Method

booleanareEqual(Object o1, Object o2)
Does a generic object comparison where one or both of the objects could be null. 
if (o1 == o2)
    return true;
else if (o1 == null || o2 == null)
    return false;
else
    return o1.equals(o2);
booleanareEqual(Object o1, Object o2)
Checks whether two objects are equal. 
Object obj1 = nvl(o1, "");
Object obj2 = nvl(o2, "");
return obj1.equals(obj2);
booleanareEqual(Object o1, Object o2)
are Equal 
return (o1 == o2) || (o1 != null && o2 != null && o1.equals(o2));
booleanareEqual(Object obj, Object obj2)
are Equal 
if (obj == null) {
    return obj2 == null;
} else {
    return obj.equals(obj2);
booleanareEqual(Object obj1, Object obj2)
Tests whether two object references refer to equal objects. 
if (obj1 == obj2) {
    return true;
} else if (obj1 == null || obj2 == null) {
    return false;
} else {
    return obj1.equals(obj2);
booleanareEqual(Object obj1, Object obj2)
are Equal 
if ((obj1 == null) || (obj2 == null)) {
    if (obj1 != obj2) {
        return false;
} else if (!obj1.equals(obj2)) {
    return false;
return true;
...
booleanareEqual(Object obj1, Object obj2)
Returns true if the two specified objects are the same. 
return (obj1 == obj2) || (obj1 == null ? false : obj1.equals(obj2));
booleanareEqual(Object object1, Object object2)
Returns true if the two objects are either both null, or equal. 
if (object1 != null && object2 != null)
    return (object1.equals(object2));
else if (object1 == null && object2 != null)
    return false;
else if (object1 != null && object2 == null)
    return false;
return true;
booleanareEqual(Object one, Object another)
Return true if one is equal to another. 
boolean result = (one == null ? another == null : one.equals(another));
return result;
booleanareEqual(Object parameter, Object otherParameter)
are Equal 
if (parameter == null && otherParameter == null)
    return true;
if (parameter != null && otherParameter == null)
    return false;
if (parameter == null && otherParameter != null)
    return false;
return parameter.equals(otherParameter);
