Description

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

Method

booleanareEqual(final Object x, final Object y)
Like the legacy #equals method, but handles array-specific checks 
if (x == y) {
    return true;
if (x == null || y == null) {
    return false;
if (x.equals(y)) {
    return true;
...
booleanareEqual(Object o1, Object o2)
This is a utility method that compares two objects when one or both of the objects might be null The result of this method is determined as follows:
  1. If o1 and o2 are the same object according to the == operator, return true. 
    if (o1 == o2) {
    return true;
} else if (o1 == null || o2 == null) {
    return false;
} else {
    return o1.equals(o2);
booleanareEqual(Object o1, Object o2)
Determines is two objects are equal, accounting for one or both objects being null or the two objects being array types. 
boolean objectsAreEqual = false;
if (o1 == o2) {
    objectsAreEqual = true;
} else if (o1 != null && o2 != null) {
    if (o1.getClass().isArray() && o2.getClass().isArray()) {
        objectsAreEqual = Arrays.equals((Object[]) o1, (Object[]) o2);
    } else {
        objectsAreEqual = o1.equals(o2);
...
booleanareEqualStr(Object o1, Object o2)
are Equal Str 
if (o1 == o2) {
    return true;
return nvlStr(o1, "").equals(nvlStr(o2, ""));
booleandeepEquals(Object o1, Object o2)
Determines if two objects are equal as determined by Object#equals(Object) , or "deeply equal" if both are arrays. 
if (o1 == o2) {
    return true;
if (o1 == null || o2 == null) {
    return false;
Class<?> type1 = o1.getClass();
Class<?> type2 = o2.getClass();
...
booleanequalObjects(Object object1, Object object2)
Indicates whether the given objects are "equal to" each other. 
if (object1 == object2) {
    return true;
if (object1 == null) {
    return false;
if (object1.getClass().isArray()) {
    if ((object1 instanceof byte[]) && (object2 instanceof byte[])) {
...
booleanequals(BSONObject a, BSONObject b)
BSON objects are considered equal when their binary encoding matches 
return a.keySet().equals(b.keySet()) && Arrays.equals(BSON.encode(a), BSON.encode(b));
booleanequals(final Object a, final Object b)
Check whether two objects are equal 
Class<?> c;
if (a == b) {
    return true;
if ((a == null) || (b == null)) {
    return false;
c = a.getClass();
...
booleanequals(Object a, Object b)
equals 
if (a instanceof double[] && b instanceof double[]) {
    return Arrays.equals((double[]) a, (double[]) b);
if (a instanceof float[] && b instanceof float[]) {
    return Arrays.equals((float[]) a, (float[]) b);
if (a instanceof long[] && b instanceof long[]) {
    return Arrays.equals((long[]) a, (long[]) b);
...
booleanEquals(Object in1, Object in2)
Equals 
if (in1 instanceof int[])
    return Arrays.equals((int[]) in1, (int[]) in2);
else {
    if (((Object[]) in1).length != ((Object[]) in2).length)
        return false;
    for (int i = 0, s = ((Object[]) in1).length; i < s; i++)
        if (!Equals(((Object[]) in1)[i], ((Object[]) in2)[i]))
            return false;
