.

 ObjectUtils.hashCode(null)   = 0 ObjectUtils.hashCode(obj)    = obj.hashCode() 
return (obj == null) ? 0 : obj.hashCode();
inthashCode(Object obj)
Return a zero hashCode if the object is null, otherwise return the real hashCode 
if (obj == null) {
    return 0;
return obj.hashCode();
