equals back to summary

equals	back to summary
public boolean equals(final Object obj) Overrides java.lang.Object.equals. Compares this object against the specified object. The result is `true` if and only if the argument is not `null` and is a `Double` object that represents a double that has the identical bit pattern to the bit pattern of the double represented by this object. For this purpose, two `double` values are considered to be the same if and only if the method `Double#doubleToLongBits(double)`returns the same long value when applied to each. Note that in most cases, for two instances of class `Double`,`d1` and `d2`, the value of `d1.equals(d2)` is `true` if and only if: d1.doubleValue() == d2.doubleValue() also has the value `true`. However, there are two exceptions: If `d1` and `d2` both represent `Double.NaN`, then the `equals` method returns `true`, even though `Double.NaN == Double.NaN` has the value `false`. If `d1` represents `+0.0` while `d2` represents `-0.0`, or vice versa, the `equal` test has the value `false`, even though `+0.0 == -0.0` has the value `true`. This allows hashtables to operate properly. Parameters obj:Object the object to compare with, null returns false. Returns:boolean `true` if the objects are the same; `false` otherwise. Annotations @Override

public boolean equals(final Object obj)

Overrides java.lang.Object.equals.

Compares this object against the specified object. The result is true if and only if the argument is not null and is a Double object that represents a double that has the identical bit pattern to the bit pattern of the double represented by this object. For this purpose, two double values are considered to be the same if and only if the method Double#doubleToLongBits(double)returns the same long value when applied to each.

Note that in most cases, for two instances of class Double,d1 and d2, the value of d1.equals(d2) is true if and only if:

d1.doubleValue() == d2.doubleValue()

also has the value true. However, there are two exceptions:

If d1 and d2 both represent Double.NaN, then the equals method returns true, even though Double.NaN == Double.NaN has the value false.
If d1 represents +0.0 while d2 represents -0.0, or vice versa, the equal test has the value false, even though +0.0 == -0.0 has the value true. This allows hashtables to operate properly.

Parameters

obj:Object: the object to compare with, null returns false.

Returns:boolean

true if the objects are the same; false otherwise.
