Description

The list of methods to do Object Compare are organized into topic(s).

Method

booleanareEqual(Object value, Object otherValue)
A comprehensive isEqual method that handles nulls and arrays safely. 
if (value == otherValue) {
    return true;
if (value == null) {
    return false;
if (otherValue == null) {
    return false;
...
booleanareEqual(Object value1, Object value2)
Compares the two given values by taking null and NaN values into account.
Two null values will be considered equal. 
return ((value1 == null) && (value2 == null)) || (isNaN(value1) && isNaN(value2))
        || ((value1 != null) && value1.equals(value2));
booleanareEqual(T obj1, T obj2)
are Equal 
return (obj1 != null) && obj1.equals(obj2);
voidareEqual(T obj1, V obj2)
are Equal 
areEqual(obj1, obj2, "The object is not equal.");
booleanareEqualComparables(T object1, T object2)
are Equal Comparables 
if (object1 == null) {
    return (object2 == null);
} else if (object2 == null) {
    return false;
return (object1.compareTo(object2) == 0);
booleanareEqualEvenIfBothNull(Object first, Object second)
are Equal Even If Both Null 
return ((first == null && second == null) || (first != null && second != null && first.equals(second)));
booleanareEquals(final Object o1, final Object o2)
Utility method for equals() methods. 
return (o1 == o2) || (o1 != null && o1.equals(o2));
booleanareEquals(Object a, Object b)
are Equals 
if (a == null) {
    return b == null;
return a.equals(b);
booleanareEquals(Object arg0, Object arg1)
Checks if the given objects are equals using the Object#equals(Object) method or the == operator if the first argument is null. 
if (arg0 != null && arg1 != null) {
    return arg0.equals(arg1);
return arg0 == arg1;
booleanareEquals(Object... objs)
are Equals 
boolean areEquals = true;
if (objs != null && objs.length > 1) {
    for (int i = 0; i < objs.length - 1 && areEquals; i++) {
        areEquals &= (objs[i] == null && objs[i + 1] == null)
                || (objs[i] != null && objs[i].equals(objs[i + 1]));
return areEquals;
